Abstract

Communication: Unsaturated ladder polymers consisting of a perfect sequence of all-carbon six-membered rings (polycatafusenes) are predicted to exhibit intrinsic electrical conductivity and high optical nonlinearity. One step towards this goal, the chemically induced unfolding of a coiled ladder polymer (see Figure), where the geometries of the carbons marked “B” regulates the overall structure, is reported.
