联乙炔

The absorption spectra of the terpyridyl platinum acetylide complex containing monoazacrown moiety in the acetylide ligand was blue-shifted upon complexation with metal cations.

对位带有氮杂-15-冠-5冠醚的苯乙炔为辅助配体的三联吡啶Pt络合物TAC在金属离子的存在下吸收光谱的变化明显不同。

The energy of excited state depended on the nature of different cations. 3. 4-(4-tolyl)-6-phenyl-2, 2'-bipyridine platinum acetylide complex containing a monoazazcrown moiety in the acetylide ligand could signal Mg〓 specifically and displayed large changes both in color and in luminescence intensity upon complexation with Mg〓. The most striking result was that it could signal Mg〓 specifically even in the presence of alkali and alkaline earth metal ions in high concentrations.

对位带有氮杂-15-冠-5冠醚的苯乙炔为辅助配体的4-（4-甲基苯基）-6-苯基-2，2'-联吡啶Pt络合物AC，不仅在碱金属和碱土金属的存在下吸收光谱明显改变，更有意义的是，它只有在Mg〓离子存在时能够发光，因此可以通过发射光谱选择性的识别Mg〓，尤其可以在高浓度的其它金属离子存在下选择性的检出Mg〓离子。
