Vorschrift

A mixture of 0.80 g (1 mmol) of 1-butyl-2-(2-{3-[2-(1-butyl-1H-benzo[cd]indol-2-ylidene)ethylidene]-2-(N,N-diphenylamino)cyclopent-1-en-1-yl)ethenyl)-benzo[cd]indol-1-ium perchlorate, 3.1 g (1.5 mmol) of sodium 1,1,3,3,3-pentafluoro-2-(pivaloyloxy)propanesulfonate aqueous solution, 16 g of water, and 16 g of methyl isobutyl ketone was stirred overnight at room temperature, whereupon the organic layer was taken out. The organic layer was washed with water and concentrated in vacuum. Diisopropyl ether was added to the residue for recrystallization. The crystal was collected and dried in vacuum, obtaining the target compound, 1-butyl-2-(2-{3-[2-(1-butyl-1H-benzo[cd]indol-2-ylidene)ethylidene]-2-(N,N-diphenylamino)cyclopent-1-en-1-yl)ethenyl)-benzo[cd]-indol-1-ium 1,1,3,3,3-pentafluoro-2-(pivaloyloxy)propane-sulfonate. Brown crystal, 0.88 g, yield 86%.
