1. A compound having a structure corresponding to formula (I):! ! where n is an integer from 0 to 2; ! s is an integer from 1 to 3; ! m is an integer from 0 to 12, provided that when n is 0, then m is not more than 8; and when n is 1, then m is not more than 10; ! Ar is a member selected from the group consisting of substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, and a fused ring system; ! each X represents a member independently selected from the group consisting of H, halogen, CN, CF3, OR5, SR5, acyl, C (O) OR5, C (O) NR6R7, S (O) 2R5, S (O) 2NR6R7, NR6R7, NR6S (O) 2R5, NR6C (O) R5, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl and substituted or unsubstituted heterocycloalkyl,! where each R5, R6 and R7 represents a member independently selected from the group consisting of H, acyl, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl,! where two of R5, R6 and R7, together with the atoms to which they are bonded, are optionally connected to form a 3-7 membered ring; ! each R1 and R2 is a member independently selected from the group consisting of H, halogen, CN, CF3, OR8, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, and substituted or unsubstituted heterocycloalkyl! where R8 is a member selected from the group consisting of H, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted aryl, substituted or not |
