Synthesis and [2+2]-photodimerisation of monothiomaleimide functionalised linear and brush-like polymers

[2+2]-Photodimerisation of monothiomaleimides has been demonstrated on functionalised linear and brush-like polymers. In water/acetonitrile (95 : 5) mixtures the rate of reaction is accelerated significantly by irradiation of the thiomaleimide end group ( λ max = 350 nm) with UV light, reaching full...

Description
Summary:[2+2]-Photodimerisation of monothiomaleimides has been demonstrated on functionalised linear and brush-like polymers. In water/acetonitrile (95 : 5) mixtures the rate of reaction is accelerated significantly by irradiation of the thiomaleimide end group ( λ max = 350 nm) with UV light, reaching full conversion within 10 minutes. The first example of [2+2]-photocycloaddition of monothiomaleimide-functionalised linear and brush-like polymers is demonstrated, with reactions complete within 10 min upon irradiation with UV light (200 W, 320-390 nm).
