Abstract

The preparation and characterization of new amphiphilic polysilanes containing chiral pendant ammonium groups are described. Polyalkylphenylsilanes (alkyl; C-1-C-8) (I) were prepared, and the Friedel-Crafts reaction of I wascarried out to give p-chloromethylated polysilanes (II). II were treated with optically active amines such as N, N-dimethyl-alpha-methylbenzylamine (1), N, N-dimethylphenylalaninol (2), N, N-dimethyl-O-acethylphenylalaninol (3), N, N-dimethyl-iso-leucinol (4), N, N-dimethylleucinol (5) and N, N-dimethyl-1-phenylethanol (6) to give the corresponding amphiphilic polysilanesbearing chiral pendant ammonium moieties. All polymers prepared were soluble in water, ethanol and acetonitrile. The circular dichromic spectra (CD) of the polymers in ethanol showed that the polymer had a screw-sense main chain.
