Photoinduced cleavage of the carbon-indium bond in ethylindium(III) tetraphenylporphyrin
The photochemistry of ethylindium(III) tetraphenylporphyrin, C/sub 2/H/sub 5/In/sup III/TPP, in benzene solutions was studied by steady light and laser flash photolysis. From the analysis of the products, the C/sub 2/H/sub 5/-In bond in C/sub 2/H/sub 5/In/sup III/TPP was confirmed to be photodissociated. The quantum yields for the photodecomposition of C/sub 2/H/sub 5/In/sup III/TPP were found to be diminished by the addition of ferrocene. However, 2,4,7-trinitro-9-fluorenone, a strong electron acceptor, was found to increase the quantum yields. The laser photolysis studies revealed that the photoreaction of C/sub 7/H/sub 5/In/sup III/TPP occurs via the triplet state originating from the porphyrin ligand.
