Abstract
Appending perfluoroalkyl substituents to bis(urea) gelators results in significantly decreased interchain interactions with markedly thinner fibres and hence more cross-linked and more transparent gels with potential applications in the crystallisation of fluorinated pharmaceuticals. Gel structure has been probed be detailed SANS measurements which indicate a surprise structure evolution on thermal cycling, not seen for hydrocarbon analogues. The SANS data are complemented by the single crystal X-ray structure of one fluorinated gelator.Citation
