摘要
在氮气的保护下,以无水甲醇为溶剂合成了几种以chxn(chxn=1(R),2(R)-环己二胺)和en(en=乙二胺)为配体的镍配合物,单晶结构分析和元素分析确定其组成。并对其进行了UV-Vis吸收光谱、荧光光谱的测定和比较,结果表明镍的二价和三价配合物在紫外可见区吸收带的位置和强度明显不同,几种配体和配合物均具有较好的荧光性质,配体荧光图谱显示荧光发射峰在408 nm,荧光量子效率高,而合成的三价镍配合物荧光发射峰则紫移至360 nm左右。
A series of single crystals of the complexes of nickel hydrate with chxn（chxn =1（R）,2（R）-diaminocyclohexane） and en（en =ethylenediamine） were synthesized in dry N_2 atmosphere and absolute methanol.The composition and the crystal structure of the complexes were tested.The spectroscopic properties were compared using solid UV spectrophotometer and fluorescence spectrophotometer.The experimental results showed that the position and intensity of the UV absorption bands of the two and three valence nickel complexes were apparently different.The two ligands and compounds are all stable luminescence material.The two ligands emit intensive fluorescence at the peak wavelength of 408 nm,whereas the weaker emission of the three valence nickel complexes shifts to 360 nm.
