Double‐stranded helical crystals with high axial ratio are prepared from a cholic acid ester. Two processes are involved in the formation of the micrometer‐scale self‐assembled crystals: 1) the self‐assembly of the cholic acid ester to form a hydrogel (the formation of gel fibers); 2) the winding of the gel fibers (laser confocal scanning micrographs show, top: left‐handed; bottom: right‐handed).
