摘要：

The synthesis of two new asymmetrical diacetylene (DA) derivatives is described: 1-(4-fluorobenzenesulfonyloxy)-6-(4-trifluoromethylbenzenesulfonyloxy)-2,4-hexadiyne (FBS/TFMBS) and 1-(2,4-dinitrophenoxy)-6-(4-methyl-2-nitrophenoxy)-2,4-hexadiyne (DNP/MNP). Results are presented on crystal growth, crystal structure analysis and dielectric properties. Both DAs polymerize thermally in the solid state and have polar ("ferroelectric") individual chains. The different chains in the unit cell are arranged centrosymmetrically in FBS/TFMBS, but non-centrosymmetrically in DNP/MNP.
