A novel method for the synthesis of bile-acid-based polymers has been developed using click chemistry. These 1,2,3-triazole-containing polymers have been found to stabilize silver nanoparticles that show selective colorimetric sensing for iodide ion.
Copper-Catalyzed [1,3]-Dipolar Cycloaddition for the Synthesis of Macrocycles Containing Acyclic, Aromatic and Steroidal Moieties
bis(cholane)-24,24′-diazides with aliphatic dipropargyl esters, or bis(cholane)-24,24′-dipropargyl esters with aromatic diazides, or by cyclization-dimerization of bile acid derivatives possessing both azide and acetylene groups in the same molecule. 1,3-dipolar cycloaddition - azides - cholaphanes - copper - macrocycles

Based on a topochemical approach, a strategy for efficiently producing main-chain poly(bile acid)s in the solid state was developed. This strategy allows for facile and scalable synthesis of main-chain poly(bile acid)s not only with high molecular weights, but also with quantitative conversions and yields.
