A novel azo-thiourea basedanionreceptor can be synthesized by coupling a bis-azoaniline motif with butyl isothiocyanate with 45% yield under mild conditions. It was found that azo-thiourea was an excellent receptor to recognize various di-carboxylate anions. It can serve as a colorimetric sensor for azelate ion and led to a significant change in the absorption spectrum. Furthermore, a reversible
可以通过在温和的条件下将双偶氮苯胺基序与异硫氰酸丁酯偶合以45%的收率来合成新型的基于偶氮硫脲的阴离子受体。发现偶氮硫脲是识别各种二羧酸根阴离子的优良受体。它可以用作壬二酸根离子的比色传感器,并导致吸收光谱的显着变化。此外,通过1 H NMR光谱证实了可见光诱导的偶氮硫脲可逆的顺式-顺式异构化。

photoisomerization of azobenzenes provides a general means for the photocontrol of molecular structure and function. For applications in vivo, however, the wavelength of irradiation required for trans-to-cis isomerization of azobenzenes is critical since UV and most visible wavelengths are strongly scattered by cells and tissues. We report here that azobenzene compounds in which all four positions ortho to the azo
