Optical and electronic properties of manganese thiophosphate and H2T4 porphyrin metal complexes films

Films of manganese thiophosphate (MnPS3) and Mn(III)T-4 porphyrin, obtained from a reaction of a colloidal suspension of MnPS3 nanosheets with an aqueous solution of the porphyrin, have been investigated by means of optical absorption and X-ray photoemission spectroscopies. Our attention is turned to the (300-850) nm range and to the C and N 1s, Mn, P, S and Cl 2p and Mn 3p core regions. The analysis of the resulting spectra and their comparison with those reported for the original compounds has allowed us to obtain information both about the interaction between MnPS3 and Mn(III)T-4 and the effects produced by the porphyrin metallation.
