摘要
设计合成了基于萘啶类衍生物1,2-二(7-氯-1,8-萘啶-2)-肼(H2L)及其双硼核化合物C1.H2L的光谱性质具有明显的溶剂效应,它的发光很弱,而C1的发光很强,荧光量子产率超过90%.H2L在甲醇中不稳定,其相应的光谱特征蓝移到萘啶的特征峰,但金属离子Hg2+和Zn2+的引入能够恢复H2L的特征峰.通过溶剂挥发的方法得到了C1的单晶.结构研究表明,在其晶胞中分子间通过C3-H3…F1和C3-H3…F2氢键作用形成三维网格结构.
The hydrazine ligand （H2L） bearing naphthyridine moieties and its bis-BF2 （Cl） compound were designed and synthesized. The crystal structure analysis of C1 revealed that molecules in the cell were linked by C3-H3.F1 and C3-H3.-F2 hydrogen bonds to form a 3D network structure. Spectroscopic properties of H2L are sensitive to solvents. The absorption spectrum of HaL in MeOH was blue-shifted with respect to that in CH2C12, and which can be restored upon addition of metal ions. C1 exhibits intense fluorescence in MeOH with a quantum yield of 0.92.
