showed excellent gelation ability in alkane solvents. IR spectra of the gel clearly showed the absence of hydrogen bonding interaction at the C(6)O position and, together with a CD study, a G–G base pair formation by double N(2)H⋯N(3) and additional N(2)H⋯O(2′) hydrogen bonds was indicated. X-ray diffraction and SEM studies of the xerogel and AFM observation of the transferred gel suggested the formation
