We present new imaging data on the ultracompact H ii region G45.45+0.06 at nearand mid-infrared wavelengths. High-resolution data were taken in the H and K ′ bands using ESO’s adaptive optics system ADONIS. The resulting images with a generic resolution of 0. ′′4 for the first time allow the resolution of the object into several single point-like sources. Additionally, we present images obtaine...

Organic-inorganic hybrid heterojunctions have potential as the basis for future photovoltaic devices. Herein, we report the results of investigations exploring the possibility of using pentacene and tetracene as photoelectron donors in conjunction with PbS nanocrystals (PbS-NCs). Photoinduced charge transfer was probed using external quantum efficiency measurements on acene:PbS-NC hybrid photov...

Enantioenriched secondary allylic carbamates have been deprotonated with sBuLi and reacted with boronic esters. In contrast to other electrophiles, high α-selectivity was observed and the boronate complexes were formed with almost complete retention of stereochemistry. The boronate complexes underwent a stereospecific 1,2-migration leading to tertiary allylic boronic esters with high er (>98:2)...
