Popis:	By reaction of 2-(1-cyano-1-methylthio)methyleneindan-1,3-dione ( 2 ) with nucleophiles, the corresponding substituted compounds ( 10–16 ) as typical donor-acceptor chromogens were obtained. Novel methine dyes ( 24,25 ) absorbing in the near-IR region (650–850 nm) were synthesized by condensation of 16 and malononitrile with TiCl 4 and pyridine.
