Photochemistry of N‐Phenyl Benzonaphthothiophene and Dinaphthothiophene Sulfoximines

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The sequential photorelease of nitrenes and atomic oxygen [O(3P)] from N‑phenyl benzonaphthothiophene and dinaphthothiophene sulfoximines is a rare photochemical phenomenon in which two reactive intermediates can be released from a single chromophore. The sequential photorelease of nitrenes and atomic oxygen [O(3P)] is a rare photochemical phenomenon ...

Activating Triplet Excitons in COFs via Layer-Bridging Co Single Atoms for Photocatalytic H<sub>2</sub>O<sub>2</sub> Production and Tandem C─N Coupling. [PDF]

open access: yesAngew Chem Int Ed Engl
This work demonstrates a layer‐bridging coordination strategy of Co single atoms in COFs that promotes the formation and utilization of triplet excited states. The introduction of Co single atoms induces pronounced energy‐level splitting and enhanced spin–orbit coupling, facilitating the generation of 1O2 and O2•– for efficient photocatalytic H2O2 ...

Zero‐Dimensional Organic–Inorganic Hybrid Metal Halides as Luminescent Materials: A Review From the Perspective of Molecular Level

open access: yesLaser &Photonics Reviews, EarlyView.
Advances in zero‐dimensional organic–inorganic hybrid metal halides are reviewed from a molecular‐engineering perspective. Four design strategies (polyhedral‐architecture, elemental‐composition‐substitution, donor–acceptor/host–guest, multi‐emissive‐center integration‐coupling engineering) and structure‐performance trade‐offs are summarized.

Conjugation‐Length Dependent Interplay Between Charge Transfer and Locally Excited States in Sequence‐Defined Donor–Acceptor Substituted Oligo(Phenylene Ethynylene)s

open access: yesMacromolecular Rapid Communications, EarlyView.
Iterative synthesis gives access to sequence‐defined oligo(para‐phenylene ethynylene)s, bridging donor and acceptor units through stepwise extension of the conjugated backbone. Accurate length control enables systematic structure‐property relationship investigations across absorption, emission, and excited‐state dynamics.

Resorufin‐Catalyzed PhotoATRP Under Red Light

open access: yesMacromolecular Rapid Communications, EarlyView.
The sodium salt of resorufin, a commercially available, water‐soluble dye, serves as an efficient photocatalyst for dual‐catalysis PhotoATRP under red light. High control is achieved at catalyst loadings as low as 1 ppm. This versatile system operates across the visible spectrum in both organic and aqueous media, relying on a dynamic oxidative ...
