Porphyrin‐Geländer–Helical Conjugated Banister Type Porphyrin Dyads

Chemistry – A European Journal, EarlyView.
Porphyrin arrays go chiral–A porphyrin Geländer macrocycle represents the intriguing prototype architecture of helically chiral butadiyne‐linked porphyrin arrays. This study combines synthetic, spectroscopic, and computational methods to shed light on its structure, chiroptical properties, and tunability, highlighting its promise for advancing ...

β‐Scission of Tertiary Alcohols on a Platinum‐Loaded Titanium Dioxide Photocatalyst for C─C Bond‐Forming Reactions

Chemistry – A European Journal, EarlyView.
A strategy for the Pt/TiO2‐photocatalyzed β‐scission of nonactivated 3° alcohols in the absence of external oxidants and additives was developed. A wide variety of C‐centered radicals were generated and subsequently engaged in C─C bond‐forming reactions.

Mimicking The Photosynthetic Special Pair With Aluminum(III) Porphyrin Homodimer – Fullerene (C60) Supramolecular Assemblies Capable of Long‐Lived Charge Separation

Chemistry – A European Journal, EarlyView.
The axial‐bonding of aluminum(III) porphyrins was used to create two covalently linked special‐pair mimics to probe charge‐transfer between a porphyrin dimer and a C60 unit for artificial photosynthesis. Although excitonic coupling between the porphyrins is weak, incorporation of a second porphyrin markedly increases both the yield and lifetime of the ...

On the Reaction Mechanism of Nitrate Radical and DMPO in Non‐aqueous Photocatalytic Media

Chemistry – A European Journal, EarlyView.
This work identifies 2‐oxo‐5,5‐dimethyl‐1‐pyrroline 1‐oxyl (DMPOX), formed via the selective oxidation of 5,5‐dimethyl‐1‐pyrroline N‐oxide (DMPO) by nitrate radicals (NO3•) in nonaqueous media, as a distinctive EPR fingerprint of NO3•. The DFT‐supported mechanism clarifies its formation pathway and highlights DMPOX detection as a robust tool for ...

Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

Chemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.
