文摘
Zn and Pd complexes of meso-tetraphenyltetranaphthaloporphyrins(Ph4TNP) exhibit strong infrared absorption bands and luminescein solutions at room temperature. S1 
S0 fluorescence (
max =732 nm, 
= 5.3%) is the predominant emission in the case ofZnPh4TNP (1). This emission is in part due to the delayedfluorescence ( = 1.1%). Phosphorescence (T1 S0) of 1 (max= 973 nm) is very weak ( = 0.04%) and occurs with lifetime ofabout 440 
s in deoxygenated DMF. In the case of PdPh4TNP(2), almost no S1 S0 fluorescence could be observed, whilethe main emission detected was T1 S0 phosphorescence (max= 938 nm). The phosphorescence of 2 occurs with lifetime ofabout 65 s and (=6.5%) in deoxygenated DMF solution.Metalloporphyrins 1 and 2 are promising near infrared dyesbiomedical applications.
