摘要: Abstract The effects of meso-substituents and porphyrin core-modification on electronic communication between ferrocene in covalently linked porphyrin–ferrocene conjugates are described. electrochemical photophysical studies indicated that the is strong when five membered aryl groups than six groups. This may be traced to near orthogonal arrangement ring with meso-aryl leading weaker interaction ferrocenyl conjugates, while furyl thienyl closer plane being orthogonal. Molecular orbital performed at semiempirical PM3 BLYP levels rationalize results.
