芘衍生物发光行为的研究

本工作合成了新型的芘衍生物-芘基查尔酮(PD), 研究了其在溶液及胶束中的稳态光物理行为。结果表明: 即使在较低浓度条件下, PD分子间也容易生成基态电荷转移配合物(Inter-CT), 其荧光光谱表现为芘单体荧光、分子内电荷转移态(Intra-CT)荧光以及Inter-CT荧光, 并且具有较好的溶致变色效应、浓度效应以及温度效应, 是一良好的探针分子化合物。

A study on the fluorescence emitting properties of pyrene derivative

In this work, a new pyrene derivative pyrenyl chalaone (PD) has been synthesized and its steady-state photophysical properties in solution and micell systems have been studied. Results indicated that the intermolecular charge transfer complexes (Inter-CT) between PD molecules are very easy to form even if the concentration is very low. The fluorescence emission of PD comprises the fluorescences from pyrenyl monomer, intramolecular charge transfer state (Intra-CT) and intermolecular charge transfer state complex. The compound PD has good solvatochromism effect, concentration effect and temperature effect, and is a better probe molecule for microenvironment.
