Abstract

Several acetylene bridged porphyrin-monophthalocyaninato ytterbium(iii) hybrids, PZn-PcYb, PH ₂-PcYb and PPd-PcYb, have been prepared and characterized by ¹H and ³¹P NMR, mass spectrometry, and UV-vis spectroscopy. Their photophysical and photochemical properties, especially the relative singlet oxygen ( ¹O ₂) quantum yields and the two-photon absorption cross-section (σ ₂), were investigated. These three newly synthesized compounds exhibited very large σ ₂ values and substantial ¹O ₂ quantum yields upon photo-excitation, making them potential candidates as one- and two-photon photodynamic therapeutic agents.
