Laser-induced triplet excitons in the columnar crystalline and liquid-crystalline phases of an octasubstituted zinc phthalocyanine have been studied by nanosecond absorption spectroscopy. For low-energy excitation, exponential decay kinetics are obtained; the triplet lifetime is phase dependent (r=2

Octakis(alkoxymethyl) cobalt phthalocyanines with relatively short side chains were synthesized which exhibited no thermotropic liquid crystalline behaviour. The final products as well as the intermediates have been characterized by proton magnetic resonance, infrared and electron spectra and elemen
