摘要:
A phthalocyanine derivative containing two-photon chromophores which are based on pyrimidine was designed and synthesized. Its light-emission property was studied in detail, and a strong energy transfer from peripheral chromophores to the phthalocyanine core was observed. The compound exhibited strong two-photon absorption responses with a two-photon absorption cross-section up to 1153 GM when irradiated with a picosecond laser in the wavelength range of 800-870 nm, and gave good singlet oxygen generation.
