- Abstract
- We successfully synthesized non-aggregated silicon (IV) tetrapyrazinoporphyrazines (SiPz) bearing bornane groups at their peripheral positions. The UV-vis spectra of the SiPz complexes maintained a strong and sharp Q-band, which is an archetypal characteristic of non-aggregated phthalocyanines, in various organic solvents. In addition, the extreme red emission of SiPz complexes 4a-4c under visible light in a neutral solution condition was observed. However, the SiPz complex (4d) with axial aniline groups had very low fluorescence quantum yields due to the quenching ability of the aniline group.
