Newly synthesized ball-type Zn(II) and Mg(II) phthalocyanines containing four 1,1′-binaphthol substituents at peripheral and non-peripheral positions are presented. The structures of the synthesized compounds were characterized by using elemental analysis, UV-vis, FT-IR, 1H-NMR and mass spectroscopies. The ΦF values were 0.33, 0.08, 0.20 and 0.08 for 6–9, respectively. The ΦT values were 0.56, 0.85, 0.64 and 0.88 for 6–9, respectively. All the complexes showed reasonably large triplet lifetimes with τT values of 710 (6), 170 (7), 1490 (8) and 380 μs (9) in DMSO. These complexes offer potential as photosensitizers in photodynamic therapy.
新合成的球型Zn(II)和Mg(II)
酞菁在外围和非外围位置含有四个
1,1'-联萘酚取代基。通过元素分析、UV-vis、FT-IR、1H-NMR和质谱对合成化合物的结构进行了表征。 6-9 的 ΦF 值分别为 0.33、0.08、0.20 和 0.08。 6-9 的 ΦT 值分别为 0.56、0.85、0.64 和 0.88。所有配合物在
DMSO 中都显示出相当大的三线态寿命,τT 值为 710 (6)、170 (7)、1490 (8) 和 380 μs (9)。这些复合物在光动力疗法中具有作为光敏剂的潜力。
