Optical properties of poly(phenylacetylene) derivatives containing small-size amino-acid pendants groups

摘要

Three new phenylacetylene derivatives (1,2 and 3) containing amino-acid pendants were synthesized and polymerized by organorhodium complexes (Scheme 1). All the resulting polymers are chiral, showing high values of specific rotation (Table 1) and molar ellipticity in the #pi#->#pi#~* region ion chloroform (Figure 1).
