Abstract:

The synthesis, thermal and spectroscopic properties of 28 rare-earth containing stilbazolium dyes are described. The complexes are prepared by reaction of the corresponding stilbazolium bromide (hemicyanine bromide) with a lanthanide salt and with a pyrazolone or a beta-diketone. The bromide is replaced by a tetrakis pyrazolonato or by a tetrakis beta-diketonato lanthanide(III) counter ion.
