Abstract

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.

供电子基团和取电子基团对单苯类荧光团光物理性质的位置效应。
我们研究了单个苯基荧光团中的供电子(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 种 Regioisomeric 荧光团,我们实现了从 322 纳米到 539 纳米的波长调制,揭示了官能团定位与光物理行为之间的关键关联。
