Organic light emitting diodes40 min.
ChemistryMacromolecular ChemistryFunctional polymers
Organic light emitting diodes (OLED) enable the construction of very flat, flexible and energy-saving displays. They consist of one or more thin organic semiconductor films between two electrodes. Light-emitting organic materials light up brightly when a current passes through them. The principle of operation of these diodes is explained.
Polyacetylene - an example of conductive polymers40 min.
The principle of conductive polymers is explained using the example of polyacetylene. Shirakawa, MacDiarmid and Heeger received the Nobel Prize in Chemistry in 2000 for their work on this topic. Since polyacetylene is not very stable in air, other conductive polymers with better properties were sought. Some of them are presented.
Atomic crystals45 min.
Atomic crystals can be divided into three structure types: spatial structure, layer structure and chain structure. This learning unit deals specifically with the electrical conductivity of the various atomic crystals.
