New dimeric cholesteryl-based A(LS)2 gelators with remarkable gelling abilities: Organogel formation at room temperature

► Three new A(LS)2 compounds prepared can act as efficient gelators. ► A small difference in the structures is crucial to the gelation behaviors of gelators. ► Sixteen gel systems can form spontaneously at room temperature (∼25 °C). ► The gels formed at room temperature possess smart thixotropic properties.
