Abstract

We developed a simple and rapid process for synthesizing dithieno[3',2':3,4; 2'',3'':5,6]benzo[1,2-c][1,2,5]thiadiazole (fDTBT) derivatives using crystalline sulfur and internal alkynes, wherein thiophene is cyclized to benzothiadiazole. Cyclized derivatives were synthesized in three or five steps using this reaction, whereas the conventional synthesis methods involved seven steps and hazardous reactions with explosive properties. The absorption spectra of the synthesized fDTBT derivatives in chloroform solution revealed a new absorption band owing to the cyclization. All three compounds exhibited orange-to-red luminescence, and the maximum absolute quantum yield was determined to be 67%, demonstrating excellent luminescence.
具有 fDTBT 衍生物的发光 π 共轭材料的简单合成方法
我们开发了一种简单快速的工艺,利用结晶硫和内部炔烃合成二噻吩并[3',2':3,4; 2'',3'':5,6]苯并[1,2-c][1,2,5]噻二唑(fDTBT)衍生物,其中噻吩环化为苯并噻二唑。利用该反应只需三到五个步骤就能合成环化衍生物,而传统的合成方法需要七个步骤,且反应具有爆炸危险性。合成的 fDTBT 衍生物在氯仿溶液中的吸收光谱显示,由于环化作用,出现了一个新的吸收带。这三种化合物都发出橙红色的荧光,其最大绝对量子产率为 67%,显示出卓越的发光性能。
