Five novel fluorescent Schiff base tin(IV) complexes of the type [SnCl3(L)] were synthesized and their properties were investigated: the emission wavelengths range from bluish green to orange (λmax: 492–545 nm). DFT calculation shows that the order of the magnitudes of HOMO–LUMO gaps is consonant with that of the emission wavelengths (λmax) of the complexes, and good correlation was observed between reduction potentials in DMSO and the energies of LUMO.
合成了五种新型荧光席夫碱
锡(IV)配合物,其类型为[SnCl₃(L)],并研究了它们的性质:这些配合物的最大发射波长范围从蓝绿色到橙色(λmax:492-545 nm)。DFT计算表明,最高占据分子轨道(HOMO)与最低未占据分子轨道(LUMO)之间的能隙大小顺序与配合物的最大发射波长(λmax)顺序一致,在
二甲基亚砜(
DMSO)中观察到了还原电位与LUMO能级之间的良好相关性。
