Description
Technical Field
The invention relates to the field of organic photoelectricity, in particular to an intrinsic quinoid near infrared receptor small molecule, a preparation method and application thereof.
Background
Organic Photodetectors (OPDs) are organic photoelectric devices having a photoelectric conversion function, which can convert incident light into an electrical signal for output. Compared with the traditional inorganic semiconductor photoelectric detector, the OPDs have the advantages of low cost, low power consumption, capability of realizing solution processing, flexible device preparation and the like. Meanwhile, the active layer material with various molecular structures is benefited, and the detection range can be covered from an ultraviolet light wave band to an infrared light wave band. Light with the wavelength range of 780-2500nm is called near infrared light, and the near infrared light is taken as an important component of electromagnetic spectrum, and can be widely applied to navigation, aerospace, weapon detection, night vision and other aspects in military; the method can be widely applied to communication, atmosphere monitoring, pollution detection, weather and other aspects in civil use. However, the current widely-used silicon photodetectors have a detection range of only 1100nm, so in order to achieve effective detection of near infrared light exceeding 1100nm and become a potential substitute for silicon photodetectors, the absorption spectrum of the active layer material in OPDs needs to exceed 1100nm.
The active layer of bulk heterojunction OPDs is typically composed of a blend of electron-rich p-type material and electron-deficient n-type material. Since n-type fullerene receptors and derivatives thereof have excellent electron transport properties in three dimensions, researchers have been widely used as n-type materials in combination with various near infrared p-type materials in near infrared organic photodetectors. However, fullerenes and derivatives thereof have the disadvantage that the structure is difficult to adjust and the energy level is difficult to adjust, and it is difficult to achieve good energy level matching with a wide variety of near infrared donor materials, thereby resulting in poor exciton dissociation and charge collection efficiency. Finally, OPDs devices based on near infrared p-type donor materials and n-type fullerene receptors tend to have poor External Quantum Efficiency (EQE), responsivity (R) and detection rate (D x) (adv.funct. Mater.2014,24,7605-7612;Adv.Mater.2020,2003818;Adv.Optical Mater.2018,1800038;J.Mater.Chem.C 2018,6,11645-11650). For example, zhiyuanWang et al in 2018 reported a near infrared P-type donor material P2 with an ultra-narrow optical bandgap (adv. Optical mate. 2018, 1800038). With P2 and fullerene acceptor PC 71 The detection range of the organic photodetector with BM as an active layer material exceeds 1400nm, but after the device is applied with-2V bias to promote exciton dissociation, the EQE response value at the wavelength of 1100nm is only 5%, and the corresponding responsivity is only 0.04A/W.
Therefore, it is needed to find a technical solution to solve the technical problems in the art.
Disclosure of Invention
In recent years, n-type non-fullerene receptor small molecules represented by ITIC and Y6 are rapidly developed, and near infrared absorption and continuously adjustable energy levels can be realized through reasonable molecular structure design. For organic semiconductors, the introduction of intrinsic quinoid units by structural design is an effective strategy to achieve near infrared absorption. Under the driving action of the aromatic stabilization energy, the intrinsic quinoid structure can obviously improve the quinoid content in the conjugated framework, thereby reducing the optical band gap. Meanwhile, all the constituent units of the modularized non-fullerene receptor small molecule are connected through single bonds, so that the method has the advantages of low synthesis complexity and low cost, but no modularized non-fullerene receptor small molecule with the absorption spectrum exceeding 1200nm is reported at present.
Therefore, the invention utilizes the advantages of reduced band gap and low complexity of the modularized structure by the intrinsic quinoid structure, takes the intrinsic quinoid Q unit as the core unit, firstly invents the intrinsic quinoid near-infrared receptor small molecule, one of which is near-infrared modularized non-fullerene receptor small molecule BDP4Cl with an A-D-Q-D-A structure, the absorption spectrum of which exceeds 1400nm, the EQE value of the photoelectric detector based on the photoelectric detector at 1100nm is up to 16.40% under the condition of not applying any bias, and the corresponding responsivity and detection rate are 0.15A/W and 7.7X10 respectively 11 Jones. And the BDP4 Cl-based detector has a large cut-off bandwidth (65 kHz) and a wide linear dynamic range (70 dB) for 1050nm incident light, so that the high-performance near-infrared organic photoelectric detector is realized.
Furthermore, the invention designs and synthesizes a series of A-D-Q-D-A near infrared small molecule acceptor materials with the intrinsic quinoid unit as a central core, and the near infrared organic photoelectric detector prepared based on the materials also realizes high-performance detection of near infrared light exceeding 1100nm, which proves that the technical scheme of the invention has wide universality and feasibility.
In the comparative examples of the examples section in the description of the present invention, it can be seen that the detection range of the non-fullerene acceptor small molecule DC4Cl of the A-D-D-A structure containing no intrinsic quinoid Q unit is within 1100nm in comparison. Further, non-fullerene acceptor small molecules DPPO4Cl and IIDCN with similar structures A-D-A-D-A, but with core structures incapable of forming intrinsic quinone Q units, can achieve EQE response spectra exceeding 1100nm, but with 0V bias, the EQE response at 1100nm is only about 1%. And, despite the introduction of the strongly electron withdrawing unit BTT as a nuclear structure, it is also possible to realize an EQE response spectrum exceeding 1100nm, and the EQE response at 1100nm is only 2% at 0V bias.
In the above comparative examples, the core structure was not able to effectively form an intrinsic quinoid structure. This illustrates that the introduction of an intrinsic quinoid Q unit is an effective method for inventing high performance near infrared modular non-fullerene receptor small molecules.

Test case
Test example 1
All near infrared receptor small molecules obtained in the above examples and comparative examples are taken as examples, and the application of the near infrared receptor small molecules in a near infrared organic photodetector is illustrated.
The specific preparation process of each near infrared organic photoelectric detector is as follows:
and spin-coating a 40nm PEDOT: PSS hole transport layer on ITO, spin-coating a polymer donor PTB7-Th of about 100nm and a near infrared receptor micromolecular blending photoactive layer obtained in each example or comparative example respectively, spin-coating an amino polyfluorene quaternary ammonium bromide (PFN-Br) of about 5nm as a cathode interface layer, and evaporating a 100nm Ag layer to prepare the device. The structural formula of PTB7-Th is shown in FIG. 1.
The organic photoelectric detector comprises a transparent conductive anode, an anode interface layer, a polymer donor/micromolecular acceptor active layer, a cathode interface layer and a cathode from bottom to top. The resulting device structure is shown in fig. 2. EQE and dark current measurements at 0V bias were performed on the above organic photodetectors and corresponding responsivity R and detection rate D were calculated, with specific performance parameters as shown in table 1. The responsivity R is the ratio of the photocurrent of the photoelectric detector to the incident light intensity, the unit is A/W, and the calculation formula of R is as follows:
where EQE is directly proportional to R, both reflecting the efficiency of photon to electron conversion. The detection rate D is defined as the inverse of the Noise Equivalent Power (NEP), which is an indicator for measuring the capability of the detector to detect the minimum incident light signal, and the unit is Jones, where the calculation formula of D is as follows:
wherein R is responsivity, q is charge, J d Is dark current.
Fig. 3 to 6 show EQEs of several of the resulting front-mounted organic photodetector devices using all of the near infrared receptor small molecules obtained in examples and comparative examples as the receptor material and PTB7-Th as the donor material, respectively.
Fig. 7 to 8 show responsivity of several of the resulting front-mounted organic photodetector devices using all of the near infrared acceptor small molecules obtained in examples and comparative examples as acceptor materials, PTB7 to Th as donor materials, respectively. The device data obtained are shown in table 1.
TABLE 1 device parameters at 1100nm for organic photodetectors with near infrared receptor small molecules PTB7-Th as active layer at 0V bias in test example 1
Table 2 shows the response parameters of the near infrared receptor small molecules of the specific examples and comparative examples applied to an organic photodetector to a 1050nm LED.
TABLE 2 response parameters of organic photodetectors with near infrared receptor small molecules PTB7-Th as active layer at 0V bias to 1050nm LEDs in test example 1
The above data demonstrate that the detection range of small molecules of non-fullerene receptors of a-D-a structure that does not contain an intrinsic quinoid Q unit is within 1100nm. While non-fullerene acceptor small molecules with similar structures A-D-A-D-A, but whose core structures cannot form intrinsic quinoid Q units, can achieve EQE response spectra exceeding 1100nm, the EQE response at 1100nm is only about 1% at 0V bias. Whereas non-fullerene receptor small molecules based on intrinsic quinoid Q units can achieve high EQE responses of over 16% at 1100nm, indicating that the introduction of intrinsic quinoid Q units is an effective method of inventing high performance near infrared modular non-fullerene receptor small molecules.
