A unique transformation from a heat-set organogel to a room-temperature organogel induced by ethanol (EtOH) was reported here. When the system containing β-cyclodextrin, 4,4′-isopropylidenediphenol, N,N-dimethylacetamide and LiCl was heated to the gelling temperature (Tgel), a heat-set organogel would be formed. In contrast, a semitransparent organogel (room-temperature organogel) could be obtained...
This paper describes the first example of controllable transformation from sensitive and reversible heat-set organogel to stable gel induced by sodium acetate. Upon the addition of proper amount of acetate sodium into the reversible heat-set organogel system composed of β-CD, phenolphthalein (PP) and lithium chloride in N,N-dimethylformamide, the reversible gel could transform to stable gel as the...
