  • Collection: Supramolecular Chemistry

Poly(methyl methacrylate) end-functionalized with hexabenzocoronene as an effective dispersant for multi-walled carbon nanotubes.

We demonstrate that MWCNTs can be dispersed in common organic solvents as single tubes using a single hexabenzocoronene (HBC) unit at the end of a poly(methyl methacrylate) (PMMA) chain. The concentration of the HBC-based additive needed to disperse…

Effect of Side Chains on Charge Transfer in Quaterthiophene-Naphthalene Diimide Based Donor-Bridge-Acceptor Dyads

We have probed the effect of side chains on the charge transfer dynamics in dyads containing quaterthiophene (QT) donor and naphthalene diimide (NDI) acceptor. The donor and the acceptor are covalently linked using a flexible linker. Four dyads (1-4)…

Segregated assemblies in bridged electron-rich and electron-poor pi-conjugated moieties

We report a general strategy for the spontaneous segregation of electron-rich and electron-poor pi-conjugated moieties using mutually phobic aliphatic fluorocarbon-hydrocarbon interactions.

Helix versus zig-zag: control of supramolecular topology via carboxylic acid conformations in ortho-substituted phenyl amines

ortho-Substituted phenyl amines form supramolecular helices or zig-zag structures, depending on the conformation of the carboxylic acid substituents - which can be controlled by an intramolecular hydrogen-bonding interaction.

Spontaneous assembly of a hydrogen-bonded tetrahedron

Triphenylamine ortho-tricarboxylic acid (1) has been synthesized and the crystal structure reported. This molecule is shown to spontaneously self-assemble into a hydrogen-bonded tetrahedron. Furthermore, Electrospray Ionization Mass Spectroscopy…

9,10-bis{2-[4-(N,N-diphenylamino)phenyl]ethynyl}anthracene

The crystal structure of the title compound, C54H36N2, shows that the anthracene rings in the unit cell do not stack in a face-to-face manner. Instead, the anthracene rings are positioned over the planar N atom of the triphenylamino group.

Silver(I) complexes of 1,4-dicyanobenzene

The crystal structures of the complexes of 1,4-benzenedinitrile with silver(I) trifluoromethanesulfonate, catena-poly[{mu-(aqua-O, O)-bis[(trifluoromethanesulfonato-O)silver(I)]}…

Coordination networks based on multitopic ligands and silver(I) salts: A study of network connectivity and topology as a function of counterion

We show that much like hgdrog en bonding, Ag-N coordination bonds can be reliably used for the construction of supramolecular networks. From a solid-state structural study of silver(I) complexes of multitopic ligands, we describe coordination…

Exchange properties of the three-dimensional coordination compound 1,3,5-tris(4-ethynylbenzonitrile)benzene center dot AgO3SCF3

Properties such as guest removal and exchange within a host crystal are investigated for benzene . 1,3,5-tris(4-ethynylbenzonitrile)(1). silver triflate(AgOTf) (polymorph A). The 15 Angstrom x 22 Angstrom channels in the crystal structure are…
