Regioselective Diversification of Aminopyrazoles via Ir‐Catalyzed C─H Borylation

Advanced Synthesis &Catalysis, Volume 368, Issue 21, 3 November 2026.
Aminopyrazoles, an important bioactive pharmacophore, are typically accessed inefficiently through de novo syntheses that yield isomeric mixtures of 3‐ and 5‐substituted derivatives. To address this challenge, we have elaborated readily available 3‐ and 5‐aminopyrazole fragments using Ir C─H borylation, regioselectively furnishing boronates for ...

Dual‐Mode Electrophoretic Displays Enabled by Quantum Dot‐Decorated PR48:2 Pigment Particles and TiO2 for All‐Weather Visibility, Excellent Bistability, and Enhanced Readability

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
This study presents a novel quantum dot electrophoretic display (QDEPD), which combines electro‐controlled reflection and optically‐triggered emission to achieve efficient multi‐modal switching within a single pixel. By incorporating multi‐component nanostructures, the system enhances functional integration and multi‐modal response capabilities.

Position-addressable nano-scaffolds. II. The introduction of one, two, or three addressable succinimide linkage points onto the under-surface of 'southern' cavity bis-porphyins

, 2003
Cavity bis-porphyins containing up to three addressable succinimide rings on the underface are reported for the first time. This is achieved by site-selective addition of o-chloranil to the 7-oxanorbornene TT-bond of O-bridged ...

Emergent Atropisomerism Through Diels–Alder Reactions of Vinylallenes

European Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.
Cycloaddition‐induced geometric reorganization transforms achiral vinylallenes into atropisomeric styrenes. Conformational flexibility governs atropisomerization barriers, thermodynamic preferences, and configurational stability. Atropisomeric styrenes remain comparatively underdeveloped because configurational stability about the C(sp2)C(sp2) bond is
