Enhanced Stability of Perovskite Solar Cells Incorporating Dopant-Free Crystalline Spiro-OMeTAD Layers by Vacuum Sublimation
(Wiley-Blackwell, 2020)
The main handicap still hindering the eventual exploitation of organometal halide perovskite-based solar cells is their poor stability under prolonged illumination, ambient conditions, and increased temperatures. This ...

Zwitterionic amidinates as effective ligands for platinum nanoparticle hydrogenation catalysts
(Royal Society of Chemistry, 2017)
Ligand control of metal nanoparticles (MNPs) is rapidly gaining importance as ligands can stabilize the MNPs and regulate their catalytic properties. Herein we report the first example of Pt NPs ligated by imidazoliumamidinate ...

AuI-Catalyzed Hydroalkynylation of Haloalkynes
(American Chemical Society, 2020)
The AuI-catalyzed reaction between terminal alkynes and aromatic haloalkynes proceeds through divergent pathways depending on the nature of the catalyst counteranion. Thus, cationic complexes containing strongly basic NHC ...
