摘要：

A study was conducted to demonstrate the steric stabilization effects in nickel-catalyzed regioregular poly(3-hexylthiophene) (P3HT) synthesis. The - and 5-substituted halogen moieties were reversed in the synthesis of the new thiophene monomer the it was used ton initiate investigations to demonstrate the regioregular P3HT by the Ni(dppp)Cl2 catalyst. The reversed thiophene monomer was synthesized by initiation with 1.1 equivalent of n-butyllithium and N,N,N,N'-tetramethyl-1,2-ethylenediamine (TMEDA) in diethyl ether. Iodination was accomplished through a standard iodination procedure with iodine and iodobenzene diacetate in dichloromethane. Iodination was performed after distillation of the 2-bromo-3-hexylthiophene isomer and 2,5-dibromothiophene side-product for the desired product.
