本文报道了28个含稀土的芪类染料的合成、热性质和光谱性质。配合物通过相应的溴化芪唑（溴化半花菁）与镧系元素盐和与吡唑啉酮或β-二酮反应来制备。溴化物被四吡唑啉酮或四β-二酮镧系元素（III）抗衡离子替代。(C)2000 Elsevier Science S.A. All rights reserved.
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 P-diketone. The bromide is replaced by a tetrakis pyrazolonato or by a tetrakis beta-diketonato lanthanide(III) counter ion. (C) 2000 Elsevier Science S.A. All rights reserved.
