A new lyotropic liquid crystalline phase formed in hydrocarbon solvents by a deoxyguanosine derivative through extensive hydrogen bonding

Abstract
Lipophilic deoxyguanosine 1 in pure hydrocarbons or in mixed CHCl3-hydrocarbon solvents forms a new lyotropic liquid crystalline phase characterized by a two dimensional square packing. The structural elements of the phase are ribbon-like assembled species which are completely different from the columnar structures, based on G-quartets, which are the building blocks of the mesophases formed by deoxyguanosine oligonucleotides in water.
