On the Planarity of Heterocyclic Bay‐Substituted Perylenediimides: Insight into the Fluorescent Photoinduced Electron Transfer Sensing Framework

European Journal of Organic Chemistry, EarlyView.
Near‐infrared fluorescent pH indicators based on perylenediimide were constructed in a modular receptor–spacer–fluorophore–spacer–receptor format with heterocyclic amino moieties at the bay positions. Counterintuitively, the dibrominated intermediate with two heavy atoms is more emissive than the heterocyclic compounds.

Well‐Defined Anilido–Imine Iron(II) Complexes for Catalytic Intramolecular Alkene Hydroamination of Primary Amines

European Journal of Organic Chemistry, EarlyView.
We synthesize and characterize a series of well‐defined anilido–imine Fe(II) alkyl complexes that demonstrate high activity and selectivity in the cyclohydroamination of unprotected primary amines tethered to unactivated alkenes. By tuning the steric and electronic parameters of the anilido–imine ligand, we develop a catalyst that outperforms ...

Mesityl‐Substituted Azuleno[1′,2′:4,5]pyrrolo[2,3‐b]quinoxalines: Synthesis, Functionalization, Photophysical, and Electrochemical Properties

European Journal of Organic Chemistry, EarlyView.
Azuleno[1′,2′:4,5]pyrrolo[2,3‐b]quinoxaline with a mesityl group as a solubilizing group was synthesized. By synthesizing derivatives in which various functional groups were introduced into two electronically distinct sites, the pyrrole nitrogen atom and the azulene five‐membered ring, we were able to reveal that the photophysical and electrochemical ...

CEEN: A Control Software for Coupled Electrochemistry, EPR, and NMR for Redox Flow Battery and Electrosynthesis Research

Magnetic Resonance in Chemistry, EarlyView.
We present CEEN: a Python‐based control software for coupled electrochemistry, EPR, and NMR for redox flow battery (RFB) and electrosynthesis research. We demonstrate CEEN through practical applications relevant to aqueous organic and inorganic RFB and electrochemical synthesis research. The same setup can be readily used to study any (electrochemical)

Development of NMP‐001, A Nitromethane‐Based Green Propellant

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT This paper discusses the development of a model monopropellant that is aimed at exploring the applicability of nitromethane‐based propellants as an alternative to hydrazine. This approach addresses the challenges faced by HAN‐, ADN‐based propulsion by being more cost‐effective while providing similar performance figures.

University teaching of mass spectrometry as a key practical technique within the context of a fully integrated, spiral curriculum

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Mass spectrometry (MS) is introduced to high school students in the UK in many pre‐university course syllabi. As such, we have identified the use of MS as a key technique that should be taught practically to undergraduates from the outset of their studies.
