Abstract:This study reports the synthesis of three silicon phthalocyanines (SiPc1–3) bearing 2‐dimethylaminoethoxy, 2‐[2‐(dimethylamino)ethoxy]ethoxy, or 2‐{2‐[2‐(dimethylamino)ethoxy]ethoxy}ethoxy on axial positions. Also, their quaternized derivatives (SiPcQ1–3) were prepared. The effect of ligand length on the biological features of water‐soluble silicon phthalocyanines (SiPcQ1–3) was investigated. The highest antimicrobial activity was obtained 32 μg/mL for SiPcQ1 against double‐distilled water, E. hirae, and E. fa… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
