A photo‐ATRP protocol uses NIR radiation released by an LED at 790 nm to facilitate synthesis of block copolymers comprising UV‐absorbing moieties enabling the function of an optical filter there. Cyanines with heptamethine pattern and barbiturate group favor to activate copper(II) complexes to initiate the light‐induced synthesis of block copolymers with highly UV‐absorbing components. Comparative experiments with UV LEDs applying a UV‐based ATRP system show no initiation of living photopolymerization. Find out more in the Full Paper by B. Strehmel et al. on page 10444 ff.
