New polydiacetylenes (PDAs) have been synthesized either by UV or ?-irradiation of diacetylenes or by 'polymer analogous' reactions of suitable precursors. PDAs with platinum moieties coordinated to the backbone have been synthesized and characterized by reference to novel, metallated oligomeric enynes. Metal-containing groups (e.g. Ru, Mo, Ni, Cu) have also been attached to PDAs through suitably functionalized side-chains, e.g. phosphinyl, (dialkyl)amino and bipyridyl groups. New diacetylenes incorporating the bases of DNA (adenine, thymine, cytosine) have been synthesized but in general do not polymerize by ?-irradiation. Nevertheless, thymine- and cytosine-containing PDAs have been characterized. The nonlinear optical properties of selected functionalized PDAs have been studied by the z-scan technique.
