Highly coplanar polythiophenes with-C≡CR side chains: Self-assembly, linear and nonlinear optical properties, and piezochromism

Self-assembly of polythiophenes with C≡ CR (R = alkyl, phenyl, etc.) side chains has been investigated. Seven new polymers consisting of head-to-head and tail-to-tail 2,2-bithiophenes with C≡ CR side chains were synthesized. The new polymers include alter

Palladium-catalyzed syntheses of polyethynyl-substituted 2,2′-bithiophenes

The syntheses of polyethynyl-substituted 2,2′-bithiophenes 2 and related 5,5′-dicarbaldehyde derivatives 1 are described. The treatment of easily available polybrominated 2,2′-bithiophenes 3 and 2,2′-bithiophene-5,5′-dicarbaldehydes 4 with phenyl or (trimethylsilyl)acetylene in the presence of PdII and CuI in (i-Pr)2NH yields substituted polyethynyl-2,2′-bithiophene compounds. The Me3Si protecting groups can be removed by protodesilylation under basic conditions to give the corresponding terminal ethynyl groups. These polyethynyl-bithiophenes could be interesting precursors for the synthesis of macrocycles with interesting properties.
