A series of new porphyrazines with oligo(ethylene oxide) thioalkoxy side chains has been synthesized. Study of the phase transitions reveals the absence of liquid crystallinity. Due to the ethylene oxide moieties, the solubility in a variety of solvents is dramatically increased. This allowed the first study of solvent effects on the photophysical properties (absorption and emission) in water and chloroform. The complexation of the porphyrazines with the redox couple LiI / I 2 has been studied. No effect on the aggregate formation has been observed in solution, while in a film incorporation of an increased amount of LiI / I 2 leads to a disturbance of the aggregates. At temperatures up to 100°C the porphyrazine - LiI / I 2 complexes are stable in the liquid phase, but from 115°C onwards, small crystallites of LiI are formed in the isotropic liquid.
