A novel polystyrene with non-symmetrical zinc phthalocyanines as terminal group

Azides and Porphyrinoids: Synthetic Approaches and Applications. Part 2—Azides, Phthalocyanines, Subphthalocyanines and Porphyrazines

“…The photophysical properties of the phthalocyanine SiPc39 were not affected after the mentioned conjugation taking place, as evidenced by UV-Vis absorption and emission spectroscopy. In 2017, Gül and co-workers selected the zinc phthalocyanine ZnPc40 with three tertbutylphenoxy groups and one 4-ethynylbenzyloxy moiety to be coupled to azido polystyrene PS-N3 under CuAAC conditions (CuBr/PMDETA) (Scheme 21) [43]. The A3B-type Pc ZnPc40 was obtained through the condensation of 4-(4-ethynylbenzyloxy)phthalonitrile and 4-(4-tertbutylphenoxy)phthalonitrile in 2-dimethylaminoethanol (DMAE) and the polymer was obtained from the azidation of the bromo-terminated polystyrene (PS-Br).…”

Biological properties of novel mono and double-decker hexadeca-substituted metal phthalocyanines

“…17,18 Improved solubility is usually achieved by the addition of long alkyl chains or bulky substituents on the α- and/or β-positions of the Pc ring and insertion of metal ions into the Pc cavity. 19–31 Also, the introduction of fluorinated-substituents in the phthalocyanine structure leads to high solubility of the phthalocyanines and increases their thermal and chemical stability. 32–34…”

Synthesis of tetrakis bromine terminated phthalocyanine and its methylmethacrylate polymers via ATRP

“…31 Recently, our group reported the synthesis of a new functional polystyrene polymer with a zinc Pc terminal that involved a click reaction between nonsymmetrical terminal-alkynyl-containing zinc Pc and azide-end functional polystyrene. 32 Poor solubility and slippery π − π stacks restricted the applications of Pcs. Overcoming these limitations required several attempts.…”
