Asymmetrically tetra-substituted phthalocyanine derivatives: synthesis, photophysical and photochemical properties

Sonophotochemical and photochemical efficiency of thiazole-containing metal phthalocyanines and their gold nanoconjugates

“…Dilber et al investigated the photophysical and photochemical features of new asymmetrically substituted metal-free and zinc phthalocyanine derivatives bearing 4-(4-(5-phenyl-1,3,4-oxadiazol-2-yl)phenoxy) and 4-(2-(benzo[d]thiazol-2-yl)phenoxy) groups. The singlet oxygen quantum yields obtained were 0.17 and 0.69 [ 73 ]. Nene and Nyokong prepared water soluble zinc phthalocyanine-bearing thiazole groups.…”

Water-soluble phthalocyanine photosensitizers for photodynamic therapy

“…They are used in many applications such as semiconductors [ 12 ], dye-based solar cells [ 13 ], electrochromic systems [ 14 ], molecular electronics [ 15 ], liquid crystals [ 16 ], data storage materials [ 17 ], laser dyes [ 18 ], chemical sensors [ 19 ], catalysts [ 20 ], and PDT for cancer treatment [ 21 ] due to their excellent electrochemical, thermal, and optical properties. Since phthalocyanines have a very similar structure to that of porphyrins and have suitable properties for ideal photosensitizers, they are known as a class of second-generation photosensitizers [ 22 , 23 ]. Moreover, these compounds are used as photosensitizers in PDT because they show strong light absorption between 600 and 800 nm in the electronic spectrum, do not show toxicity in the absence of light, and destroy tumor tissues by producing high singlet oxygen or radicals [ 24 ].…”
