novel materials, 10-(6-(dibenzo[b,d]furan-1-yl)pyrazin-2-yl)-9,9-diphenyl-9,10-dihydroacridine (PrFPhAc) and 10-(6-(dibenzo[b,d]thiophen-1-yl)pyrazin-2-yl)-9,9-diphenyl-9,10-dihydroacridine (PrTPhAc), were designed and synthesized by introducing heterocyclic pyrazine between 9,10-dihydroacridine and dibenzofuran/dibenzothiophene moieties. The basic properties, such as thermal, photophysical and electrochemical
两种新颖的材料10-(6-(二苯并[ b,d ]呋喃-1-基)吡嗪-2-基)-9,9-二苯基-9,10-二氢ac啶(PrFPhAc)和10-(6-(通过在9,10-二氢ac啶与二苯并呋喃之间引入杂环吡嗪来设计合成二苯并[ b,d ]噻吩-1-基)吡嗪-2-基)-9,9-二苯基-9,10-二氢ac啶(PrTPhAc)。 /二苯并噻吩部分。系统地研究和比较了基本性质,例如热,光物理和电化学性质。两种材料都具有适用于红色磷光有机发光二极管的三重态能量,并且最终以22%的出色外部量子效率获得了二苯并呋喃(DBF)衍生物PrFPhAc。
