<p>Cholesterol-based Schiff base <b>1</b> has been designed and synthesised. The Schiff base <b>1</b> forms yellow coloured gel in DMF:H<sub>2</sub>O (2:1, v/v) and the gel is anion responsive. Among different anions, the gel phase of <b>1</b> is selectively transformed into sol in the presence of CN<sup>–</sup> ions and validates its visual sensing. <sup>1</sup>H NMR, FTIR and HRMS spectroscopic techniques were adopted to study the gelation of <b>1</b> and its responsive behaviour towards anions.</p> <p>Cholesterol-based Schiff base <b>1</b> has been designed and synthesized.
