The present manuscript describes the synthesis and the photophysical properties of a pair of novel flavin-pyrene dyads where the donor and the acceptor entities are separated via variable spacer. The dyads were well characterized using standard techniques and investigated for their photophysical and electrochemical nature. The observed absorption spectra of the dyads mainly display peaks corresponding
本手稿描述了一对新型黄素-芘二元体的合成和光物理性质,其中供体和受体实体通过可变间隔基分开。使用标准技术对这对二元体进行了很好的表征,并研究了它们的光物理和电化学性质。观察到的二元组的吸收光谱主要显示对应于各个芘和黄素单元的峰,其中芘区域中的黄素实体有一些贡献。同时,与单个成分相比,两个二元组都观察到强烈的发射猝灭。然而,对发射光谱和溶剂依赖性研究的仔细分析揭示了这两个成对体之间的细微差别。虽然在黄素区域激发时没有观察到显着差异;在紧密连接的二元组的情况下,芘区域的激发显示出弱而宽的发射带。此外,通过循环伏安法研究了电化学性能,观察到还原能力遵循FlPy2 < FlPy1 < Fl的趋势。
