Methoxy functionalisation: exerting synthetic control of the supramolecular and electronic structure of nitrogen-doped nanographenes.
We describe a series of functionalized N-containing heterosuperbenzenes, created with a view to investigating the strategic role of methoxy substituents in (i) promoting cyclodehydrogenation and (ii) tuning the electronic properties and (iii) the supramolecular order in the resultant fused products.
متن کاملTwo new chalcones from the flowers of Clerodendrum inerme.
Two new chalcones, 3-hydroxy-3',4'-dimethoxychalcone (1) and 3,2'-dihydroxy-3',4'-dimethoxychalcone (2), were isolated from the flowers of Clerodendrum inerme (L.) Gaertn together with two known flavones, 7-O-methylwogonin (3) and eucalyptin (4). The structures of the new compounds 1 and 2 have been established by extensive 2D-NMR and ESI-TOFMS studies.
متن کاملTwo-dimensional soft supramolecular networks.
Two flexible multivalent molecular units are employed to self-assemble highly regular supramolecular porous networks at the solid/liquid interface. Scanning tunnelling microscopy imaging corroborated with molecular dynamics simulations make it possible to elucidate the conformational freedom behind the binding motif, which identify the architecture as a highly regular soft network.
متن کاملDNA as a supramolecular scaffold for the helical arrangement of a stack of 1-ethynylpyrene chromophores.
A highly organized helical pi-stacked arrangement of 1-ethynylpyrene moieties along the major groove of duplex DNA can only be achieved if more than three chromophores have been synthetically incorporated adjacent to each other.
متن کاملSupramolecular aggregation of two hydroxycarboxylic acid derivatives.
The crystal structures of 7,7-dicyclobutyl-5-hydroxymethyl-6-oxabicyclo[3.2.1]octane-1-carboxylic acid, C17H26O4, (I), and 1-(hydroxymethyl)-7-oxaspiro[bicyclo[3.2.1]octane-6,1'-cyclopentane]-5-carboxylic acid, C13H20O4, (II), determined at 170 K, show that the conformation of the hydroxymethyl group (anti or gauche) affects the dimensionality (one- or two-dimensional) of the supramolecular str...
