6,7‐Bis[3‐( N ϵ ‐ tert ‐butyloxycarbonyllysine methyl ester)]‐1,3,5,8‐tetramethyl‐2,4‐divinylporphyrin ( 3 ) was synthesized and successfully immobilized in a silica matrix by a sol–gel method. Protoporphyrin (PP)‐derived amide 3 showed much higher photostability than its parent PP‐IX. Its UV/Vis absorption, excitation, and fluorescence spectra as well as its ability to generate 1 O 2 were measured both in solution and in the matrix. Subsequently, free and immobilized porphyrins 3 were used as sensitizers in the photooxidation of α‐pinene, and their photocatalytic properties were compared.
