Reversible thermochromism in hydrogen-bonded polymers containing polydiacetylenes

Out of the blue: A reversible temperature-dependent change in the absorption characteristics of spin-coated terephthalic acid/diacetylene polymers is observed. The polymer is prepared by topochemical photopolymerization of the diacetylene side chains of t
