Mixtures of two solvents allow obtaining stable physical gels of syndiotactic polystyrene (s-PS), whose physical knots are for the first time constituted by e cocrystals. These e gels, by simple scCO(2) extraction procedures, lead to aerogels only exhibiting the nanoporous-crystalline e form, with a degree of crystallinity higher than 45%. This preparation procedure is the first one leading to pure e form aerogels. Although the BET surface areas for e aerogels (exhibiting crystalline nanochannels) are much lower than for delta form aerogels (exhibiting isolated crystalline nanocavities), the uptake of long organic molecules is definitely higher for epsilon aerogels, with differences becoming very high at low guest pressures. Moreover, for all guests, pure e aerogels present uptakes significantly higher than the previously known epsilon + gamma aerogels.
