合成了一系列具有C3v对称性、下缘分别利用Se,Te和S杂原子连接蒽环发光基团的杯[6]芳烃衍生物(1～3).通过紫外-可见光谱和荧光光谱研究了它们对各种碱金属离子和过渡态金属离子的化学传感识别行为.结果表明,含有Se杂原子的主体1在CH2Cl2溶液中对Hg2+表现出了良好的选择性.通过肉眼可直接观察到溶液颜色由无色变为黄色.通过荧光光谱的连续滴定实验,主体1-Hg2+体系的稳定常数可达(1.12±0.08)×105 L/mol.因此,化合物1有望成为一种用于检测Hg2+的新型化学传感器.
A series of calix [6] arene derivatives (1 ~ 3) with C3v symmetry and the lower edge connected anthracene ring luminescent groups with Se, Te and S heteroatoms were synthesized respectively. The UV-Vis and fluorescence spectra of Their chemical sensing recognition of various alkali metal ions and transition metal ions showed that the host 1 containing Hetero-Se atoms showed a good selectivity for Hg 2+ in CH 2 Cl 2 solution, which could be directly observed by the naked eye The color changes from colorless to yellow, and the stability constant of the 1-Hg2 + system can reach (1.12 ± 0.08) × 105 L / mol by continuous titration experiment.From this point, New chemical sensor.
