A ring expansion strategy towards diverse azaheterocycles
Ring expansion to “grow” larger N-heterocycles often uses cycloaddition of strained aza-rings with π-bonds. Here, we report a formal cross-dimerization between three-membered aza-heterocycles and 3- and 4-membered-ring ketones, providing a straightforward means of assembling diverse N-heterocycles.
The Effect of Water on Colloidal Quantum Dot Solar Cells
We reveal that ambient water plays an essential role in surface hydroxylation, epitaxial QDs fusion, and trap behavior in QD photovoltaics. By manipulating the deposition techniques and film morphology, the side effect of ambient water on CQD solar cells can be effectively suppressed.
