Nickel complexes of phosphine-appended benzannulated boron heterocycles [PDF]

open access: yes, 2019
We report the synthesis and characterization of two diphosphine nickel complexes containing 9-borafluorene (PBFlu, 9-(diisopropylphosphino)phenyl-9-borafluorene) and 9,10-dihydroboranthrene (B 2 P 2 , 9,10-bis(2-(diisopropylphosphino)phenyl)-9,10 ...

Interplay of Backbone Conformation, Morphology and Thermoelectric Properties of Benzodifuranone‐Isatin Acceptor Polymers

open access: yesAdvanced Electronic Materials, EarlyView.
Modification of polymer backbone via halogenation and comonomer selection leads to conjugated backbones of different stereoelectronic properties, thin film morphologies, and electrical characteristics. The interplay of conformational isomerism, coplanarity, backbone curvature, backbone orientation, and ordering in thin films, electrical conductivity ...

Acid‐ and Nucleophile‐Gated Photoisomerization of Phosphaindirubin

open access: yesAngewandte Chemie, EarlyView.
Triply gated isomerization: In polar solvents, a phosphorus‐containing indirubin photoswitch undergoes visible‐light‐driven Z→E isomerization only when protonated, and reverts thermally via nucleophile‐catalyzed back‐isomerization. This three‐way control by light, acid, and nucleophile enables reversible photoisomerization.

Low‐Carbon Poly(3‐vinyl‐N‐methylphenothiazine) Electrode Formulation Using PEDOT:PSS (poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate)) for Lithium‐Based Energy Storage

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Organic electrode materials typically suffer from low electronic conductivity, requiring large amounts of carbon additives. Herein, a conducting polymer, PEDOT:PSS, is introduced as a partial replacement for carbon black, reducing the carbon content to 15 wt%.

Synthesis and Characterization of Unusual S=1 Fe(0)‐Silyl Complexes Supported by Styrene Ligands

open access: yesAngewandte Chemie, EarlyView.
Despite the long‐standing importance of iron‐silicon bonds as related to catalysis, high‐spin Fe(0)‐silyl complexes remain a historical synthetic challenge in the field. Herein, we report the first series of high‐spin S = 1, styrene‐stabilized Fe(0)‐silyl complexes followed by extensive characterization via Mössbauer spectroscopy, single crystal X‐ray ...

Development and systematic evaluation of triamine‐based functional deep eutectic solvents for efficient CO2 capture

open access: yesAIChE Journal, EarlyView.
Abstract The development of advanced absorbents for effectively capturing carbon dioxide is crucial in mitigating greenhouse gas emissions. This study introduced a series of deep eutectic solvents (DESs) for CO2 capture and identified the most promising DESs with the stepwise screening method based on their absorption capacity, absorption rate, thermal
