摘要: 合成了两个N,N′-取代的靛蓝染料,反式-N,N′-双对硝基苯甲酰基靛蓝(1)和反式N,N′-双间硝基苯甲酰基靛蓝(Ⅱ)。研究了这两个染料与电子给体(胺类化合物)或与电子受体(紫精化合物)之间的电子转移。结果表明,这两个染料在激发单重态经荧光猝灭,被紫精猝灭的速度常数(kq)比被胺猝灭的速度常数大。

Abstract: Two N, N’-disubstituted indigo dyes, trans-bis-(4-nitrobenzoyl) indigo and trans-bis-(3-nitrobenzoyl) indigo, were synthesized and the electron transfers between two dyes and electron donors (amine compounds) or electron acceptor (viologen compound) were studied in polar solvent. The experimental investigation shows that these two dyes undergo fluorescence quenching in their singlet excited state and the quenching rates (Kq) by viologen are faster than that by amines.

Key words: N,N’-disubstituted indigo dye. electron transfer, electron donor and electron acceptor, fluorescence quenching, photosensitizer
