Unsym. tetrapyrazinoporphyrazines (TPyzPzs) from the group of azaphthalocyanines with one peripherally attached amino substituent (donor) were synthesized, and their photophys. properties (fluorescence quantum yield and singlet oxygen quantum yield) were determined The synthesized TPyzPzs were expected to undergo intramol. charge transfer (ICT) as the main pathway for deactivating their excited states. Several structural factors play a critical role in ICT efficiency. The substituent in the ortho position to the donor center significantly influences the ICT, with tert-butylsulfanyl and butoxy substituents inducing the strongest ICTs, whereas chloro, Me, Ph, and hydrogen substituents in this position reduce the efficiency. The strength of the donor pos. influences the ICT efficiency and correlates well with the oxidation potential of the amines used as the substituents on the TPyzPz as follows: n-butylamine < N,N-diethylamine < aniline < phenothiazine. The ICT (with conjugated donors and acceptors) in the TPyzPz also proved to be much stronger than a photoinduced electron transfer in which the donor and the acceptor are connected through an aliphatic linker.
