conventional counterepart, which relies upon condensation of a quaternized benzodipyrrolenine with Fisher's aldehyde, for the synthesis of a symmetrically substituted dyes that contain various heterocyclic end-groups. Investigations of the spectral and luminescent properties of the dyes in solution revealed that the absorption (596–717 nm) and emission (629–773 nm) maxima of the biscyanines were red-shifted
一种新的长波吸收和发射双三甲胺染料的合成新方法是将苯并二吡咯啉二醛与季铵化的杂环CH-酸性化合物缩合,以制备一系列双花菁。该新方法比常规对等方法更方便,该常规对等方法是将季铵化的苯并二吡咯啉与费舍尔醛缩合,以合成包含各种杂环端基的对称取代的染料。对染料在溶液中的光谱和发光特性的研究表明,与母体“单体”花青相比,双花青素的最大吸收(596–717 nm)和最大发射(629–773 nm)红移了约100 nm。仅包含一种发色的聚次甲基系统。-1 cm -1)和量子产率(≤28%)。两个末端苯并恶唑部分均被吲哚啉,苯并噻唑,2-和4-喹啉取代,使吸收和发射最大值出现红移,但降低了量子产率。
