https://t.co/x2UzD5AfbH It turns out you dont need a heterojunction to generate charges in organic materials. Additionally the generated CT state is spin-paired. I think this is the future of OPV. Thanks @NatureMaterials

Thanks @_iainmcculloch. Dont work yourself too hard in San Diego
Fantastic paper from @bronsteingroup precisely controlling the spacial distance between donor and acceptor units on polymers and the effect on charge transfer states. Well worth a read.

exciton-phonon coupling study led by @RaoGroupCAM and @PratyushG_UCam. Thanks for including us!
Thrilled to announce my main PhD research is out in @Nature. We discovered how, by tweaking exciton wavefunctions & vibrational localization, we can decouple exciton-phonon coupling in organic molecules at high frequencies. https://t.co/hQDz8IJ4Qd
