<p>Methods, based on the Wittig-Horner reaction, are provided for the synthesis of compounds of formula (I) wherein m is from 5-150, X and Y are independently selected from: CN, H, OH, COCH3, CO2H, CO2R1, where R1 is C1-12alkyl, NCS, SCN, CF3, CH2X where X is F, Cl, Br, OH, CHF2 and formula (IB), wherein J for each X and Y group is independently selected from: CH2, single covalent bond, OOC, CO2, O, CH2O, OCH2, CH2CO2, CH2OOC; p = 1-20; L for each X and Y group is independently selected from: O, CH2, OCO, CO2, S, NH; (a) is defined by formula (IC), wherein rings A, B and C are independently selected from phenyl, cyclohexyl, pyridine and pyrimidine and may be independently of each other substituted with at least one of Cl or F; linking groups A and B may be selected from single bond, CO2, OOC, CH2O, OCH2, CH2CH2, C C; Z is selected from CN, F, Cl, NO2, R, OR, CO2R, CF3, OOCR, NCS, SCN, where R = straight chain or branched chain alkyl and may include from 1-16 carbon atoms and including where one or more non-adjacent CH2 groups may be substituted by CH(CN), CH(CF3), CH(Cl), CH(CH3) in chiral or non-chiral form; provided that at least one of X and Y is selected from (IB); said method comprising the polymerisation of general formula (II), wherein X and Y are as defined for formula (I).</p> |
