Copoly(4-dodecyloxyl-3,5-dihydroxymethyl-phenylacetylene/p-pinanyldimethylsilylphenylacetylene) (copoly (1/2)) consist of both the cis-cisoidal sequence of achiral 4-dodecyloxyl-3,5-dihydroxymethyl-phenylacetylene (1) and cis-transoidal sequence of chiral p-pinanyldimethylsilylphenylacetylene (2). The reactivity ratios of 1 and 2 in the copolymerization were estimated as r(1) = 1.49 and r(2) = 0.50, respectively. By replacing THE (a good solvent) of copoly(1/2) solution with methanol (a poor solvent) gradually by concentration-driven permeation through a membrane for several times, stepwise increase in the CD intensity at 308 nm arisen from the cis-cisoidal main-chain was observed. The local chirality in chiral 2 units was successfully transmitted to the cis-cisoidal sequence of achiral 1. Even when the molar ratio of 1/2 reaches 50, this method of the multiple-stage-solventexchange is still effective for transmitting the local chirality in 2 to the cis-cisoidal sequence 1 in the copolymer. Directly adding methanol to the copoly(1/2)'s solution and annealing of copoly(1/2) in THE/methanol could not realize this chiral teletransmission. Hence, this new method of the multiple stage solvent exchange in the copolymer solution through a membrane is suitable and efficient to realize the efficient chirality transmission and amplification in the cis-cisoidal polyacetylene.
