摘要
在电子传输发光单元(1,8-萘酰亚胺)中引入空穴传输单元(苯并噻唑、苯并噁唑、苯并咪唑),采用分子扭曲设计,合成了9个具有分子扭曲构型的萘酰亚胺衍生物,并对其电化学性能、光谱性能和热稳定性能进行了测试.所合成的衍生物具有较高的量子产率和很好的热稳定性,荧光寿命在10 ns左右,呈黄绿光,可作为发光材料应用在有机电致发光器件中.
A new family of twisted intramolecular luminescent materials containing electron-transporting and emitting unit （1,8-naphthalimide） and hole-transporting unit （benzothiazole, benzoxazole, benzimidazole） were synthesized. The electrochemical, UV-visible spectroscopic properties and thermally stability of these derivatives were measured. The results indicate that these compounds emit intense yellow fluorescence with appropriate lifetimes, high quantum yield and thermally stability, useful luminescent materials in OLEDs.
