Spectral sensitization of TiO2 substrates by monolayers of porphyrin heterodimers

Article Abstract:

Research is presented concerning an investigation of the effect of combining a charge-transporting, supersensitizing molecular antenna with a charge injecting layer in order to increase organic solar cell photocurrent yields. Absorption spectra and photocurrent action spectra are observed.

Comparative study of the photophysical properties of nonplanar tetraphenylporphyrin and octaethylporphyrin diacids

Article Abstract:

The photophysical properties of the lowest excited singlet states, S1(Pi,Pi*), of two porphyrin diacids are investigated. It is explained that the funnels involve configuration at which the potential-energy surfaces of the ground and excited states approach more closely than at the equilibrium excited-state structure(s) from which steady-state fluorescence occurs.

Spectroscopy and photo physics of self-organized zinc porphyrin nanolayers. 1. Optical spectroscopy of excitonic interactions involving the soret band

Article Abstract:

Excitonic interactions in the second excited singlet state of zinc tetra-(p-octylphenyl)-porphyrin (ZnTOPP) reported the spectroscopic and photo physical properties of first and second excited singlet states as well as the lowest excited triplet state in 5-25nm-thick, self-organised films of porphyrin on quartz slides and the effect of various solvents and temperature annealing on their degree of order. The absorption spectra were insensitive to atmospheric moisture, in contrast to zinc tetraphenylporphyrin films
