This article presents the molecular orientation and second-order optical nonlinearity of newly prepared polyureas and copolyurea with dipole moments aligned transverse to the main backbone. Nonlinear optical (NLO) polyureas, TPU and TPU2, were prepared from 2,4-diamino-4Π-nitroazobenzene (2R-DIAMINE
