Organic dye molecules and nonlinear optical polymeric compounds containing chromophores

An organic dye molecular material having the following formula:

• where X1 is hydrocarbon, oxygen, sulfur, nitrogen, ester (CO2), or amide (CONR1), where R1 is an alky or phenyl group having 1 to 6 carbon atoms, D is an organic chromophore molecule, and n is an integer from 1 to 10;
• wherein the organic chromophore molecule D has a structure selected from the following formula (A-1), (A-2) and (A-3) in which each chromophore molecule is shown as D-OH:
• where R and R′ are each independently alkyl or phenyl groups having 1 to 10 carbon atoms, A1 is carbon or nitrogen, X2 is NO2, a sulfonyl-substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, CN, —C(CN)═C(CN)2, an ester group, a halogen element, or a haloalkyl group, and n is an integer from 1 to 11.
