Y. Nishihara et al., Homo-coupling polycondensation of bis(alkynylsilane)s mediated by copper(I) chloride: A new synthesis of poly(arylenebutadiynylene)s, CHEM LETT, (10), 2001, pp. 950-951
Homo-coupling polycondensation of aromatic compounds bearing two (trimethyl
silyl)ethynyl groups mediated by copper(I) chloride in DMF gives conjugated
poly(arylenebutadiynylene)s in up to 94% yield with molecular weight of 40
00-8900 (M-w/M-n = 1.78-2.09).
