Abstract:
A chromophore selected from the group consisting of whereDa and Db are independently selected from the group consisting of N, O, S, and P; Lg is a homolytic or heterolytic leaving group, wherein said leaving group comprises an atom selected from the group consisting of N, O, S, P, Cl, Br, and I attached to the fluorene ring carbon; m, n, o and p are independently selected from the range of integers greater than or equal to zero and less than or equal to ten; U, V, X, and Y are independently selected from the group consisting of CRkâ€²=CRlâ€², O, S, and Nâ€”Rmâ€², where Rkâ€², Rlâ€², and Rmâ€² are defined below; Ra, Rb, Rc and Rd are independently selected from the group consisting of (i) â€”H; (ii) a linear or branched alkyl group with up to 25 carbons; (iii) â€”(CH2CH2O)&agr;â€”(CH2)&bgr;ORa1; â€”(CH2CH2O)&agr;â€”(CH2)&bgr;NRa2Ra3; â€”(CH2CH2O)&agr;â€”(CH2)&bgr;CONRa2Ra3; â€”(CH2CH2O)&agr;â€”(CH2)&bgr;CN; â€”(CH2CH2O)&agr;â€”(CH2)&bgr;Cl; â€”(CH2CH2O)&agr;â€”(CH2)&bgr;Br; â€”(CH2CH2O)&agr;â€”(CH2)&bgr;I; â€”(CH2CH2O)&agr;â€”(CH2)&bgr;-Phenyl, where 0&lE;&agr;&lE;10 and 1&lE;&bgr;&lE;25 and Ra1, Ra2, and Ra3 are independently selected from the group consisting of H and a linear or branched alkyl group with up to 25 carbons; (iv) an aryl group; (v) a fused aromatic ring; and (vi) a polymerizable functionality; wherein one of Ra and Rb is not present when Da is O or S, and wherein one of Rc and Rd is not present when Db is O or S;Re, Rf, Rg, Rh, Ri, Rj, Rk, Rkâ€², Rl, Rlâ€², Rmâ€², Rp, Rq, Rr, Rs, Rt, Ru, Rv, R1, R2, and R3 are independently selected from the group consisting of (i) H; (ii) a linear or branched alkyl group with up to 25 carbons; (iii) â€”(CH2CH2O)&agr;â€”(CH2)&bgr;ORa1, â€”(CH2CH2O)&agr;â€”(CH2)&bgr;NRa2Ra3, â€”(CH2CH2O)&agr;â€”(CH2)&bgr;CONRa2Ra3, â€”(CH2CH2O)&agr;â€”(CH2)&bgr;CN, â€”(CH2CH2O)&agr;â€”(CH2)&bgr;Cl, â€”(CH2CH2O)&agr;â€”(CH2)&bgr;Br, â€”(CH2CH2O)&agr;â€”(CH2)&bgr;I, â€”(CH2CH2O)&agr;â€”(CH2)&bgr;-Phenyl, where 0&lE;&agr;&lE;10 and 1&lE;&bgr;&lE;25 and Ra1, Ra2, and Ra3 are independently selected from the group consisting of H and a linear or branched alkyl group with up to 25 carbons; (iv) an aryl group; (v) a fused aromatic ring; (vi) a polymerizable functionality; (vii) â€”F, â€”Br, â€”Cl, â€”I, phenyl; (viii) â€”NRe1Re2, â€”ORe3, and â€”SRe4, where Re1, Re2, Re3, Re4 are independently selected from the group consisting of (a) H; (b) a linear or branched alkyl group with up to 25 carbons; (c) phenyl; and (d) a polymerizable functionality or an electrically neutral salt thereof.
