All samples in oxygen free dichloromethane (DCM). Optical densities (ODs) were in the range of 0.12 (C60, 355 nm), 0.14 ([Cu(phen)2]+ complex, 320 nm) and 0.4 (ZnP, 420 nm).
λmax = emission maximum; τ = fluorescence lifetime; Φ = fluorescence quantum yield; E00 = the energy of the corresponding excited state relative to the ground state, calculated from the emission maxima (λmax).
