The temperature dependences of the lifetimes and the efficiency of singlet oxygen generation for a set of compounds (porphyrins, metalloporphyrins, porphycene, terrylene etc.) has been measured and characterized. Based on the character of the temperature dependence of singlet oxygen generation for metalloporphyrins and porphycene it was assumed a possibility of creation a complex between organic moieties and molecular oxygen. Singlet oxygen generation of terrylene with the quantum yield of 22% was recorded in toluene at ambient temperature.
