Abstract
Two optically active poly(menthoxycarbonylphenyleneethynylene)s were synthe sized by polycondensation using a palladium-copper catalyst system. All pol ymers showed Cotton effects in the absorption region of the main chain, imp lying that chirality is induced to the main chain. Moreover, these chiral p olymers showed the enantioselective recognition ability for chiral menthol in the circular dichroism (CD) spectra. (C) 2000 Elsevier Science Ltd. All rights reserved.
