Highly ordered assembly of π-stacked distyrylbenzenes by oligoadenines.
A well-defined nanofibrous structure with lengths of several hundred nanometers and cross-sectional width of a single size (∼6 ± 0.5 nm) was self-assembled by oligoadenines, dA(20), and thymine-appended distyrylbenzene through binary complementary A-T hydrogen bond formation and the strong π-π stacking interactions. This demonstrated a useful supramolecular self-assembling approach to control the packing order of π-conjugated molecules and provided a practical means to enhance the optical properties of a material.
