具有四个磺酸根基团的水溶性三阴离子杂配型铜（I）光敏剂（CuPS 3-）被发现在水介质中与二阳离子烷基铵（六烃季铵）阳离子（HM 2+）形成1：2离子对加合物，由于光激发态的水衍生非辐射衰减的显著抑制，导致表现出优异的光物理和光催化性能。
A water‐soluble trianionic heteroleptic copper(I) photosensitizer having four sulfonate groups (CuPS3−) was found to afford the 1 : 2 ion‐pair adduct with dicationic alkylammonium (hexamethonium) cations (HM2+) in aqueous media, leading to exhibit excellent photophysical and photocatalytic performances owing to the substantial suppression of water‐derived non‐radiative decay of the photoexcited state.
