Synthesis and properties of C–C conjugated phthalocyanine dimers
摘要:
Covalently C-C linked Pc-Pc homo-dimers (ortho and meta) were synthesized from their corresponding Pc halide precursors using a Pd-catalyzed homo-coupling reaction. Photophysical data reveal energy transfer between the Pc moieties resulting in the appearance of new red-shift Q-bands that correlate to the planarity and dihedral angle between the Subunit.

Phthalocyanines (Pc) were conjugated with peptide moieties to improve their target selectivity for potential use as fluorescence and/or positron emission tomography (PET) probes in medical imaging. Three synthetic methods based on palladium-catalyzed cross-coupling reactions (Sonogashira, Buchwald−Hartwig, and Suzuki−Miyaura) were investigated. Using these methods, a series of peptides monofunctionalized
