Resumen

Combining the effects of heavy atom and low temperature, the phosphorescence spectrum from 1H-phenalen-1-one has been unveiled. The 0-0 band is located at 649 nm in methylcyclohexane and shifted to 646 nm in ethanol, which sets the triplet-energy level to 185 and 186 kJ·mol-1, respectively. The emission is unambiguously identified as phosphorescence originating from 1H-phenalen-1-one through complementary transient absorption and emission studies. The quantum yield for triplet formation is confirmed to be unity.
