Iron‐Photocatalyzed C(sp3)–H Phosphonylation of Alkanes

Angewandte Chemie, EarlyView.
Alkyl phosphonates are valuable motifs that can be prepared by phosphonylations of various common functional groups. However, direct phosphonylations of C(sp3)–H bonds are limited to activated positions. Herein, we report an iron‐photocatalyzed phosphonylation of unactivated C(sp3)–H bonds using a novel phosphite radical trap, which is equipped with an

Cage‐Type Porous Organic Salts as Ship‐in‐a‐Bottle Nanoreactors for Light‐Transparent and Reusable Molecular Photocatalysts

Angewandte Chemie, EarlyView.
Light‐transparent, cage‐type porous organic salts (POSs) function as nanoreactors that heterogenize molecularly defined photocatalysts through size exclusion. Photocatalysts are encapsulated intact during crystallization, providing confined yet accessible reaction fields under visible light without catalyst modification.

Quantitative Photo‐Reforming of Biomass to CO Spurred by In Situ Protonation of Carbon Dioxide Radical Anions

Angewandte Chemie, EarlyView.
A “two‐in‐one” photoreduction strategy enabled by electron‐rich yolk Cd species both remote from and adjacent to sulfur vacancies is delivered to be ultraselective for the reduction of O2 and •CO2− in situ formed on the shell Bi2S3 composition (hole) by water oxidation and oxidative C–C cleavage of various biomass organic acids, furnishing CO with > 99%

Gold(III) Semiquinone Complexes: Synthesis, Structure, and Application in Photocatalysis

Angewandte Chemie, EarlyView.
Au(III) catecholate complexes engage into electron donor acceptor (EDA) interactions with aryldiazonium salts, enabling single‐electron transfer under green light irradiation. Ligand‐centered one‐electron oxidation to stable semi‐quinone complexes provides a new platform for standalone Au(III) photoredox catalysis, as substantiated by the C–H arylation

Phosphoryl Radicals from Trivalent Iminyl Phosphines: A Photocatalytic Approach to N‐Phosphoryl Azetidines

Angewandte Chemie, EarlyView.
Photochemically generated phosphoryl radicals from iminyl phosphines enable strain‐release addition to azabicyclobutanes, providing access to elusive N‐phosphoryl azetidines. Combined experimental, computational, and EPR studies reveal an unconventional water‐assisted photoredox pathway.

Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

Angewandte Chemie, EarlyView.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...
