Dyads and triads containing perylenetetracarboxylic diimide and porphyrin: Efficient photoinduced electron transfer elicited via both excited singlet
Article Abstract:
The synthesis, characterization and photophysical properties of new photoactive dyads and triads of porphyrin-PIm systems that would be applied to improve the light absorption efficiency and achieve the efficient charge-separation states for appropriately long times is reported. The steady state, time-resolved emission and transient absorption results revealed the occurrence of electron transfer mainly from the porphyrin to perylene entities in the polar solvent.

Design, syntheses, and studies of supramolecular porphyrin-fullerene conjugates, using bis-18-crown-6 appended porphyrins and pyridine or alkyl ammonium functionalized fullerenes
Article Abstract:
Photoinduced electron-transfer processes in cis and trans functionalized bis-18-crown-6 porphyrin self-assembled with fullerene functionalized with pyridine or alkylammonium cation entities are reported. The conjugates revealed stable 'two-point' binding involving metal-ligand coordination and alkylammonium cation-crown ether binding or only the later type of binding depending upon the functionality of the fullerence and metal ion in the porphyrin cavity.

Photoinduced electron transfer from oligothiophenes/polythiophene to fullerenes (C60/C70) in solution: comprehensive study by nanosecond laser flash photolysis method
Article Abstract:
A comprehensive laser flash photolysis study on photoinduced electron transfers both via excited fullerenes and excited ligothiphene/polythiphene in solution by selective excitation using laser light at various wavelengths is conducted. Smaller electron-transfer yields of longer oligomers indicate the contribution of other deactivation processes such as energy transfers.
