DOI: 10.1016/j.dyepig.2021.109270
Abstract: Abstract Zinc(II) phthalocyanines are favorable candidates as photosensitizers (PSs) for photodynamic therapy (PDT). However, zinc(II) phthalocyanines also suffer from poor water solubility and low tumor-targeting ability. In this study, a novel zinc(II) phthalocyanine tetra-substituted with… read more here.
