Abstract
Copper porphyrins emit from the lowest excited porphyrin (π, π*) triplet state even at room temperature. An unpaired electron in the metal dx2−y2 orbital interacts with porphyrin w electron system. Due to this interaction, emission from the lowest excited (π, π*) singlet state is quenched by prompt intersystem crossing and “phosphorescence” is observed with a 10~100 ns lifetime in toluene at 300 K.
