28. 2 but they were not applied to the organogel system. More recently, Stoddart et al. synthesized sugar-coated discotic liquid crystals bearing a triphenylene core. The gelation properties were not examined therein: Barbera, J.; Garces, A. C.; Jayaraman, N.; Omenat, A.; Serrano, J. L.; Stoddart, J. F. Adv. Mater. 2001, 13, 175-180.
29. More recently, we found that certain cholesterol-appended porphyrins act as gelators of organic solvent: Ishi-i, T.; Jung, J. H.; Shinkai, S. J. Mater. Chem. 2000, 10, 2238-2240. Tian, H. J.; Inoue, K.; Yoza, K.; Ishi-i, T.; Shinkai, S. Chem. Lett. 1998, 871-872. In these organogels, however, it is considered that porphyrin moieties are located around a helical central colmun of cholesterol moieties, like a spiral staircase.
