Shedding light on pi-conjugation

摘要

Designing molecules with tailored photochemical properties could be possible thanks to computational chemists in Germany.Pi-conjugated compounds have alternating single and multiple bonds in their structure.Their electrons are delocalised over the system and the optical and electronic properties of the materials ar e influenced by the strength of this conjugation.These materials can find use in organic light emitting diodes and molecular switches that are activated photochemically.
