1. A polymer comprising a repeat unit of formula 2 below: where n is an integer of 50 to 5,000;
p is an integer of 0 to 4; at least one of R1, R2, R3, and R4 is a radical selected from a group consisting of a compound represented by formula 1a, a compound represented by formula 1b, a compound represented by formula 1c, and a compound represented by formula 1d; and the remaining three of R1, R2, R3, and R4 are each independently one of hydrogen, halogen, a substituted or unsubstituted C1-C20 alkyl group, a substituted or unsubstituted C2-C20 alkenyl group, a substituted or unsubstituted C5-C12 cycloalkyl group, a substituted or unsubstituted C6-C40 aryl group, a substituted or unsubstituted C7-C15 aralkyl group, a substituted or unsubstituted C2-C20 alkynyl group, or a polar group selected from non-hydrocarbonaceous polar groups containing at least one of oxygen, nitrogen, phosphor, sulfur, silicon, and boron, wherein when none of R1, R2, R3, and R4 is hydrogen, halogen, or the non-hydrocarbonaceous polar group, R1 is connected to R2 or R3 is connected to R4 to form a C1-C10 alkylidene group, or R1 or R2 is connected to one of R3 and R4 to form a C4-C12 saturated or unsaturated cyclic group or a C6-C24 aromatic cyclic compound, the non-hydrocarbonaceous polar group is selected from a group consisting of —OR6, —OC(O)OR6, —R5OR6, —R5OC(O)OR6, —C(O)OR6, —R5C(O)OR6, —C(O)R6, —R5C(O)R6, —OC(O)R6, —R5OC(O)R6, —(R5O)p—OR6, —(OR5)pOR6, —C(O)—O—C(O)R6, —R5C(O)—O—C(O)R6, —SR6, —R5SR6, —SSR6, —R5SSR6, —S(═O)R6, —R5S(═O)R6, —R5C(═S)R6, —R5C(═S)SR6, —R5SO3R6, —SO3R6, —R5N═C═S, —NCO, R5—NCO, —CN, —R5CN, —NNC(═S)R6, —R5NNC(═S)R6, —NO2, —R5NO2, where R5 is selected from a group consisting of a substituted or unsubstituted C1-C20 alkyl group, a substituted or unsubstituted C2-C20 alkenyl group, a substituted or unsubstituted C5-C12 cycloalkyl group, a substituted or unsubstituted C6-C40 aryl group, a substituted or unsubstituted C7-C15 aralkyl group, and a substituted or unsubstituted C2-C20 alkynyl, and
R6, R7, and R8 are each independently one of hydrogen, halogen, a substituted or unsubstituted C1-C20 alkyl group, a substituted or unsubstituted C2-C20 alkenyl group, a substituted or unsubstituted C5-C12 cycloalkyl group, a substituted or unsubstituted C6-C40 aryl group, a substituted or unsubstituted C7-C15 aralkyl group, or a substituted or unsubstituted C2-C20 alkynyl, and where A is a substituted or unsubstituted C1-C20 alkylene group, carbonyl, carboxy, a substituted or unsubstituted C6-C40 arylene group; B is one of oxygen, sulfur and —NH—; X is one of oxygen and sulfur; R9 is a single bond or one compound selected from a group consisting of a substituted or unsubstituted C1-C20 alkylene group, a substituted or unsubstituted C2-C20 alkenylene group, a substituted or unsubstituted C5-C12 cycloalkylene group, a substituted or unsubstituted C6-C40 arylene group, a substituted or unsubstituted C7-C15 aralkylene group, or a substituted and unsubstituted C2-C20 alkylnylene group; and R10, R11, R12, R13, and R14 are each independently one of hydrogen, a substituted or unsubstituted C1-C20 alkyl group, a substituted or unsubstituted C1-C20 alkoxy group, a substituted or unsubstituted C6-C30 aryloxy group, and a substituted or unsubstituted C6-C40 aryl group, with the proviso that R10 in the formula 1a is not hydrogen; and R15 is hydrogen, a substituted or unsubstituted C1-C20 alkyl group, a substituted or unsubstituted C1-C20 alkoxy group, a substituted or unsubstituted C6-C30 aryloxy group, and a C6-C40 aryl group substituted with at least one halogen of Cl or F. |
