Kinetics of photoinduced ordering in azo-dye films: two-state and diffusion models

, 2008
We study the kinetics of photoinduced ordering in the azo-dye SD1 photoaligning layers and present the results of modeling performed using two different phenomenological approaches.

National Environmental Policies and Corporate Green Innovation: The Mirroring Versus Substitution Hypotheses

Business Strategy and the Environment, EarlyView.
ABSTRACT Drawing on comparative institutional theory, we study the nature and magnitude of the effects of national environmental policies on corporate green innovation in developed versus emerging markets. Using a sample of 1831 listed firms in 34 countries from 2002 to 2020, we find that national environmental policies increase corporate green ...

The Stabilization of High‐Nitrogen Systems: 10 Catenated Nitrogen Chain

Chemistry – A European Journal, EarlyView.
Improving the understanding of high‐nitrogen materials. ABSTRACT High‐nitrogen materials have attracted intense interest in recent decades due to their unique chemical, physical, and biological properties. Stabilizing high‐nitrogen materials is often challenging as they become more unstable with increasing nitrogen catenation and nitrogen mass ...

Synthesis and Characterization of Carbazole‐Containing Aza[7]helicenes

Chemistry – A European Journal, EarlyView.
Double ortho fusion led to different aza[7]helicene frameworks showing strong acidochromic behavior, singlet excited energies being more than twice the triplet energy, and high racemization barriers, allowing chiral resolution and ECD measurements. ABSTRACT Azahelicenes have attracted significant interest due to their intrinsic axial chirality and ...

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 ...

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.
