Abstract

An organic nonlinear optical substance having the formula (I): ##STR1## wherein R.sup.1 represents --H or --CH.sub.3 ; PA1 n is 0, 1, or 2; PA1 A represents Z.sup.1 --Ar, ##STR2## wherein Ar represents a 6-14 membered aromatic group including a heterocyclic ring or bisphenylene type ring; Z.sup.1 represents H--, R.sup.5 R.sup.6 N--, R.sup.7 O--, R.sup.8 S--, NC--, R.sup.9 OCO--, R.sup.10 COO--, O.sub.2 N--, R.sup.11 R.sup.12 NOC, R.sup.13 CO(R.sup.14)N--, or R.sup.15 --; Z.sup.2, Z.sup.3, and Z.sup.4 independently represent H--, a C.sub.1 -C.sub.8 alkyl--, R.sup.16 O--, R.sup.17 R.sup.18 N, R.sup.19 S--, O.sub.2 N--, or two R.sup.16 being, in combination, R.sup.20 CH<; R.sup.2 represents H-- or a C.sub.1 -C.sub.12 alkyl; R.sup.5 to R.sup.20 independently represent H--, or a C.sub.1 -C.sub.10 hydrocarbon residue; Z.sup.5 independently represents H--, a C.sub.1 -C.sub.8 saturated hydrocarbon residue, O.sub.2 N--, R.sup.21 O--, R.sup.22 S--, NC--, or R.sup.23 R.sup.24 N-- wherein R.sup.21 to R.sup.24 independently represent H or a C.sub.1 -C.sub.8 saturated hydrocarbon residue; X represents --S--, --O--, or >NR.sup.28 ; r is 0 or an integer of 1 to 3; and R.sup.28 represents H or a hy…
