Cu(I) complexes with aggregation-induced emission for enhanced photodynamic antibacterial application.

This communication reports the design of aggregation-induced emission (AIE)-featured PEG-condensed Cu(I)- p -MBA aggregates (PCuA). Benefiting from the AIE trait and intrinsic antibacterial property of Cu species, the as-developed PCuA exhibits enhanced photodynamic antibacterial activities against broad-spectrum bacteria, providing a paradigm in the design of novel antibacterial agents.
