Abstract

The synthesis of flavin-containing amphiphilic block copolymers using atom transfer radical polymerisation (ATRP) is described. In these systems, a flavin moiety is engineered into the ATRP initiator unit as an environmental probe and is subsequently used to produce three block copolymers featuring a hydrophobic methacrylate block and a DMAEM block. The dimethylamino unit of the latter is converted to a trimethylammonium unit to afford three amphiphilic block copolymers. Rheological measurements show that these materials form gels in dilute aqueous solution that can be disrupted upon irradiation with ultrasound. The disruption of the gel can be conveniently monitored by exploiting the solvatochromic nature of the S0–S2 absorption in the UV-vis spectrum in response to its changing environment.
