In recent decades, the traceless nature of visible photons has been exploited for the development of efficient synthetic strategies for the photoconversion of colourless compounds, namely, photocatalysis, chromophore activation, and the formation of an electron donor/acceptor (EDA) complex. However, the use of photoreactive coloured organic compounds is the optimal strategy to boost visible photons as ideal reagents in synthetic protocols. In view of such premises, the present review aims to provide its readership with a collection of recent photochemical strategies facilitated via direct light absorption by coloured molecules. The protocols have been classified and presented according to the nature of the intermediate/excited state achieved during the transformation.

可见光子作为有色有机化合物活化的理想试剂

近几十年来，人们利用可见光子的无痕性质来开发无色化合物光转化的有效合成策略，即光催化、发色团激活和电子供体/受体（EDA）复合物的形成。然而，使用光反应性有色有机化合物是增强可见光子作为合成方案中理想试剂的最佳策略。鉴于这些前提，本综述旨在为读者提供一系列通过有色分子直接吸收光来促进的最新光化学策略。该协议已根据转换过程中实现的中间/激发状态的性质进行了分类和呈现。
