摘要
以[Cu(CH_3CN)_4](ClO_4)、1,1'-联萘-2,2'-双二苯膦(BINAP)和2-(2-苯并咪唑基)-6-甲基吡淀(Hbmp)为起始原料,合成得到一例铜(Ⅰ)单核配合物[Cu(Hbmp)(BINAP)](ClO_4)(1),并对其结构和光物理性质进行了表征。X-射线单晶衍射表明,配合物1的一价铜离子与Hbmp上的2个N和BINAP上的2个P相连接,产生一个以一价铜离子为中心的变形四面体。配合物1在340~450 nm范围有一个弱的低能量宽吸收,其归属于Cu(Ⅰ)到Hbmp的金属到配体电荷转移(MLCT)跃迁。配合物1在溶液和固态均具有良好的光致发光性质。
A mononuclear Cu(Ⅰ) complex [Cu(Hbmp)(BINAP)](ClO4)(1) was synthesized by using starting materials involving [Cu(CH3CN)4](ClO4),1,1’-binaphthal-2,2’-bisdiphenylphosphine(BINAP) and 2-(2-benzimidazolyl)-6-methylpyridine(Hbmp),and its structure and photophysical properties were investigated.As revealed by X-ray single-crystal diffraction,complex 1 exhibits a distorted tetrahedral geometry,where the Cu(Ⅰ) ion coordinates with two N atoms of Hbmp and two P atoms of BINAP.Complex 1 has a weak low-energy broad absorption peaking at 340~450 nm,which is attributable to metal-to-ligand charge transfer(MLCT) transitions from Cu(Ⅰ) to Hbmp.Complex 1 exhibits good photoluminescence properties in both solution and solid states.
