Abstract
The second harmonic coefficient d(33) values of a series of polyester nonli near optical (NLO) polymers, differing in their electron withdrawing substi tuent, were experimentally measured. The observed order of contribution of the substituents towards d(33) value was rationalized by a frequency factor dependence. Excellent photostability and the highest d(33) value among the series have been found for the polyester with 2,4-dinitro substituents in the side chain. A possible influence of intermolecular interaction is also indicated. (C) 1999 Kluwer Academic Publishers.
