Abstract
2-Thiobarbituric acid-functionalized naphthalene dye selectively self-assembles into crystalline fibers to show material properties that are different from those of a previously reported oxo-barbituric acid derivative affording curved supramolecular polymers via the formation of hydrogen-bonded rosettes. Detailed studies using 1H-NMR, DFT calculation and X-ray diffraction revealed that the crystalline fiber is formed through a tape-like hydrogen-bonding pattern due to the weaker hydrogen-bond-acceptor ability of the thiocarbonyl group.
