A novel zinc(II) phthalocyanine-chlorambucil conjugate (7) has been synthesized by treating an amino-mono-substituted zinc(II) phthalocyanine with chlorambucil, followed by characterization with 1H NMR and HRMS. Its photophyscial and photochemical properties has been investigated. The results indicate that it remains in the form of monoer and show a relative high singlet oxygen quantum yield in DMF, but exhibits a aggregation trend with a weaker and broadened Q band in aqueous solution ( PBS with 0.1% Cremophor EL), which also caused the reduction of fluorescence emission. In addition, after conjugating with chlorambucil, the generation of singlet oxygen of phthalocyanine decreased.

Keywords:PDT; Phthalocyanine-CLB conjugate; Synthesis; Spectroscopy properties
