Several acetylene bridged porphyrin-monophthalocyaninato ytterbium(iii) hybrids, PZn-PcYb, PH2-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 (1O2) quantum yields and the two-photon absorption cross-section (σ2), were investigated. These three newly synthesized compounds exhibited very large σ2 values and substantial 1O2 quantum yields upon photo-excitation, making them potential candidates as one- and two-photon photodynamic therapeutic agents.
