Abstract:
A compound of formula whereinn is 1 or 2, m is 1 or 2, A is an anion; Y is a linear or branched alkylene radical of formula â€”[C(R5)2]râ€” wherein r is an integer of from 1 to 8 and the R5 radicals are each independently of the others hydrogen or C1-C4alkyl; â€”CX&boxH;CXâ€” wherein X is cyano, linear or branched C1-C8alkyl or di(linear or branched C1-C8alkyl)amino; â€”(CH2)qâ€”NR4â€”(CH2)qâ€” wherein R4 is hydrogen or C1-C4alkyl and q is 1, 2, 3 or 4; or a 1,2-cyclohexylene radical of formula: â€ƒor a 1,2-aryl radical of formula â€ƒwherein R9 is hydrogen, SO3H, CH2OH or CH2NH2, R and R1 are each independently of the other nitro, NR6R7 wherein R6 is linear or branched C1-C12alkyl and R7 is linear or branched C1-C12alkyl, with the proviso that R6 and R7 in the groups NR6R7 are not identical, or â€”CH2â€”NâŠ•R4R6R7 or â€”NâŠ•R4R6R7 wherein R4, R6 and R7 are as defined above, R2 and R3 are each independently of the other hydrogen, linear or branched C1-C4alkyl, unsubstituted aryl, or aryl substituted by cyano; by halogen; by OR5 or COOR5 wherein R5 is hydrogen or linear or branched C1-C4alkyl; by nitro; by linear or branched C1-C8alkyl; by NHR6 or NR6R7wherein R6 and R7 are identical or different and are each linear or branched C1-C12alkyl; by linear or branched C1-C8alkyl-R8 wherein R8 is a radical OR5, COOR5 or NR6R7 as defined above or is NH2; or by â€”NâŠ•R4R6R7 wherein R4, R6 and R7 are as defined above, and, when n and m are each 1, R2 and R3 are each hydrogen and Y is unsubstituted 1,2-cyclohexylene, R and R1 are not each nitro in the 5- and 5â€²-position, respectively, and, when n and m are each 1, R2 and R3 are each hydrogen and Y is unsubstituted 1,2-ethylene, R and R1 are not each NâŠ•(CH3)(C2H5)2 in the 4- and 4â€²-position, respectively.
