Abstract The distyrylbiphenyls of the formula Image in which X and X' independently of one another are a direct bond, oxygen, sulfur, -O-C1-3-alkylene-CON(R4)- -CON(R4)-, -O-C1-3-alkylene-COO-, OCO or -COO-, with the proviso that if n + n? = X and X' may not be -CON(R4)- or O-C1-3-alkylene-CON(R4)-, and if n + n1 = 2 and X and X' are -CON(R4)- or -COO-, A? may not be a phosphite or phosphonate anion, and Y and Y' independ- ently of one another are C1-20-alkylene, R1 and R? indep- endently of one another are unsubstituted or substituted C1-8-alkyl or C3-4-alkenyl, or R1 together with R2, or R? together with R?, is a heterocyclic ring, R2 and R? independently of one another are unsubstituted or substi- tuted C1-8-alkyl or C3-4-alkenyl, or R2 together with R1, or R? together with R?, is a heterocyclic ring, or R1 and R2, or R? and R?, together with R3 are a pyridine or pico- line ring, R3 is hydrogen, unsubstituted or substituted C1-4-alkyl or C3-4-alkenyl or together with R1 and R2, or with R? and R?, is a pyridine or picoline ring, R4 is hydrogen or unsubstituted or substituted C1-6-alkyl, A? is a colourless anion and n and n' independently of one another are the number 0 or 1, and the benzene nuclei B and C can also be substituted by non-chromophoric sub- stituents, can be prepared by reacting a correspondingly substituted benzaldehyde with a biphenyl phosphonate and then alkylating or protonating the distyrylbiphenyldi- amine formed. The distyrylbiphenyls are fluorescent brightening agents for organic materials. They are particularly suitable for use as additives for textile and laundry after-treatment agents which contain cationic textile softeners.
