A series of novel tetra-meso-thien-2-yl porphyrins were synthesised, and the effect variation in thienyl group on photophysical properties studied. Ground excited state UV–vis absorption, steady-state time-resolved emission, resonance Raman spectroscopy, cyclic voltammetry, used to establish extent electronic communication between central Zn(II) porphyrin ring various meso-substituent groups. T...

An N-fused porphyrin rhenium complex was synthesized by the thermal reaction of an N-confused porphyrin with Re2(CO)10 and its structure was determined by X-ray crystallographic analysis.

We report the spectroscopic changes of tetraphenylporphyrin carbon nanotube composites in a variety of chlorinated solvents such as chloroform, dichloroethane and dichlorobenzene as a result of sonication. Detailed data analysis suggests that protonation of the porphyrin core nitrogen atoms occurs as a result of sonodegradation of the solvent molecules. Extreme care must be taken when working w...
