The molecules involving azo and imino functional groups can coordinate with Hg2＋ to result in a large blue shift from 453 to 363 nm corresponding to a notable color change from orange to pale yellow in aqueous methanol solution (H2O/CH3OH＝1/4, V/V), which can be applied to naked eye detection of Hg2＋.

这些传感器分子包含偶氮和亚胺功能基团，在水/甲醇溶液（体积比1/4）中，可以与汞离子配位，使紫外-可见光谱中吸收峰发生由453到363 nm的蓝移，引起一个明显的溶液由橙色到淡黄的颜色变化。因而，这些传感器有肉眼检测汞离子的潜在应用。

The intramolecular hydrogen bonding can extend the ligand planarity and increase the intercalative ability of the complex to DNA. It is concluded that the torsion between the aromatic rings of ligands, due to introduction of the bulky substituent, results in the complexes only to partially or non-classically intercalate into DNA.

The impact of temperature,pH and ionic strength on the volume phase transition of the hydrogels is studied.The result shows that the volume phase transition temperature of ionizable and thermosenstive copolymer hydrogels depend upon the hydrophilic/hydrophobic character of the comonomers...

结果表明，疏水基末端端基的疏水程度决定凝胶体积相变的速率，随着疏水性单体甲基丙烯酸酯烷基链的增长，凝胶的疏水性增强，凝胶的相转变pH向低pH处迁移；温度高于LCST时，分子间的氢键作用减弱，疏水基团间的相互作用加强，凝胶发生体积相变。
