合成了水杨醛缩席夫碱衍生物N-水杨醛缩（S）-α-萘乙胺（SNEA），研究了其多态/多功能开关的性质。在光输入（紫外光和可见光）和化学输入（pH和Zn ~（2+））的刺激下，SNEA发生可逆的光致变色、去质子化和络合反应。在这种情况下，涉及四种化学物质。利用吸收光谱和发射光谱系统地研究了SNEA在四个态之间的相互转换。光谱研究表明，SNEA单分子可以实现光致变色开关、pH开关和荧光开关。
The salicylidene Schiff base derivative, namely, N-salicylidene-(S)-α-naphthylethylamine (SNEA) has been synthesized to study the characterization of multistate/multifunctional switches. Upon the stimulations of optical inputs (UV light and visible light) and chemical inputs (pH and Zn2+), SNEA undergoes reversible photochromism, deprotonation and complexation reactions. In this case, four chemical species are involved. These interconversions of SNEA between four states have been systematically investigated by the absorption and the emission spectra. Spectroscopic studies indicate that the photochromic switch, pH switch and fluorescent switch can be realized using the single molecular entity of SNEA.
