Thermoreversible gelation of organic liquids by arylcyclohexanol derivatives Synthesis and characterisation of the gels

Geminal Bis-ureas as Gelators for Organic Solvents: Gelation Properties and Structural Studies in Solution and in the Gel State

“…[11] The melting point determined by the dropping ball method lies approximately 10 8C below the maximum of the DSC melting endotherm, and therefore the evaluation of these data by a phase-separation model or Schraders equation, which describes ideal solubility behaviour, is not justified. [12,13,14] Furthermore, a gradual weakening of the gel is observed by the dropping ball method rather than a discrete phase transition, in complete agreement with the results from the DSC experiments.…”

On the Measurement of Phase Transition Temperatures in Physical Molecular Organogels

“…A parallel can be drawn (41) between the dissolution of crystals and the disaggregation of a solid-like network made up of numerous crosslinks (42). The description is certainly oversimplified and does not take into account the influence of the liquid, which may affect significantly the structures and thermodynamic behaviors (metastability, H values) (43). A comparison of the ln(φ) versus T profiles indicates that a better agreement with a linear variation is obtained with the γ method in contrast to both the tangent method as applied to G versus T plots (Fig.…”

1,2-O-(1-Ethylpropylidene)-α-d-glucofuranose, a low molecular mass organogelator: benzene gel formation and their thermal stabilities

“…1 does not take into account the influence of the solvent, which may affect the structures and thermodynamic behaviors. 21 Therefore, using Eq. 1 for describing the physical gel is probably oversimplified but is generally accepted.…”
