Substituent‐Controlled Energetics and Barriers of Mechanochromic Spiropyran‐Functionalized Poly(ɛ‐caprolactone)

open access: yesMacromolecular Chemistry and Physics, Volume 224, Issue 1, January 2023., 2023
Four different spiropyrans with consistently varying substitution patterns are incorporated into the middle of poly(ε‐caprolactone) used for tensile testing with in‐situ UV–vis spectroscopy. The influence of combined electronic and steric effects on the force‐induced spiropyran–merocyanine transition is investigated theoretically and experimentally by ...

Infrared Irradiation‐Assisted Green Approach for Pd‐Catalyzed Buchwald–Hartwig Amination

open access: yesChemistry – A European Journal, EarlyView.
For the first time, infrared (IR) irradiation is demonstrated as an effective energy source, able to assist the Pd‐catalyzed Buchwald–Hartwig amination. The C–N coupling reactions were performed under quasi‐solvent‐free conditions, in nonanhydrous conditions and without the exclusion of air, using aryl iodides and bromides functionalized with both ...
