Spectroscopic studies on monomers and dimers of thiaporphyrins

Intramolecular energy transfer dynamics in differently linked zinc porphyrin–dithiaporphyrin dyads

Intramolecular energy transfer dynamics in two molecular dyads, in which zinc porphyrin and dithiaporphyrin units were linked covalently, were studied by ultrafast time-resolved transient absorption and fluorescence spectroscopic techniques.

The origin of the absorption spectra of porphyrin N- and dithiaporphyrin S-oxides in their neutral and protonated states

DFT, TDDFT, and SCS-CC2 calculations were used to investigate the excited states of the NIR absorbing neutral and protonated forms of a dithiaporphyrin S-oxide and a porphyrin N-oxide.
