By investigating the effects of electron donor topology and the hetero[6]radialene structure on the 3D COF photocatalytic activity, a twisted BF structure was found to improve organic pollutant degradation and water hydrogen production.
Hole-transporting material (HTM) plays an important role in PSCs. We report a novel and low-cost, bifluorenylidene-based HTM, denoted as sp-35, which achieved a high PCE of 21.59% and demonstrated good long-term stability compared to spiro-OMeTAD.
Fully sp2-carbon connected polymeric frameworks with conformationally tuned flexibilities, rich redox sites, and porous structures, were constructed, and fabricated with carbon nanotubes to film-like electrodes for high-performance electrochemical lithium-ion storage.
Semiconducting sp/sp2-carbon polymeric frameworks are derived from the key segments of fullerene and graphyne for promising visible-light photocatalysis.
The twisted conformer-predominant diphenoquinones fused with thiophene rings exhibited deep LUMO energy levels and apparent n-type semiconductor properties.
