Modulating the Optoelectronic Properties of Tripodal Fluorophores Through Fluorine‐Substituted Peripheral Phenyls

Chemistry – A European Journal, EarlyView.
C3‐symmetric D‐(π‐D‐π‐A)3 fluorophores featuring central triphenylamine donor, polarizable 2,5‐divinylthiophene linker, and a broad portfolio of fluorine‐based substituents show tunable (non)linear optical properties. ABSTRACT Fourteen novel tripodal fluorophores based on a central triphenylamine donor, electron‐rich, and polarizable divinylthiophene ...

On the Vapor Pressures, Phase Transitions, and Solid‐State Fluorescence of 2‐(2‐Hydroxyphenyl)benzoxazole and 2‐(2‐Hydroxyphenyl)benzothiazole

ChemPhysChem, EarlyView.
Benzazoles 2‐(2‐hydroxyphenyl)benzothiazole and 2‐(2‐hydroxyphenyl)benzoxazole exhibit tunable optoelectronic properties via excited‐state intramolecular proton transfer. Combining thermogravimetry (TG‐DSC), vapor pressure measurements, and fluorescence spectroscopy, how sulfur (S) versus oxygen (O) substitution dictates their stability, sublimation ...

Kampen om OL-ringene - eller OL-ringvirkningene?

, 2017
I november 2011 vedtok idrettsstyret i Norges idrettsforbund og olympiske og paralympiske komité å gå inn for at Oslo skulle søke om de olympiske og paralympiske vinterleker i 2022. For å kartlegge oppslutningen i Oslos befolkning ble det bestemt at det skulle avholdes en rådgivende folkeavstemning i Oslo kommune parallelt med stortingsvalget i ...
