1. A method of synthesizing an electro-optical material comprising a polymer having a poly(imido sulfide) backbone and an electro-optical chromophore having general Formula I:the method comprising
reacting a sulfide with a N-(halogenated biphenyl) bismaleimide and with the optical chromophore in a solvent utilizing a catalyst; maintaining the reaction temperature between about 20° C. and about 60° C. for about two hours; precipitating the resulting polymer into a solution of methanol and hydrochloric acid; washing the resulting precipitated polymer with methanol; drying the polymer in a vacuum oven thereby obtaining an EO material;wherein, in the compound of Formula I;
C* denotes a chiral carbon atom; D is an electron donating group; B comprises at least one bivalent ring; R2 and R3 are different from one another; and R2 is selected from the group consisting of H, substituted or unsubstituted C1-C10 alkyl, substituted or unsubstituted C2-C10 alkenyl, substituted or unsubstituted C2-C10 alkynyl, substituted or unsubstituted aryl, substituted or unsubstituted alkylaryl, substituted or unsubstituted carbocycle, substituted or unsubstituted heterocycle, substituted or unsubstituted cyclohexyl, and (CH2)n—O—CH2)n where n is an integer from 1 through 10; and R3 is selected from the group consisting of substituted or unsubstituted aryl, substituted or unsubstituted alkylaryl, substituted or unsubstituted carbocycle, substituted or unsubstituted heterocycle, substituted or unsubstituted cyclohexyl, and (CH2)n—O—(CH2)n where n is an integer from 1 through 10; or R2 and R3 together form a ring structure or a substituted ring structure; and the compound of Formula I has, at any location, at least one terminal —SH group capable of reacting with a maleimide bond. |
