abstractphotoredox chemical reactions induced by visible light have undergone a renaissance in recent years . 
 polypyridyl dyes such as ir(ppy)3 and ru(bpy)3 are key catalysts in this event , and blue or whitelight irradiation is required for the chemical transformations . 
 however , it remains a challenge to achieve reactions under the lower energy of red light . 
 we disclose , herein , that trifluoroethoxycoated subphthalocyanine realizes the redlightdriven trifluoromethylation of alkenes and alkynes with trifluoromethyl iodide in goodtohigh yields . 
 perfluoroalkylations were also achieved under red light . 
 the reaction mechanism is discussed with the support of uv / vis spectroscopy and cyclic voltammetry of trifluoroethoxycoated subphthalocyanine . 
 light irradiation / dark study also supports the proposed mechanism .
