摘要：

A study is carried out to demonstrate that a stereoregular, cis-transoidal poly(4-carboxyphenyl)acatylene (poly-1-H) can be prepared directly by the homogeneous, stereospecific polymerization of (4-carboxyphenyl)acetylene (1-H) in water in the absence of surfactants and any organic solvents, using water-soluble rhodium complexes in the presence of bases. Furthermore, it is shown that the macromolecular helicity can be induced on the polymer in water as a result of noncovalent, electrostatic interactions with natural, free amino acids.
