Zinc perfluoro-fluoroalkyl-phthalocyanine, synthesized in high yield, does not exhibit electron loss, does not aggregate in solution, is photostable and produces 1O2 in very high quantum yields. Aerobic photo-oxygenation of an external substrate occurs without catalyst self-oxidation. The encapsulation of a metal center in a refractory organic environment could guide the design of other viable catalysts for oxygenation of substrates either for synthesis or for oxidative destruction of organic or biological molecules, under reaction conditions that include the use of only air and light.

singlet oxygen reactivity of the first representatives of Group III perfluoroalkyl perfluoro metal phthalocyanines, gallium and indium complexes. Microwave-assisted synthesis was used to produce F[Formula: see text]PcM, M [Formula: see text] Ga, In in reasonable yields. Both Ga and In complexes exhibit high thermal and chemical stability properties, attributed to the perfluoroalkyl perfluoro phthalocyanine

moiety diminishes the fluorescence efficiency of 5, relative to 3, but for singlet oxygen (1O2) generation, photochemical hydroperoxidation of β-(−)-citronellol using 5 and 3 occurs with comparable substrate turnover efficiency, albeit at a slower initial triplet oxygen uptake for 5. The bioconjugate 5 is durable; it does not decompose under 1O2 photoreaction conditions. These results suggest a synthetic
使用功能化的不对称氟代-氟代烷基支架F 48 H 7 COOHPcZn(3)制备F 48 H 7 COOPcZn-6-氨基己酸-CTVALPGGYVRVC(5),这是一种可用于光动力疗法的Pep42肽生物共轭物,可以特异性地靶向GRP78伴侣蛋白过度表达,仅定位于某些癌细胞表面。还制备了类似的F 48 H 7 COOHPcCu(4),并阐明了其单晶X射线结构。尽管相对于F 64的非功能化单点配合物而言,位阻降低了PC的支架,在溶液中通过UV-vis光谱没有检测到聚集,对于任一3,4,或5,与缺乏π一致堆叠观察到结晶4。所述6-氨基己酸- Pep42部分减少的荧光效率5,相对于3,但对单重态氧(1 Ò 2)的产生,β的光化学氢过氧化- ( - ) -用香茅醇5和3具有相当的底物转换效率发生,尽管最初的三重态氧气吸收慢了5分钟。生物共轭物5耐用;它在1 O 2光反应条件下不会分解。这些结果表明

carbons by means of DFT. Finally, 19F ENDOR and easily observable paramagnetic NMR were found to relate well to the DFT computations, revealing negligible isotropic hyperfine (Fermi contact) contributions. The single-site isolation in solution and solid state and the relatively strong coordination of axial ligands, both attributed to the introduction of Rf groups, are features important for materials and
