The low-molecular weight organogelator 2,3-di-n-decyloxyanthracene was synthezised and dissolved in dimethyl sulfoxide. With diffusion-ordered NMR spectroscopy, the temperature dependence of the diffusion coefficients was measured and a clear hysteresis of the gelation was observed between 320 and 330 K. This hysteresis was interpreted with respect to different entanglement behavior on heating and cooling. No alignment of the gelator with respect to the magnetic field was found despite its 14 pi-electrons.
