实验发现： 1.4-N，N-二甲基苯乙炔为辅助配体的三联吡啶Pt络合物TA在质子存在下吸收和发光变化明显，因此可以通过颜色或发光的变化检测微量质子的存在。

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。

All these observation furthers demonstrated the excited state properties of platinum polypyridyl acetylide complexes could be tuned by ancillary acetylide ligand. Proton or metal cation could be used as switch to change the order of the lowest excited state from LLCT to MLCT.

以上工作从另一角度再次证明，利用辅助配体的电子效应，能明显改善三联吡啶Pt络合物的激发态性质，其中质子或金属离子有效调节HOMO轨道的能量，实现了LLCT激发态向MLCT激发态的转换。

Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.

在两个相邻位置的苯基对位位置上接有一甲氧基的衍生物3a"和4a"也可利用类似的质子化反应合成，唯有错合物3a'= CpRu(PPh32， Ar2 = fluorenyl 可以稳定於溶液中，不会进行上述反应，如将其溶於四氢呋喃溶液加热至沸腾则会分解产生无法鉴定的化合物。
