Abstract
The absorption, fluorescence excitation and dispersed emission spectra of a family of polydiacetylenes in solution are compared in order to elucidate the structure of several forms of polymer. An amplified sidegroup dependency showing an odd/even relationship in the number of methylene groups is discussed. A simple two-chromophore model is introduced to explain the heterogeneity found in these systems, including the variation of fluorescence quantum yield with excitation wavelength, resulting from the presence of more than one structural form of polymer in solution.
