发明名称 DISTYRYLBENZENES
摘要 The distyrylbenzenes of the formula (1) in which X and X' independently of one another are -COO-or -CON(R4? in the o-position, a direct bond, oxygen, sulfur, -O-C1-3-alkylene-CON(R4)-, -SO2N(R4)-,-O-C1-3-alkylene-COO- or -OCO-, Y and Y' independently of one another are C1-20-alkylene, R1 and R? independently of one another are unsubstituted or substituted C1-8-alkyl or C3-4-alkylene, or R1 together with R2, or R? together with R?, is a heterocyclic ring, R2 and R? independently of one anothr are unsubstituted or substituted 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 picoline 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 apyridine 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 substituents, can be prepared by reacting a correspondingly substituted benzaldehyde with a p-xylylenephosphonate and then alkylating or protonising the distyrylbenzenediamine formed. The distyrylbenzenes are fluorescent brightening agents for organic materials. They are particularly suitable for use as additives to textile and laundry after-treatment agents which contain catonic textile softeners.
