Abstract:
The invention relates to difluoroboradiazaindacene dyes of the formula (1) where R1=fluoro-substituted phenyl residue C6HmFn where n=1 to 5 and m+n=5; or fluoro-substituted naphthyl residue C10HmFn where n=1 to 9 and m+n=9; R2=CH3, C2H5, C3H7, or C4H9; R3=alkyl, aryl, or vinyl aryl; R4, R5=H, F, or an R4 and R5 bridging residue CH═CH—CH═CH; R6, R7=H, F, or an R6 and R7 bridging residue CH═CH—CH═CH; and R8=alkyl or aryl.
