摘要
通过Suzuki交叉偶联反应得到三苯胺和N-苯基咔唑分别取代的1,8-萘酰亚胺衍生物,化合物结构经1HNMR、质谱和元素分析表征。两种材料都是双极分子,存在分子内电荷转移,单线态-三线态能级差分别为0.40和0.32 eV。荧光量子效率和荧光寿命的测试结果表明,两种材料均能发射延迟荧光。
Two derivatives based on triphenylamine and N-phenyl carbazole substituted 1,8-naphthalimide have been synthesized by Suzuki cross-coupling reactions.Structures of the target compounds were confirmed by 1^HNMR,MS and elemental analysis.The two bipolar compounds based on intramolecular charge transfer exhibit small energy gaps between singlet and triplet（ ΔEST） of0. 40 and 0. 32 e V,respectively.The results of fluorescent quantum yields and fluorescent lifetime indicate that two materials could emit delayed fluorescence.
