Description Topochemical reactivity of some conjugated diacetylenes with pi-conjugating substituents upon exposure to gamma-radiation, UV-visible radiation and upon thermal annealing is described. Few of the diacetylenes undergo solid state polymerization to provide corresponding polydiacetylenes. The reflectance spectra of the resultant polydiacetylenes showed significant backbone-side-group electron coupling. The third-order nonlinear susceptibility of two of the polydiacetylenes obtained were evaluated using Maker's fringe technique. The third-order nonlinear susceptibility, chi((3)) value obtained for the two samples were in the order of 10(-11) esu for the fully polymerized polydiacetylene films. These values are comparable to the values reported previously for PDAs with aromatic sidegroups.
