Mechanistic Origin of Photodegradation and Impurity Effects in Donor–Acceptor Luminescent Radicals

Advanced Optical Materials, EarlyView.
Purification‐dependent impurities distort the apparent optical and analytical data of TTM‐based radicals without altering their intrinsic photophysical properties. Carbazole attachment elevates the activation barrier of the photodegradation pathway, offering design principles for achieving more robust luminescent radical materials.

Design and Utilization of Stable Hydrofluoroolefin‐Based Trifluoropropynyl Surrogate for Sonogashira Coupling

Advanced Synthesis &Catalysis, EarlyView.
A novel methodology for the construction of aromatic and heteroaromatic trifluoropropynyl derivatives has been developed. The new protocol is based on a tandem Sonogashira cross‐coupling reaction between a bench‐stable trifluoropropynyl carbinol reagent, generated from the commercially available and inexpensive hydrofluoroolefin‐1234yf gas, and (hetero)

Harnessing Carbenoid Reactivity From Imidazoles and Oxiranes

Advanced Synthesis &Catalysis, EarlyView.
The combination of azole compounds and oxiranes exhibits carbenoid reactivity at elevated temperatures, as demonstrated by the successful benzoin condensation of aromatic aldehydes. Using this catalytic system to polymerize bifunctional aldehyde/oxirane monomers yields thermosets with glass transition temperatures above 100°C.
