    Self-sorted Oligophenylvinylene and Perylene Bisimide Hydrogels


    Castilla, AM, Draper, ER, Nolan, MC, Brasnett, C, Seddon, A, Mears, LLE, Cowieson, N & Adams, DJ, 2017, ‘Self-sorted Oligophenylvinylene and Perylene Bisimide Hydrogels’. Scientific Reports, vol 7.


    We describe two component hydrogels with networks composed of self-sorted fibres. The component gelators are based on 1,4-distyrylbenzene (OPV3) and perylene bisimide (PBI) units. Self-sorted gels can be formed by a slow decrease in pH, which leads to sequential assembly. We demonstrate self-sorting by NMR, rheology and small angle X-ray scattering (SAXS). Photoconductive xerogels can be prepared by drying these gels. The wavelength response of the xerogel is different to that of the PBI alone.
