Photophysical and photochemical properties of phenolhiazine and Noalkylphenothiazines (alkyl ~ methyl, ethyl, isobutyi, phenyl, benzyl) in acetonitrile were studied by means of nanosecond laser flash photolysis. Transient absorption measurements showed that the excited triplet state, radical cation,

In benzene solution, C60 and C7o interact weakly in the ground state with amines having favourable oxidation potentials. Picosecond time-resolved absorption measurements show that on photoexcilation, the weak complexes undergo charge separation to produce ion pairs which in turn undergo fast geminat
