Congratulations to Abi Collins, Michael Bennison, Bolong Zhang and Rachel Evans whose paper has been published in Macromolecules. The perspective is entitled “Organic Polymer Hosts for Triplet–Triplet Annihilation Upconversion Systems”.

The impressive artwork for the perspective featured on the front cover of the issue was made by our own Kieran Richards.

In this perspective the authors discuss the use of organic polymer hosts for triplet-triplet annihilation upconversion for solar energy and many other applications. They explore the choice of host system (which often compromises contradicting factors such as high molecular mobility, low oxygen diffusion, and high material stability) and suggest future research directions (including homopolymer blends and copolymers, organic-inorganic hybrid hosts and controlling chromophore positioning).

This work was supported by the European Research Council.
