Description
Technical field
The present invention relates to the electroluminescent organic material technical field, particularly class substituted quinoline trimer indene derivative and preparation method thereof.
Background technology
Traditional photoelectric functional material mainly is metal, metalloid and some oxide compounds, and how organic compound does not possess unbound electron owing to its constructional feature, thereby has no chance with functions such as light, electricity, magnetic for a long time.Flourish along with the optoelectronic information industry constantly proposed new higher level requirement to material, and over nearly two, 30 years, people have also showed keen interest to the photoelectric properties of organic compound.Since the seventies, people have successively found organic conductor, organic superconductor, Organic Ferromagnet, organic non linear optical material etc., explore at theory research and material and have showed brilliant prospect aspect two.
Organic electroluminescent also is Organic Light Emitting Diode (OLED), is one of the flat pannel display field to study focus ([1] Tang, C.W greatly in the world in recent years; Van Slyke S.A.Appl.Phys.Lett.1987,51,91; [2] Muller C.D., Falcou A., Reckefuss N.et al.Nature, 2003,421,829.), advantage such as have panelized, active illuminating, brightness height, high-contrast, response speed is fast, driving voltage is low and be considered to a kind of new technology ([3] Teng Feng, Hou Yanbing, the seal Shou Gen etc. of following most possible replacement liquid crystal display, electroluminescent organic material and use in May, 2006, Chemical Industry Press).The application of technique of display in the modern life also more and more widely, as mobile phone screen, instrument display screen, computer terminal indicating meter, televisor and outdoor large screen display screen etc.Therefore, no matter still from a business perspective from scientific and technological angle, the novel high-performance technique of display all can become the research focus in technique of display field in the world, therefore cause the very big concern of people, explore and study the heat subject that novel luminous organic material has just become research field electroluminescent organic material and electroluminescent device.
Three polyindenes are highly symmetric condensed-nuclei aromaticss, have been proved to be one of idealized compound for preparing liquid crystal material, fullerene derivate and C3 type asymmetry catalysis material etc.If three polyindenes can be carried out suitable chemically modified, and construct novel organic conjugate functional materials, will produce unique optics and photoelectron behavior as structural motif.
Biological organic organic solid and the macromolecular material research department that leads with doctor Pei Jian of key lab of the molecular engineering the Ministry of Education of Chemical and Molecular Engineering College of Beijing Univ., first three polyindene structures are introduced the organic photoelectrical material field, they utilize three polyindenes as structural motif, have successfully prepared a trimer indene derivative that a series of starlike oligo-thiophenes replace and a class novel conjugated dendritic macromole ([4] J.Pei, the J-L Wang based on three polyindene structures, X-Y.Cao, X-H Zhou, W-B.Zhang, J.Am Chem.Soc.2003,125, p9944-9945.[5] X.Y Cao, W.-B.Zhang, J.-L.Wang, X.H Zhou, J.Pei, J.Am.Chem.Soc.2003,12340-12341.[6] S.-C.Yuan, H.-B.Chen, Y.Zhang, J.Pei, Org.Lett.2006,8,5701-5704.).This achievement broken through traditional with simple molecules such as benzene, fluorenes, thiophene phenylenevinylenes as the limitation of constructing primitive, provide a kind of brand-new thinking for constructing novel organic conjugate functional materials.
The trimer indene derivative that the starlike oligo-thiophenes of this study group's synthetic replaces is along with the progressively growth of thiophene arm, the ultraviolet of compound and absorption spectrum be red shift thereupon all, not only good restraining the p synergistic effect between the aromatic ring plane, improve simultaneously institute's synthetic material well at solid-state pattern down, had the very optical property of excellence.This type of material is quite optimistic as the prospect of organic electroluminescent diode apparatus and organic solar batteries.
Summary of the invention
