Abstract
The absorption and fluorescence properties of a series of substituted dodecaphenylporphrins in dichloromethane are reported, The structures calculated using molecular mechanics reveal that there exist similar c onformations independent of the substituents at meso-phenyl rings. The electronic effect of the peripheral substituents is responsible for t he spectral redshift and the reduced lifetimes. (C) 1998 Elsevier Scie nce B.V. All rights reserved.
