We report here the synthesis, X-ray structures, optical and electrochemical properties, fabrication of light-emitting devices, and density functional calculations for indolizino[3,4,5-ab]isoindole (INI) derivatives. Strongly luminescent heterocycles based on the INI unit were synthesized by 1,3-dipolar cycloaddition reactions between pyrido[2,1-a]isoindole (PIS) and acetylene or ethylene derivatives
我们在此报告了吲哚嗪 [3,4,5-ab] 异吲哚 (INI) 衍生物的合成、X 射线结构、光学和电化学特性、发光器件的制造和密度泛函计算。基于 INI 单元的强发光杂环是通过吡啶并 [2,1-a] 异吲哚 (PIS) 和乙炔或乙烯衍生物之间的 1,3-偶极环加成反应合成的。它们是吲哚并[3,4,5-ab]异吲哚2-9和14-15,苯并[1',2'-1,2]吲哚并[3,4,5-ab]异吲哚10,哒嗪[4' ,5':1,2]indolizino[3,4,5-ab]isoindoles 12-13, and 2,3-hydropyridazino[4',5':1,2]indolizino[3,4,5-ab] isoindole-1,4-dione 11.相对发光量子产率可高达90%。它们的还原和氧化电位以及高发光度可以使这些杂环成为三(8-羟基喹啉)铝(Alq(3))的替代品。发光器件的亮度高达
