摘要

采用一步缩合法设计合成了六种2-噻吩甲醛缩氨基硫脲类小分子化合物

这类化合物在固态下具有蓝色发光性能

可潜在应用于有机发光二极管三基色的蓝色发光材料中.利用稳态荧光发射光谱研究了不同取代基对2-噻吩甲醛缩氨基硫脲衍生物荧光发射峰位、荧光量子产率以及荧光寿命的影响.选取荧光性能较好的2-噻吩甲醛缩苯基氨基硫脲为活性物质制备了聚苯乙烯薄膜

此薄膜与化合物粉末具有相同的荧光性能

为此类化合物在装饰及防伪领域的应用提供了参考价值.

Abstract

Six 2-thiophenecarboxaldehyde thiosemicarbazone derivatives were designed and synthesized by the one-step condensation. These compounds exhibit blue ?uorescence in the solid-state

which can be used as a blue light-emitting material in the organic light-emitting diodes.The effects of different substituents on the ?uorescence emission peak position

?uorescence quantum yield and ?uorescence lifetime of 2-thiophenecarboxaldehyde thiosemicarbazone derivatives were investigated by the steady-state ?uorescence emission spectra. A new composite ?lm with 2-thiopheneformaldehyde phenylthiosemicarbazone/polystyrene was prepared

which has the similar?uorescence properties as the powder. There results provide a reference value for such compounds in decorative and anti-counterfeiting applications.
