The synthesis and characterization of low-molecular-weight
phthalocyanines using dicyano derivatives synthesized
by a coupling reaction are described. Furthermore, the dicyano
compounds were oxidatively coupled by photoirradiation to synthesize dicyano compounds with extended conjugations. Synthesis of
Pcs was carried out continuously, and the formation of Pcs was confirmed by
MALDI-MS and UV-vis measurements. MALDI-MS spectra of Pcs also indicated the
formation of phthalocyanines with extended conjugations, and UV-vis
measurements revealed a long wavelength shift in the Soret
and Q bands.
Keywords: low-molecular-weight phthalocyanines,
