Chemistry – A European Journal, EarlyView.A molecular design strategy combines lignin‐derived aromatic units, sugar‐derived furan groups, and flexible glycol segments to create wet‐spinnable polyurethanes. Thermally reversible Diels–Alder crosslinking chemistry enables formation of crosslinked thermosetting fibers, repeated de‐crosslinking/re‐crosslinking cycles, and tunable fiber properties ...

La superficie SI(100)-2x1 como dienófilo en una reacción tipo DIELS-ALDER
Revista de Química, 1999 Se estudió la adsorción de 1,3-butadieno y de 2,3-dimetil-1,3-butadieno sobre una superficie monocristalina de Si(100)-2x1 bajo condiciones de máximo vacío (ultra-high vacuum, UHV) observándose que, a temperatura ambiente, cada dieno reacciona mediante ...

Self‐Immolative Poly(Benzyl Ether)s: Design Principles and Controlled Depolymerization
Chemistry – A European Journal, EarlyView.Unzipping to Sustainability: This Concept article explores the thermodynamic design of quinone‐methide (QM)‐based poly(benzyl ether)s (PBEs). It explains how a low ceiling temperature (Tc), QM stability, and an entropic gain drive rapid depolymerization (“unzipping”) of PBEs into monomers.

European Journal of Organic Chemistry, EarlyView.More than a century after Albrecht's original proposal, an unexpected synthetic relationship between the historically misassigned Michael adduct type and the genuine Diels–Alder product is revealed. Experimental and theoretical studies show that the Michael adduct is not formed directly from the diene and dienophile, but instead arises through ...
