Circle the wagons : Well‐defined cyclic poly(4‐vinylbenzylcarbazole) (cyclic PVBCZ) polymers with differing molecular weights were prepared efficiently by successive atom‐transfer radical polymerization (ATRP) and a click reaction (see picture; Σ=azide, Δ=alkynyl groups). The cyclic PVBCZ displayed a higher glass transition temperature than its linear precursor and has a higher fluorescence emission.
