Abstract

ABSTRACT: Rosette nanotubes (RNTs) are tubular architectures generated through the hierarchical self-assembly of the guanine-cytosine (G∧C) motif1 or2 (Figure 1). Motif2 differs from1 by the substitution at the N-atom in the G-ring with a C-atom as shown in red. In this paper, we prepare a new tricyclic G∧C base3 from a functionalized derivative of2 and demonstrate its self-assembly into fluorescent helical RNTs in N, N -dimethylformamide (DMF). The self-assembly and fluorescent properties of RNTs3 were established using scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM) and UV-visible spectroscopy.
