Abstract

Photon upconversion based on triplet–triplet annihilation (TTA-UC) is an attractive wavelength conversion with increasing use in organic synthesis in the homogeneous phase; however, this technology has not performed with canonical solid catalysts yet. Herein, a BOPHY dye covalently anchored on silica is successfully used as a sensitizer in a TTA system that efficiently catalyzes Mizoroki–Heck coupling reactions. This procedure has enabled the implementation of in-flow reaction conditions for the synthesis of a variety of aromatic compounds, and mechanistic proof has been obtained by means of transient absorption spectroscopy.

内流异质三重-三重湮没上转换

基于三重-三重湮灭的光子上转换（TTA-UC）是一种极具吸引力的波长转换技术，在均相有机合成中的应用日益广泛。在这里，一种共价锚定在二氧化硅上的 BOPHY 染料被成功地用作 TTA 系统中的敏化剂，从而高效地催化了 Mizoroki-Heck 偶联反应。这一过程实现了在流动反应条件下合成多种芳香族化合物，并通过瞬态吸收光谱获得了机理证明。
