摘要：

Some disubstituted diacetylene compounds (R-C C-C C-R', R=R' or R not equal R'), the symmetrical pTS and DNP, present a quasi unique property : a large size monomer single crystal can be converted into single crystals of conjugated polymer. Structural phase transitions occur in both pTS and DNP monomer crystals. The side groups are dipolar in the two cases : the structural changes lead respectively to antiferroelectric and ferroelectric low temperature phases. New results about DNP are presented.
