Self-Assembly of a Chiral Pyrene-Bifuran-Imide Into Helical and Spherical Nanostructures.
We report the solvent-dependent self-assembly of 1-Py2, a novel bifuran-imide building block functionalized with terminal pyrene units and an enantiopure, alanine-derived chiral side chain. In pure tetrahydrofuran, 1-Py2 exists as a monomer with no electronic circular dichroism (ECD) signal. Increasing the water conten...
