Inside Front Cover: Solution-processed D-A-π-A-D radicals for highly efficient photothermal conversion

Abstract

Stable aromatic nitric acid radicals with open-shell singlet ground state and thermally excited triplet state were readily prepared and achieved ultra-wide absorption spectra in powders. These radical materials efficiently suppress radiation transitions and exhibit outstanding photothermal conversion performance, providing a rational design approach for solar-driven interfacial water evaporation active materials (e426).
