Synthesis and properties of optically active nanostructured polymers bearing amino acid moieties by direct polycondensation of 4,4΄-thiobis(2-tert-butyl-5-methylphenol) with chiral diacids.
Abstract
Four derivatives of N-trimellitylimido-l-amino acid (4a–4d) were prepared by the reaction of trimellitic anhydride (1) with the
