通过使用新合成的含二亚胺和十二烷基二膦配体的铜（I）配合物，实现了基于固态蓝色和橙子光致发光的可逆氧传感能力。我们发现固态的[Cu（dmp）（dfppe）] PF 6（dmp = 2，9-二甲基-1，10-菲咯啉，dfppe = 1，2-双[双（五氟苯基）膦基]乙烷）在氩气下有很强的蓝光发射，而在空气中几乎看不见。单晶X-射线结构分析表明，配合物具有显着的柱状空隙空间。[Cu（dmp）（dfppe）] PF 6在氩气氛下的固态中显示出极长的发光寿命（τ1 = 160 μs（88%），τ2 = 22 μs（12%）），这是所有含二亚胺配体的铜（I）配合物的最大值之一，并且在空气中急剧降低（τ1 = 2.4 μs（85%），τ2 = 0.5 μs（15%））。dfppe配体的引入显著增加了配体中心跃迁的贡献，导致长寿命的激发态。本文还研究了[Cu（4,7 dmp）（dfppe）] PF_6（4,7 dmp = 4，7-二甲基-1，10-菲咯啉）的橙子氧响应发射，并对五种新的铜（I）配合物的电子物理性质进行了研究。
Reversible oxygen sensing abilities based on blue and orange photoluminescence in the solid state are achieved by using newly synthesized copper(I) complexes bearing diimine and dodecafluorinated diphosphine ligands. We found that the blue emission of [Cu(dmp)(dfppe)]PF6 (dmp = 2,9-dimethyl-1,10-phenanthroline, dfppe = 1,2-bis[bis(pentafluorophenyl)phosphino]ethane) in the solid state is very strong under argon, while it is nearly invisible under air. Single crystal X-ray structural analysis reveals that the complex has significant columnar void spaces. [Cu(dmp)(dfppe)]PF6 shows an extremely long lifetime of the emission in the solid state under an argon atmosphere (τ1 = 160 μs (88%), τ2 = 22 μs (12%)), which is one of the largest values for all copper(I) complexes bearing diimine ligands, and it is drastically decreased under air (τ1 = 2.4 μs (85%), τ2 = 0.5 μs (15%)). The employment of the dfppe ligand markedly increases the contribution of ligand centred transition, leading to the long-lived excited state. The orange oxygen responsive emission of [Cu(47dmp)(dfppe)]PF6 (47dmp = 4,7-dimethyl-1,10-phenanthroline) is also examined with the help of an investigation of the photophysics of five new compounds of the copper(I) complexes.
