技术领域
本发明涉及一类具有荧光功能的有机小分子,具体涉及一类新型的噻唑[4,5-e]噻吩[2,3-b]吡啶类衍生物及其制备方法,它们同时具有强的液体荧光和固体荧光。
背景技术
大约50%的有机化合物在结构上属于杂环化合物(Palwinder Singh.ExpertOpin.Ther.Pat.2011,21(4):437-454),由于杂环化合物的结构独特,是近年来开发新型有机光电材料的基本骨架(Angew Chem Int Ed Engl 2014,53(9):2290-310)。因此,设计、合成结构新颖的杂环化合物并研究它们在材料科学特别是有机发光材料方面的应用具有重要的科学意义和应用价值(Acc Chem Res 2012,45(8):1278-93)。
作为传统的有机小分子发光材料,吩噻嗪类化合物呈现蝴蝶型构型,在太阳能敏化电池(Eur.J.Org.Chem.2014,32:7069-7086)、锂离子电池(J.Phys.Chem.C 2014,118(27):14824-14832)、光催化产氢(J.Mater.Chem.A 2014,2(32):12952-12961)、非线性光学材(Chem.-Eur.J.2008,14(8):2602-2614)、延迟荧光材料(Angew Chem Int Ed Engl2015,54(3):874-8)、有机发光二极管(Angew.Chem.Int.Ed.2014,53(8):2119-23)、聚合物发光二极管(Chem.-Eur.J.2008,14(8):2602-2614)、分子线(J.Am.Chem.Soc.2005,127(33):11842-11850)等方面获得了独特的应用(染料与染色2010,47(3):35-41)。另一类重要的吖啶类化合物,具有π共轭的平面结构,在染料、荧光探针及发光二极管等有机发光材料领域也有重要作用(WO2013093481A1,2013;J.Lumin.2013,139:16-21;Dyes Pigm.2014,109:169-174;Adv.Opt.Mater.2014,2(9):892-901)。近年来报道的噻咯类化合物(Chem.Commun.2001,(18):1740-1741),四苯乙烯类化合物(J.Mater.Chem.2012,22(15):7515-7528;J.Mater.Chem.C 2015,3(11):2624-2631;Chem.Sci.2015,6(3):1932-1937;Chem.-Eur.J.2014,20(18):5317-5326),三芳胺类化合物(Aust.J.Chem.2012,65(4):387-394;Chem.-Eur.J.2011,17(9):2647-2655;Chem.Commun.2010,46(26):4689-4691),都具有良好的聚集诱导发光(AIE)性能,在有机发光二极管、化学传感器、生物传感器等方面具有良好的应用前景。
最近,本课题组通过重排反应,开发了一种新型的噻唑[4,5-e]噻吩[2,3-b]吡啶类化合物的合成方法(Synthesis 2014,46,2317-2326.)。通过对噻唑[4,5-e]噻吩[2,3-b]吡啶类化合物进行结构改造,得到一系列具有新型骨架结构的具有荧光功能的有机小分子,并且该类型的有机小分子发光材料未见文献报道。
