Polydiacetylene (2) of varying molecular weight has been formed by UV- or 60Co ?-irradiation of the diacetylene PhCH2CO2(CH2)9-CqqCqqCqqC(CH2)9O2CCH2 Ph (3), with conversions of 30->95%. Samples of (2) with differing physical properties have been studied, in the bulk phase, by CPMAS 13C NMR and VIS/UV spectroscopy and by DSC; complementary spectroscopic data on solutions of (2), including fluorescence studies, are also reported. Spectroscopic studies support the presence of an extended planar conjugated backbone in `as polymerized' blue-black samples of (2), from which various forms of red-coloured polymer, with shorter conjugation lengths, can be obtained. Studies of the thermal behaviour indicate the existence of several differing thermal transitions for these materials and the results are discussed.
