  摘要：

  一系列三配位铜（I）配合物（L Me）CuX [X = Cl（1），Br（2），I（3）]，（L Et）CuBr（4）和（L iPr）CuBr （5）[L Me＝ 1,2-双[双（2-甲基苯基）膦基]苯，L Et＝ 1,2-双[双（2-乙基苯基）膦基]苯，和L iPr＝ 1，2-双[双（双（2-异丙基苯基）膦基]苯]在环境温度下以473-517nm的峰值波长在固态下表现出有效的蓝绿色发射。发射量子产率为0.38–0.95。使用纳秒激光技术在77–295 K的温度范围内测量了发射寿命。使用具有两个激发态：单重态和三重态的模型来解释发射寿命的温度依赖性。两种状态之间的小能隙（<830 cm -1）表明从1-5发出的有效发射是热激活的延迟荧光（TADF）。邻位的烷基取代基发现外围苯基的位置对电子激发态几乎没有影响。因为配合物的发光的原点2，4，和5被认为是一个（σ+溴）→π*跃迁，这些络合物的光

  substituents than those of LMe, reacted with AgBr to give crystalline three-coordinate complexes (LEt)AgBr (2) and (LiPr)AgBr (3). Nuclear magnetic resonance (NMR) studies demonstrated that 1 dissociates in solution to yield a monomeric three-coordinate complex (LMe)AgBr. Luminescence studies showed that complexes 1–3 exhibit efficient blue thermally activated delayed fluorescence (TADF) in both solid

On the other hand, the bulkiest ligand, LiPr, affords three-coordinate Au(I) complexes, LiPrAuCl (3) and LiPrAuI (4), but no dinuclear complexes.

  The homoleptic complex [Ag(L)(2)]PF6 (1) and heteroleptic complexes [Ag(L)(L-Me)]BF4 (2) and [Ag(L)(L-Et)]BF4 (3) [L = 1,2-bis(diphenylphosphino)benzene, L-Me = 1,2-bis[bis(2-methylphenyl)phosphino]benzene, and L-Et = 1,2-bis[bis(2-ethylphenyl)phosphino]benzene] were synthesized and characterized. X-ray crystallography demonstrated that 1-3 possess tetrahedral structures. Photophysical studies and time-dependent density functional theory calculations of 1-3 revealed that alkyl substituents at the ortho positions of peripheral phenyl groups in the diphosphine ligands have a significant influence on the energy and intensity of phosphorescence of the complex in solution at room temperature. The results can be interpreted in terms of the geometric preferences of each complex in the ground and excited states. The homoleptic complex 1 exhibits weak orange phosphorescence in solution arising from its flat structure in the triplet state, while heteroleptic complexes 2 and 3 show strong green phosphorescence from triplet states with tetrahedral structure. Larger interligand steric interactions in 2 and 3 caused by their bulkier ligands probably inhibit geometric relaxation within the excited-state lifetimes, leading to higher energy phosphorescence than that observed for 1. NMR experiments revealed that 2 and 3 in solution possess structures that are much more immobilized than that of 1; fluxional motion is completely suppressed in 2 and 3. Accordingly, conformational changes of 2 and 3 are expected to be suppressed by the alkyl substituents not only in the ground state but also in excited states. Consequently, nonradiative decay of the excited states of 2 and 3 occurs less efficiently than in 1. As a result, the quantum yields of phosphorescence for 2 and 3 are 6 times larger than that for the homoleptic complex 1.
