TLDR
In this paper, the authors measured the dielectric permittivities of p TS diacetylene in the directions parallel and perpendicular to the direction of polymer chain growth and identified the transition as an antiferroelectric one, the sublattice polarization being most probably the order parameter.About:

Reinvestigation of generation and transport of charge carriers in crystalline polydiacetylenes (PDAs)
T. Blum,Heinz Bässler +1 more
TL;DR: In this paper, the authors re-examined data on stationary and pulsed photoconduction in PDA-TS and re-enforce the occurrence of geminate pair recombination, yet show that the conventional onedimensional version of Onsager's theory is inappropriate because it ignores ballistic electron-hole pair separation and geminate 1D-recombination of a pair of Coulombically unbound charges on the same chain.

Anisotropy of the charge-carrier mobility in polydiacetylene crystals
TL;DR: In this paper, the anisotropic mobility of excess charge carriers in pure and mixed polydiacetylene derivatives was determined by time-resolved measurement of the microwave conductivity.

Dynamic Stark effect as a probe of the evolution of geminate electron-hole pairs in a conjugated polymer
TL;DR: In this paper, a transient Stark shift of the absorption band was observed and related to kinetics of generated excitons and electron-hole pairs, which provided unique information on the charge redistribution in excited states.

Optical Nonlinearities in One-Dimensional-Conjugated Polymer Crystals.
TL;DR: The one-dimensional electronic delocalization that results from the solid-state polymerization of diacetylenes produces a dramatic enhancement of the optical nonlinearities of these compounds as discussed by the authors.

Investigation of the topochemical solid‐state polymerization of a diacetylene by X‐ray methods and brillouin‐spectroscopy
TL;DR: In this paper, the crystal structure of a polymerizable diacetylene monomer has been solved and the coordinates of all atoms prior and after the reaction have been determined, and the length of the growing polymer chains and their distribution in the monomer matrix can be determined by the evaluation of the Brillouin spectra in terms of a model which considers the polymerizing crystal as a composite material of high modulus rod-like macromolecules dispersed in the low-modulus matrix of the residual monomer.
