Two porphyrin derivatives TPP-AQ and TPP-PD were synthesized and characterized. The physical properties of these two molecules were studied by cyclic voltammetry, ultraviolet visible spectra, fluorescence spectra and theoretical calculations. The redox potentials of TPP-AQ and TPP-PD are 1.07, 1.30 V and 1.21, 1.36 V, respectively. The redox potentials of TPP-AQ are negative-shifted compared with those of TPP-PD. The maximum absorptions of TPP-AQ and TPP-PD are 441 and 431 nm, respectively. The maximum absorption of TPP-AQ was red-shifted compared with that of TPP-PD due to that the conjugated effect of TPP-AQ is greater than that of TPP-PD based on the results of theoretical calculations. The red fluorescence peaks of TPP-AQ and TPP-PD are 657 and 656 nm, and the full widths at half-maximum of TPP-AQ and TPP-PD are 30 and 27 nm.
