Decoding Synergistic Pathways in Bimetallic MOFs for Advanced Oxidation Processes

Advanced Materials, EarlyView.
This review presents a unified framework linking metal pairing and framework design with electronic structure, redox cycling, oxidant activation, reactive‐species generation, and catalytic performance across photocatalytic and oxidant‐based BMOF‐AOPs. The resulting design principles guide the development of hydrolytically stable and efficient BMOFs for

Reactivity‐Guided Janus Graphene With Asymmetric Interfacial Electrostatics for Tunable Charge Transport

Advanced Materials, EarlyView.
Stepwise dual‐side functionalization creates covalent Janus graphene with chemically and electrostatically asymmetric interfaces. The resulting nonadditive surface‐potential response and pronounced charge‐transport modulation demonstrate a versatile route for tailoring the electronic properties of graphene.

Substituent-Dependent Negative Hyperconjugation in 2-Aryl-1,3-N,N-heterocycles. Fine-Tuned Anomeric Effect?

, 2016
The epimerization reactions of conformationally inflexible 2-aryl-1,3-N,N-heterocycles were used as model systems to study the role of the nitrogen lone pair-C2 associated antibonding orbital hyperconjugative interactions in the experimentally observed ...

Substituent Effects in Ugi–Smiles Reactions

The Journal of Physical Chemistry A, 2013
In a recent communication, we described the mechanism of the well-known Ugi-type reactions with a model system (J. Org. Chem. 2012, 77, 1361-1366). Herein, focusing on the Ugi-Smiles coupling, we study the effects of each of the four reactants on the energy profile to further explain the experimental results.

Intramolecular Direct Arylation Enables Access to Diverse Photophysical Properties for π‐Expanded 1,4‐Dihydropyrrolo[3,2‐b]pyrroles

Advanced Optical Materials, EarlyView.
The unique combination of photophysical properties for π‐expanded 1,4‐dihydropyrrolo[3,2‐b]pyrroles (DHPPs) can be reached via a new synthetic approach. π‐Expanded DHPPs possessing electron‐withdrawing functionalities with emission reaching 700 nm, as well as large double helical systems were prepared and investigated.

Dual Substituent Parameter Modeling of Theoretical, NMR and IR Spectral Data of 5-Substituted Indole-2,3-diones

Molecules, 2002
Correlations of AM1 and PM3 theoretical data, 13C-NMR substituent chemical shifts (13C-SCS) and IR carbonyl group wave numbers [ν(C3═O)] were studied using dual substituent parameter (DSP) models for 5-substituted indole-2,3-diones.
