ABSTRACT:
The present invention provides a second-order nonlinear optical polymer including a polymer backbone and side groups bonded to the polymer backbone, wherein the side groups include one or more of a first nonlinear optical group represented by the following formula (C-1) and one or more of a second nonlinear optical group represented by the following formula (C-2) or (C-2)': ##STR1## wherein .pi..sub.1 to .pi..sub.n, .pi.'.sub.1, .pi.'.sub.2, and .pi.".sub.1 each represent independently a .pi.-conjugated cyclic compound group; X.sub.1 to X.sub.n-1, X'.sub.1, Y.sub.1 to Y.sub.n-1, and Y'.sub.1 each represent independently CH, N, or N.fwdarw.O; A.sub.1, A.sub.2, and A.sub.3 each represent independently an electron attracting group; D.sub.1, D.sub.2, and D.sub.3 each represent independently an electron donating group; and n represents an integer of 3 or greater.
