A new series of platinum(II) organometallic complexes with 3,8-bis-(3-hydroxy-3-methylbut-1-yn-1-yl)-1,10-phenanthroline (3,8-Phen-C(CH₃)₂OH) and nine respective arylethynyl ligands with different substituents (Pt(3,8-Phen-C(CH₃)₂OH)(Ph-R₂)₂: R₂ = H (1OH), 2-F (2OH), 3-F (3OH), 4-F (4OH), 4-Me (5OH), 4-CF₃ (6OH), 4-t-Bu (7OH), 3,5-di-CF₃ (8OH), 3,5-di-t-Bu (9OH)) were synthesized and their luminescences in solution and solid state were characterized by photoluminescence spectroscopy. The luminescence of each of the new complexes, 1OH – 9OH, in solution was assigned to the phosphorescence from the mixed transition of ³MLCT/³LLCT (LLCT = ligand-to-ligand charge transfer), revealing that two series had very similar emission spectra: Pt(3,8-PhenTMS)(-Ph-R)₂ 1TMS – 9TMS and Pt(3,8-PhenH)(Ph-R)₂ 1H – 9H in solution. In solid state, the emission spectra of three series of platinum organometallic complexes, 1OH – 9OH, 1H – 9H, and 1TMS – 9TMS, were observed over a wide range (500–1100 nm) because the phosphorescence of each of these complexes was assigned to the emission from the ³MLCT/³LLCT mixed transition and/or the transition of a metal−metal-to-ligand charge transfer, called ³MMLCT.

Results of vapochromism and vapoluminescence experiments with 13 species of volatile organic compounds (VOCs) for three series of the 27 above-mentioned platinum complexes suggested that the vapochromism of the present complex systems was induced by sterically hindered substituents of the arylethynyl ligands as tert-butyl substituents, and that the expansion of the space among the molecules in solid state is important for selective and multicolor detection with vapochromism and vapoluminescence for VOCs. Especially, the vapoluminescence experiment with VOCs for 9TMS, which was composed of a combination of the bulkiest ligands, 3,8-bis-(trimethylsilyl)ethynyl-1,10-phenanthroline and 3,5-di-t-butyl-phenylehtynyl ligands, among the present 27 complexes showed multicolor changes from yellow to dark brown, in contrast with respective VOCs.

与3,8-双-（3-羟基-3-甲基丁-1-yn-1-基）-1,10-菲咯啉（3,8-Phen -C（CH ）的铂（II）有机金属络合物的新系列₃）₂ OH）和9个各自的具有不同取代基的芳基乙炔基配体（Pt（3,8-Phen -C（CH ₃）₂ OH）（Ph-R ₂）₂：R ₂  = H（1OH），2-F（2OH），3-F（3OH），4-F（4OH），4-ME（5 OH），4-CF ₃（6 OH），4-吨-Bu（7 OH），3,5-二- CF ₃（8羟基），合成了3,5- di - t - Bu（9OH）），并通过光致发光光谱表征了它们在溶液和固态下的发光。每种新配合物在溶液中的发光1OH – 9OH均归因于³ MLCT / ³ LLCT的混合跃迁的磷光（LLCT =配体到配体的电荷转移），表明两个系列的发射非常相似光谱：Pt（3,8-Phen TMS）（- Ph-R）₂ 1TMS – 9TMS和Pt（3,8-Phen H）（Ph-R）₂ 1H – 9H在解决方案中。在固态下，在宽范围（500–1100 nm）内观察到了三个系列的铂有机金属配合物1OH – 9OH，1H – 9H和1TMS – 9TMS的发射光谱，因为这些配合物的磷光均已分配到³ MLCT / ³ LLCT混合过渡和/或金属-金属到配体电荷转移的过渡（称为³ MMLCT）的发射。

对上述27种铂络合物中的三个进行13种挥发性有机化合物（VOC）的气相色谱和气相发光实验的结果表明，本复合体系的气相色谱是由芳基乙炔基配体的空间位阻取代基（叔丁基）诱导的取代基，以及固态分子之间的空间扩展对于VOC的气相致变色和气相发光的选择性和多色检测非常重要。特别地，vapoluminescence实验的VOC为9TMS，其组成的体积最大的配体，3,8-双- （三甲基甲硅烷基）乙炔基-1,10-菲咯啉和3,5-二-的组合吨与相应的VOC相反，目前的27种配合物中的丁基-苯基-乙炔基配体显示出从黄色到深棕色的多色变化。
