Removal of Surface Oxygen Vacancies Increases Conductance Through TiO<sub>2</sub> Thin Films for Perovskite Solar Cells Open
We report that UV-ozone treatment of TiO2 anatase thin films is an efficient method to increase the conductance through the film by more than 2 orders of magnitude. The increase in conductance is quantified via conductive scanning force mi…

A Conjugated Microporous Polymer for Palladium‐Free, Visible Light‐Promoted Photocatalytic Stille‐Type Coupling Reactions Open
The Stille coupling reaction is a versatile method to mainly form aromatic CC bonds. However, up to now, the use of palladium catalysts is necessary. Here, a palladium‐free and photocatalytic Stille‐type coupling reaction of aryl iodides …
