Abstract
Distyryl compounds of the formula ##STR1## wherein A denotes 1,4-phenylene, 4,4'"'"'-biphenylylene, 4,4"-terphenylylene, 1,4-, 1,5- or 2,6-naphthylene, 9,10-dihydro-2,7-phenanthrenylene or 2,7-dibenzofuranylene,
R1 denotes an optionally functionally modified phosphonic acid, phosphonyl or phosphinyl group,
R2 denotes hydrogen, an optionally functionally modified phosphonic acid, phosphonyl or phosphinyl group, sulpho, carboxyl, alkoxycarbonyl, aryloxycarbonyl, aralkoxycarbonyl, aminocarbonyl, cyano, halogen, alkyl, aralkyl, alkenyl, hydroxyl, alkoxy, aralkoxy, cycloalkoxy, aryloxy or alkylmercapto and
R3 and R4 denote hydrogen, halogen, alkyl, alkenyl, aryl, aralkyl, alkoxy, alkoxycarbonyl, aminocarbonyl, cyano, sulpho, aminosulphonyl, acyl, acylamino, hydroxyl, aryloxy, aralkoxy, alkenyloxy, carboxyl or acyloxy
and wherein
the cyclic and acyclic radicals can contain non-chromophoric substituents, processes for the preparation of these compounds and their use for whitening synthetic, semi-synthetic and natural organic, high-molecular materials and for the production of laser radiation.
