Conjugated polymers

Definition

Conjugated polymers are organic macromolecules that are characterized by a backbone chain of alternating double- and single-bonds. Their overlapping p-orbitals create a system of delocalised π-electrons, which can result in interesting and useful optical and electronic properties.

    The use of mechanical force to break and build chemical bonds in polymers can enable transformations that cannot be conducted using stimuli such as light and heat. Now, an insulating polymer has been mechanically unzipped to create a semiconducting polymer with extended regions of conjugation.

    Nature is the master in precision synthesis of macromolecules. In synthetic materials, achieving a high degree of structural precision is challenging and the influence of molecular defects on the properties of materials remains uncertain.

    Excitation of organic donor–acceptor systems with high-energy light can produce hot charge-transfer states that are delocalized across the heterojunction and readily dissociate. Two studies now reveal the dynamics of this process and pave the way towards unravelling the details of the molecular landscape that favours fast photocarrier generation.
