Abstract
The present invention provides, as heteroaromatic compounds made functional so as to be used for nonlinear optical materials, compounds represented by the following general formula (1), and also provides polymers obtained from these and nonlinear optical parts comprising such polymers. In the formula, Ar.sup.1 and Ar.sup.2 each represents a divalent aromatic group; R.sup.1, R.sup.2 and R.sup.3 each represents an atom or a group independently selected from a hydrogen atom or an alkyl group and an aromatic group; X.sup.1 represents a monovalent organic group; n represents an integer of 2 to 12; and Z.sup.1 and Z.sup.2 each represents a group independently selected from electron attractive functional groups. ##STR1##
