本研究发现，吸电子基团（如砜基）的负诱导效应可以明显提高氨基氧化色素的电离势，从而有效抑制分子内扭曲电荷转移（TICT），显著提高水溶液中几种荧光基团的量子产率。
Herein, we present that the negative inductive effect exerted by electron-withdrawing groups, such as sulfone groups, can obviously improve the ionization potential of amino auxochromes, thereby effectively inhibiting twisted intramolecular charge transfer (TICT) and markedly improving the quantum yields of several families of fluorophores in aqueous solution.
