The salicylidene Schiff base derivative, namely, N-salicylidene-(S)-alpha-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 Zn(2+)), 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.
水杨醛席夫碱衍生物，即N-水杨醛基-(S)-α-萘乙胺（SNEA）已被合成用于研究多态/多功能开关的特性。在光输入（紫外光和可见光）和化学输入（pH值和Zn(2+)）的刺激下，SNEA会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。通过吸收光谱和发射光谱系统地研究了SNEA在四种状态之间的这些相互转化。光谱研究表明，使用SNEA的单分子实体可以实现光致变色开关、pH开关和荧光开关。
