  Improving oxygen sensing performance via inner-molecular π-π stacking in a series of phosphorescent Cu(I) complexes

  摘要：

  In this paper, six phosphorescent Cu(I) complexes with three diamine ligands and two phosphorous ligands were prepared. Detailed discussion was performed on these complexes, including single crystals, quantum mechanics theoretical calculation, absorption spectra, emission spectra, emission quantum yields and excited state decay dynamics. Large conjugation planes and π-π stacking were found in these complexes. Their emission was originated from MLCT excited state. Long-lived emissive center was observed due to this MLCT-based decay and the help from π-π stacking. Such long-lived emissive state and the large conjugation planes in these complexes offered enough collision probability with O2 molecules, making themselves potential oxygen sensing probes. These six complexes were then doped into silica supporting matrix MCM-41 spheres. The resulting composite samples and their emission sensing response towards O2 were discussed in detail. The optimal sample showed sensitivity as high as 7.80 with response time of 14 s. A careful discussion between Cu(I) complex molecular structure and sensing performance was performed. It was concluded that both a long lifetime and a large conjugation plane lead to improved sensing sensitivity since they increased the collision probability with O2 molecules. On the other hand, it was found that both sensing response and recovery times were mainly controlled by O2 diffusion in supporting matrix.

  chains (short π chain, modest π chain and long π chain) were selected. A systematical comparison between these Cu(I) complexes was performed, so that the correlation between NN structure and [Cu(NN)(PPh3)2] photophysical performance was tentatively discussed. Their single crystal structure was found consistent with literature ones, forming a typical tetrahedral coordination geometry. Density functional

  在这项工作中，我们设计了一系列[Cu（N N）（PPh 3）2 ] BF 4配合物，它们具有不同的光学边缘值和发射色，从蓝色到红色，其中N N和PPh 3表示二胺配体和三苯基膦，分别。选择了六个具有各种共轭链（短π链，中等π链和长π链）的N N配体。对这些Cu（I）配合物进行了系统的比较，从而使N N结构与[Cu（N N）（PPh 3）2初步讨论了光物理性能。发现它们的单晶结构与文献中的一致，形成典型的四面体配位几何形状。密度泛函理论计算表明，它们的起始电子跃迁表现出金属到配体电荷转移和配体到配体电荷转移的混合特征。光物理参数的详细分析表明[Cu（N N）（PPh 3）2 ] BF 4的吸收边缘通过在二胺配体中的缀合长度来控制复合物。宽的吸收边缘需要二胺配体中的短共轭链。对于它们的发射光谱发现类似的趋势。此外，二胺配体中的长共轭链明显加宽了发射光谱。由于激发态主要受二胺配体的动力学过程和空

  In this paper, a diamine ligand of dipyrido[3,2-a:2',3'-c]phenazine (DPPZ) and its corresponding Cu(I) complex with triphenylphosphine (PPh3) as the phosphorous ligand are synthesized. Full characterization on [Cu(DPPZ)(PPh3)(2)]BF4, including NMR, elemental analysis and single crystal analysis, confirms its molecular identity. Upon photon excitation, the emission of [cu(DPPZ)(PPh3)(2)]BF4 owns a long excited state lifetime of similar to 6 mu s and shows a maximum intensity at 616 nm, under pure N-2 atmosphere. Theoretical calculation on [cu(DpPZ)(PPh3)(2)]BF4 single crystal suggests that the excited state has a triplet metal-to-ligand-charge-transfer character. By embedding [Cu(DPPZ)(PPh3)(2)]BF4 into a polymer supporting matrix of polystyrene, the emission signal is found to be sensitive towards varying oxygen concentrations, with a maximum sensitivity of 3.78. We attribute this sensitivity to the large conjugation plane in DPPZ ligand which can increase the population of excited state electrons and favor the oxygen attack on [Cu(DPPZ)(PPh3)(2)]BF4 excited state. Due to the porous structure of nanofibrous polystyrene matrix, a short response time of similar to 16 s towards molecular oxygen is also observed with stable quenching signal. (C) 2012 Elsevier B.V.
