Abstract

A series of dipyrrolopyrazine (DPP) based chromophores featuring thiophene and varied donor (,-dimethylamine, NH, OMe) and acceptor (CF, CN, NO) appendages have been synthesized. The structures and properties of the chromophores were investigated by absorption spectroscopy, electrochemistry, differential scanning calorimetry, and thermogravimetric analysis. X-ray crystallographic analysis indicates a planar geometry for the molecule 7g. Surface morphological studies reveal the formation of microrods and nanorods. The acidochromic behavior of the chromophore which shows a prominent red-shift in the absorption spectra owing to the protonation of the pyrazine segment provides a valuable opportunity to assess the sensory response. Acid dependent spectral changes could be successfully applied to detect pH in biological fluids and acid impurities in solvents.

摘要

已经合成了一系列基于二吡咯并吡嗪（DPP）的发色团，其具有噻吩以及不同的供体（-二甲基胺、NH、OMe）和受体（CF、CN、NO）附属物。通过吸收光谱、电化学、差示扫描量热法和热重分析研究了发色团的结构和性质。X射线晶体学分析表明分子7g具有平面几何结构。表面形态学研究揭示了微棒和纳米棒的形成。发色团的酸致变色行为由于吡嗪片段的质子化而在吸收光谱中显示出明显的红移，这为评估传感响应提供了宝贵的机会。酸依赖性光谱变化可成功应用于检测生物流体中的pH值和溶剂中的酸性杂质。
