Electroluminescent materials

Electroluminescent polymers

Electroluminescent polymers are reviewed in terms of synthesis and relationships between structure and light emission properties. The main concepts, problems and ideas related to the subject as a whole and to each class of electroluminescence (EL) polymer, have been systematically addressed. The elements of device architecture were considered, such as electrode characteristics and transport lay...

Variability of Electroluminescent Displays

Carbazole dendronised triphenylamines as solution processed high Tg amorphous hole-transporting materials for organic electroluminescent devices.

Carbazole dendrimers up to 4th generation were synthesized. They showed significantly high T(g), amorphous and stable electrochemical properties, and great potential as solution processed hole-transporting materials for OLEDs. Alq3-based green devices exhibited high luminance efficiency and CIE coordinates of 4.45 cd A(-1) and (0.29, 0.53), respectively.

1,2-dihydrophosphete: a platform for the molecular engineering of electroluminescent phosphorus materials for light-emitting devices.

The discovery and molecular engineering of novel electroluminescent materials is still a challenge in optoelectronics. In this work, the development of new π-conjugated oligomers incorporating a dihydrophosphete skeleton is reported. Variation of the substitution pattern of 1,2-dihydrophosphete derivatives and chemical modification of their P atoms afford thermally stable derivatives, which are...

A Comparative Analysis of Electroluminescent and Retrorefelective Materials as Nighttime Pedestrian Conspicuity Aids

Recent literature suggests that retroreflective materials, when configured in a biological motion pattern, make vulnerable road users (such as pedestrians) more conspicuous to drivers at night. However, retroreflective elements in clothing can be effective only when a light source (e.g., automobile headlamps) illuminates the material in such a way as to allow the material to reflect sufficient ...
