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.
