Enhanced Small-Molecule Assembly through Directional Intramolecular Forces
摘要:
Directional intramolecular interactions play a critical role in the self-assembly of donor-or-acceptor molecules in solution. Amide functions on the periphery of the tricyclic core stabilize a C-3-symmetric monomer conformation by intramolecular hydrogen bonding and dipole-dipole interactions. The molecules are effective organogelators and show long-range ordering in the bulk.

structure and reactivity that can accompany the donor-acceptor arrangement in rigid beta-aminoketones. X-ray structural analysis of trione 6 and dione 7 reveals bond length and angle variations consistent with through-bond (hyperconjugative) donor-acceptor interactions. Observed is a shortening of the C-N bond, elongation of the central C-C bond (to approximately 1.6 A), and a significant pyramidalization
