摘要

我们合成了三种氨基羰基化合物，在不同溶剂极性下记录到的它们的发射光谱行为显示出明显的倒溶氟色性。在中等溶剂极性条件下会出现发射能量倒置，其原因是负责稳定染料高度齐聚激发态的溶液-溶剂相互作用从二极性转变为酸性。

Aminocarbonyl Fluorophores with a Strong Emissive Inverted Solvatochromism

Three aminocarbonyls were synthesized, and their emissive spectral behavior recorded at various solvent polarities showed marked inverted solvatofluorochromism. The emission energy inversion occurs at moderate solvent polarities and was found to be triggered by a change in the solute–solvent interaction responsible for the stabilization of the highly zwitterionic excited state of the dyes, from dipolarity to acidity.

期刊介绍： The Journal of Physical Chemistry (JPC) Letters is devoted to reporting new and original experimental and theoretical basic research of interest to physical chemists, biophysical chemists, chemical physicists, physicists, material scientists, and engineers. An important criterion for acceptance is that the paper reports a significant scientific advance and/or physical insight such that rapid publication is essential. Two issues of JPC Letters are published each month.
