摘要：Functionalised crown ethers, process for their preparation and their applicationas complexing agents for ions, especially cations. The functionalised crown ethers

according to the invention correspond to the general formula (I): in which: n = 3, 4 or 5, m= 1, 2, 3 or 4 and the groups F, which are identical or different, are chosen from: in which:R1, R2 and R3 are chosen from H, aryl, cyano and halo and the groups R, -SOR and SO2Rwhere R denotes a C1-10 alkyl, C1-10 alkenyl or C1-10 alkynyl group, the said groupsbeing linear or branched and being optionally capable of being substituted by one ormore radicals chosen from hydroxyl, alkoxy, aryloxy, alkoxycarbonyl, carbonyl, halo, arylor nitrile radicals or an organometallic group of formula -M(X)3 in which M = Si or Sn andthe symbols X, which are identical or different, are chosen from C1-5 alkyl, C1-5 alkenyl,C1-5 alkynyl or aryl radicals; R', R'', R''' and R'''', which are identical or different, arechosen from H, C1-5 alkyl, C1-5 alkenyl, C1-5 alkynyl or aryl, it being additionally possiblefor the radicals R' and R'' on the one hand and R''' and R'''' on the other hand to form

together a carbonyl group; Y is chosen from Si, Sn, O, SO, SO2, -NA-, with A chosen fromH, C1-5 alkyl, C1-5 alkenyl, C1-5 alkynyl or aryl; Z denotes a direct bond, Si, Sn or else a -(C=O)- or -O-(C=O)- group, q = 0 or 1 0
