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。
