Abstract(s)The interaction of chloroaluminium phthalocyanine and aluminium porphyrin in solution was studied using UV–visible and fluorescence techniques. The spectra of the porphyrin alone exhibited new bands attributed to aggregates and a value of -12.6 kJ mol-1 for the enthalpy of dimerization was obtained. A small dimerization constant of 5.8 x 103 M-1 was found for phthalocyanine homodimers and preferential formation of mixed dimers over porphyrin homodimers was observed experimentally and supported by molecular modelling. kd and ΔH values of 5.7 x 104 M-1 and -21.1 kJ mol-1 were found in the mixed system, along with an enhancement in phthalocyanine fluorescence.
