Supramolecular Macrostructures of UPy-Functionalized Carbon Nanotubes Article uri icon

abstract

  • Carbon nanotubes (CNTs) are considered excellent materials for the construction of flexible displays due to their nanoscale dimensions and unique physical and chemical properties. By using the recognition properties of 2-ureido-4[1H]pyrimidinone (UPy), a versatile and simple methodology was demonstrated for the construction of macroscopic structures based on UPy-CNT/polymer composites prepared by a combination of two functionalization approaches: 1)covalent attachment of UPy pendants on the multiwalled CNT surface (UPy-MWCNTs) and 2)directed self-assembly of UPy-MWCNTs within polymers bearing UPy pendants (Bis-UPy1 and Bis-UPy2) by quadruple complementary DDAA-AADD hydrogen-bond recognition (D=donor, A=acceptor). Novel carbon nanotube materials stabilized by quadruple hydrogen-bonding interactions (see figure) have been synthesized. By using the recognition properties of 2-ureido-4[1H]pyrimidinone (UPy), a versatile and simple methodology was demonstrated for the construction of macroscopic structures based on UPy-CNT/polymer composites prepared by a combination of two functionalization approaches. © 2015 WILEY-VCH Verlag GmbH %26 Co.
