We investigated how the positional arrangement of electron-donating (amino) and electron-withdrawing (ester) groups in single benzene-based fluorophores influences their emission properties. By synthesizing 26 regioisomeric fluorophores, we achieved wavelength modulation from 322 to 539 nm, revealing key correlations between functional group positioning and photophysical behavior.

供电子基团和撤离基团的位置效应对单苯荧光团光物理性质的影响


我们研究了单个苯基荧光团中供电子（氨基）和吸电子（酯）基团的位置排列如何影响其发射特性。通过合成 26 个区域异构荧光团，我们实现了从 322 到 539 nm 的波长调制，揭示了官能团定位和光物理行为之间的关键相关性。
