“…4). 35 Metallic Pcs such as ZnPc and NiPc cages were synthesized via dynamic spiroborate exchange from diol-boronic acid condensation to form a spiroboronic ester bond using zinc or nickel phthalocyanine octaphenol (Zn or Ni Pc-8OH), [1,1 0 :4 0 ,1 0 0 0 -triphenyl]-2,2 0 0 0 3,3 0 0 0 -tetraphenol (Tp-4OH) and boronic acid as precursors. Moreover, cage products in yields of about 70% were obtained in DMF at 150 1C in 1 h and further purified by recrystallization.…”
