Enlightening solutions

Article Abstract:

White-light-emitting diodes are becoming increasingly important and multi-layer organic devices grown from solution offer bright prospects. The development of organic light-emitting diodes assures further innovation in the field and such diodes are light-weight, provide high brightness at low power and can be fabricated on flexible substrates to form thin devices at potentially low production cost.

Visualizing single-molecule diffusion in mesoporous materials

Article Abstract:

A combination of electron microscopic mapping and optical single-molecule tracking experiment that reveals a single luminescent dye molecule traveling through linear or strongly curved sections of a mesoporous channel system is presented. The structure and dynamics of porous materials and host-guest systems could used to study bioactive molecules in porous materials for drug delivery.

Improving the performance of doped pi-conjugated polymers for use in organic light-emitting diodes

Article Abstract:

It has been established that 'hole-only' and organic light-emitting diode devices using highly-doped poly(4,4'-dimethoxy-bithiophene) (PBDT) anodes show strongly reduced onset fields compared with those using non-doped PDBT, indium tin oxide or commercially available poly(3,4-ethylenedioxythiophene) as the anode.
