A. Sarkar et al., A NOVEL SERIES OF QUINOLINE CONTAINING ASYMMETRICALLY SUBSTITUTED POLYDIACETYLENES FOR 3RD-ORDER NONLINEAR-OPTICAL MATERIAL, Polymer bulletin, 41(4), 1998, pp. 425-431
A series of novel unsymmetrical diacetylenes have been prepared which
have quinolyl moiety as one of the directly linked sidegroups to the a
cetylenic backbone. One of the diacetylenes exists in two crystal form
s, one of which is solid state reactive. The polydiacetylenes obtained
from the monomers have generally long effective conjugation length as
indicated by their absorption spectra. The third-order nonlinear opti
cal susceptibility (chi((3))) of one of the polydiacetylenes has been
evaluated and found to be in the order of 10(-11) esu.
