Abstract in another language

The synthesis, solubility, and thermal behavior of soluble, fusible, liquid-crystalline derivatives of poly(1,4-phenylenevinylene) (1) is described. The improved solubility and fusibility were accomplished by reducing interchain interactions without change of the rigid rod-like character. The interchain interactions were lowered by decreasing the structural regularity of the repeating units. The synthesis of derivatives of 1 was accomplished by the palladium-catalyzed coupling of dihalogenoarenes and ethylene to avoid cis-vinylene units. Irreversible crosslinking was observed from fusible products on annealing above the softening point.
