Self-assembly and conductivity of hydrogen-bonded oligothiophene nanofiber networks.

چکیده
Symmetric oligothiophene derivatives containing hydrogen bond forming segments create self-supporting organogels consisting of self-assembled 1D nanostructures at low concentrations. Hydrogen bond formation and π-π stacking were both found to be crucial for the formation of conductive supramolecular networks of 1D nanostructures.

Self-assembly and semiconductivity of an oligothiophene supergelator
A bis(trialkoxybenzamide)-functionalized quaterthiophene derivative was synthesized and its self-assembly properties in solution were studied. In non-polar solvents such as cyclohexane, this quaterthiophene π-system formed fibril aggregates with an H-type molecular arrangement due to synergistic effect of hydrogen bonding and π-stacking. The self-assembled fibres were found to gelate numerous o...
متن کاملTemplated bilayer self-assembly of fully conjugated π-expanded macrocyclic oligothiophenes complexed with fullerenes
Fully conjugated macrocyclic oligothiophenes exhibit a combination of highly attractive structural, optical and electronic properties, and multifunctional molecular thin film architectures thereof are envisioned. However, control over the self-assembly of such systems becomes increasingly challenging, the more complex the target structures are. Here we show a robust self-assembly based on hiera...

Electrically conducting hexagonally self-assembled nanostructures of poly(aniline) (PANI) protonated with 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPSA) and hydrogen bonded with resorcinol (res), 4-ethylresorcinol (C2res) or 4-hexylresorcinol (C6res) are studied. Small-angle X-ray scattering (SAXS) of PANI(AMPSA)0.5(Cnres)y with y ) 0, ..., 1.5 indicate cylindrical self-assembly in all ca...
متن کاملSelf-Assembly through Hydrogen Bonding: Peripheral Crowding-A New Strategy for the Preparation of Stable
The self-assembly of two new types of stable hydrogen-bonded supramolecular aggregates-bisrosettes-that are based on parallel, connected CA3.M3 rosettes is reported. The minimization of intermolecular steric hindrance-peripheral crowding within the aggregate-is proposed as the structural feature responsible for selecting the cyclic CA3'M3 rosette over competing linear hydrogen-bonded networks a...
متن کاملQuantum Chemical Investigations on C14C10-Branched-Chain Glucoside Isomers Towards Understanding Self-Assembly
Density Functional Theory (DFT) calculations have been carried out using a Polarizable Continuum Model (PCM) in an attempt to investigate the electro-molecular properties of branched-chain glucoside (C14C10-D-glucoside) isomers. The results showed that αconfiguration of pyranoside form is thermodynamically the most stable, while the solution should contain much more β...
