Hybrid Microstructures: One-Dimensional Microwires Formed by the Co-Assembly of Complementary Aromatic Donors and Acceptors (Adv. Funct.

ADVANCED FUNCTIONAL MATERIALS, Issue 11 2009
Mater.
A complementary donor-acceptor pair of truxene derivatives, Tr3 and its oxidized counterpart TrO3, are presented by Pei et al. on page 1746, and used to build a foundation for the investigation of aromatic donor,acceptor interaction. Two-component one-dimensional microstructures are realized by a simple solution process reliant on this interaction. Such a hybrid material opens new possibilities in the future design of multicomponent organic nano- and microstructures. [source]

One-Dimensional Microwires Formed by the Co-Assembly of Complementary Aromatic Donors and Acceptors

ADVANCED FUNCTIONAL MATERIALS, Issue 11 2009

Abstract A truxene derivative (Tr3) with a C3 symmetric conjugated plane is synthesized; this derivative is a perfect match, in both size and structure, with its oxidized counterpart, the truxenone derivative (TrO3), a new electron acceptor that was recently reported. The complementary pair, Tr3 and TrO3, sets a good platform for the investigation of aromatic donor,acceptor interactions. Detailed 1H NMR experiments, photoluminescence spectroscopy, as well as differential scanning calorimetry are performed to investigate the interaction between Tr3 and TrO3, from solution to mesophase. One-dimensional microbelts readily formed from a 1:1 mixture of Tr3 and TrO3. Scanning electron microscopy, powder X-ray diffraction, as well as fluorescence microscopy are performed to elucidate their co-assembly structure in the solid state. Moreover, modulation of the co-assembly structure is easily realized by changing the concentration or mixing ratio. The present system opens the possibility of forming 1D heterostructures via electron donor,acceptor interaction, and its potential application as P,N junction and photowaveguide materials in optoelectronic devices.

Composites of Graphene with Large Aromatic Molecules

ADVANCED MATERIALS, Issue 31 2009
Qi Su
A novel approach to functionalize graphene with large aromatic donor and acceptor molecules consisting of nanographene units is presented, producing an unprecedented class of graphene and nanographene composites with tunable electronic properties. The stability of aqueous dispersion of graphene sheets is greatly enhanced, and a large number of monolayer and double-layer graphene sheets could be facilely fabricated on the substrates [source]
