Self-assembled azaphthalocyanine dimers with higher fluorescence and singlet oxygen quantum yields than the corresponding monomers

Abstrakt

The self-assembled J-dimers of diethylamino-substituted metal azaphthalocyanines in noncoordinating solvents were described; the influence of such spatial arrangement to fluorescence and singlet oxygen quantum yields was explained as a sterical inhibition of the photo-induced electron transfer
