Abstract

In this study, the polar structure of a rigid /spl alpha/-helical polypeptide which is well known as a cholesteric liquid crystal polymer is investigated. The polypeptide has a large dipole moment along the helical axis by adding the dipole moment of peptide groups. On analogy of the copolyester, it is expected that the polypeptic form a cholesteric mesophase with polar structure.
