Poly(oxanorbornene)s bearing triphenylphosphonium and PEGylated zinc(ii) phthalocyanine with boosted photobiological activity and singlet oxygen generation

Poly(oxanorbornene)s bearing TPP and PEGylated ZnPc with varying compositions have been synthesized. Thus, highest reported singlet oxygen generation for a Pc derivative in water ( Φ Δ = 0.93) and excellent biological activity have been accomplished.
