  三核间Cu⋯NPy弱配位键调节的三核Cu（I）-吡唑酸盐的发光多态聚集体

  摘要：

  三核Cu（I）-吡唑酸盐的五个发光多晶型聚集体，即[抗-Cu 3 L 3 ] 2（1），[合成-Cu 3 L 3 ·C 2 H 5 OH] 2（2），[抗-Cu 3 L 3 ·C 2 H 5 OH] n（3），[抗-Cu 3 L 3 ·0.5C 7 H 8 ] n（4）和[ syn -Cu 3 L 3 ·C 8 H 10 ] n（5）（H L＝ 4-（吡啶-4-基硫基）-3，5-二甲基-1 H-吡唑）被报道。三聚体Cu 3 L 3片段根据在Cu 3 Pz 3平面两侧（Pz =吡唑酸酯）的4-吡啶基的悬空方向呈现顺式和反式构象。三元间N Py ⋯Cu弱配位键将这些Cu 3 L 3结合在一起片段一起形成二聚体或聚合结构，通过结晶的溶剂分子或三聚体Cu⋯Cu相互作用进一步稳定。通过加热将结晶溶剂抽空，可以将溶剂化的配合物（3-5）转变为未溶剂化的配合物1。所有这些络合物在紫外线照射下从绿色发射到黄色，这是由于金属向配体电荷转移（3

  A pair of chiral CuI coordination polymers (1-P/M) were produced from achiral precursors by crystallization-driven symmetry-breaking assembly. The enantiomers feature unique helical layered structures and tunable dual-emission photoluminescence, achieving intrinsic “warm”-white emitting with an ultra-high color rendering index (93.4) and circularly polarized luminescence with a remarkable dissymmetry

  Three Cu₃Pz₃-based isostructural complexes (Cu₃L₃)₂(CuX)₂ (labeled as 1-ClO₄, 1-NO₃, and 1-Br, where X = ClO₄^-, NO₃^-, and Br^-, respectively) were prepared by solvothermal reactions of an angular bifunctional pyridyl-pyrazole ligand, 4-(pyridin-4'-ylthio)-3,5-dimethyl-1 H-pyrazole ( HL), with Cu(ClO₄)₂, Cu(NO₃)₂, and CuBr, respectively. Pyrazolate (Pz) groups are highly specific to form planar trinuclear Cu₃Pz₃ units. Two Cu₃L₃ units are further connected by two CuX units through N_Py-Cu-N_Py (Py = 4-pyridyl) bonds to form an octanuclear chairlike molecule (Cu₃L₃)₂(CuX)₂, which then self-assembles through intertrimeric cuprophilicity to construct chainlike supraaggregates featuring two luminophores, [Cu₃Pz₃]₂ and CuPy₂X. With different counteranions (ClO₄^-, NO₃^-, and Br^-), the complexes give off various emissions from red to green upon UV irradiation. 1-ClO₄ and 1-NO₃ show only low-energy (LE) orange (λ_em^max = 585 nm) and red (λ_em^max = 640 nm) emissions, while 1-Br exhibits excitation-dependent (260-360 nm) emissions from yellow to green due to variation in the relative intensities of two resolvable emissions, high energy (HE, λ_em^max = 520 nm) and LE (λ_em^max = 630 nm). The dual emissions are assigned to ³CC (LE states) based on excimeric [Cu₃Pz₃]₂ units and ³XLCT/³MLCT (HE states) based on CuPy₂X units. This work realizes a chemopalette effect through regulations of the counteranion and excitation energy in a dual-emissive system. It provides valuable insights into the nature of dual-emissive materials and the further investigation of the photophysical mechanism in such a system.
