Axially substituted silicon (IV) tetrapyrazinoporphyrazines: Synthesis, characterization and investigation of photophysicochemical properties
چکیده انگلیسی
A series of silicon tetrapyrazinoporphyrazine (SiPz) complexes, conjugated with various substituents at their axial positions, were synthesized into non-aggregated structures in organic solvents. The UV-vis spectra of the SiPz complexes maintained a strong and sharp Q-band, which is an archetypal characteristic of non-aggregated phthalocyanines (Pcs), in various organic solvents under high concentrations. In addition, the SiPz complexes with axial alkyl groups had high fluorescence quantum yields and singlet oxygen quantum yields. However, the SiPz complexes with axial aniline groups had very low fluorescence quantum yields and singlet oxygen quantum yields due to the quenching ability of the aniline group.
