Abstract

The concept of molecular symmetry was rationally applied to transform a monomeric asymmetric indolizine moiety into a dimeric symmetric bisindolizine, resulting a new fluorescent molecular framework having appealing aggregation induced emission (AIE) properties and a bathochromic shift in emission wavelength. The synthetic protocol utilized an operationally straightforward Pd-catalyzed dehydrogenative coupling reaction. Among the synthesized derivatives, the most efficient AIE compound was identified and employed for latent fingerprint (LFP) imaging. The LFP visualization protocol involves the application of the AIEgen solution to the fingerprint surface, followed by washing with water to reveal detailed fingerprint pattern.

双吲哚嗪：一种新型活性成分及其在指纹潜影成像中的应用

合理运用分子对称的概念，将单体不对称的吲哚嗪片段转化为二聚体对称的双吲哚嗪，得到了一种具有聚集诱导发射（AIE）性能和发射波长变色的新型荧光分子框架。合成方案采用操作简单的pd催化脱氢偶联反应。在合成的衍生物中，鉴定出效率最高的AIE化合物，并将其用于潜在指纹（LFP）成像。LFP可视化方案包括将AIEgen溶液应用于指纹表面，然后用水冲洗以显示详细的指纹图案。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
