Donor Extended Blue TADF Dendrimer for High‐Performance Solution‐Processed OLEDs

Advanced Science, EarlyView.
A dendronized MR‐TADF emitter, DOBNA‐SpAc‐DCz, was designed to improve solubility, hole transport, and exciton dynamics for solution‐processed OLEDs. Incorporation of ter(tert‐butylcarbazole) dendrons decreases ΔEST and accelerates RISC, yielding short delayed lifetimes (∼2 µs).

Sterisch überfrachtete Alken‐Photo‐Redox‐Schalter auf Basis von Chinolinium/Carben Bausteinen

Angewandte Chemie, EarlyView.
Eine modulare Synthese einer neuen Klasse von Photo‐ und Redox‐Schaltern wird beschrieben, die auf der Kombination von Chinoliniumsalzen und Carbenen basiert. Das photochemische Schalten ermöglicht einen selektiven Wechsel zwischen gefalteten E/Z‐Isomeren, während das elektrochemische Schalten den Wechsel zwischen neutralen, radikalkationischen und ...

Overcrowded Alkene Photo‐Redox‐Switches Based on Quinolinium/Carbene Building Blocks

Angewandte Chemie International Edition, EarlyView.
A modular synthesis of a new class of photo‐ and redox‐switches is described based on the combination of quinolinium salts and carbenes. Photochemical switching allows to selectively switch between folded E/Z isomers, while electrochemical switching allows to change between neutral, radical cation and dicationic oxidation states, which are all isolable

Catalytic Pyrolysis of Waste Polystyrene Over Fe–B Composite Catalyst for Enhanced Liquid Fuel Production

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Healthcare derived polystyrene waste represents a growing and under addressed fraction of plastic waste streams due to contamination risks and limited recyclability. This study aims to investigate the valorization of waste polystyrene foam through catalytic and noncatalytic pyrolysis pathways to evaluate product yield distribution and identify

A facile and efficient synthesis of 1,8-dioxodecahydroacridines derivatives catalyzed by cobalt–alanine metal complex under aqueous ethanol media

BMC Chemistry, 2019
A facile and convenient method for the synthesis of acridines and its derivatives was developed through one-pot, three-component condensation reaction of aromatic aldehydes, 5,5-dimethyl-1,3-cyclohexanedione, aryl amines or ammonium acetates in the ...

The interactions of monomeric acridines and unsymmetrical bisacridines (UAs) with DNA duplexes: an insight provided by NMR and MD studies

Scientific Reports, 2023
Members of a novel class of anticancer compounds, exhibiting high antitumor activity, i.e. the unsymmetrical bisacridines (UAs), consist of two heteroaromatic ring systems.

Magnetoelastic Cell Monitoring System for Evaluating the Effects of Surface Chemistry on the Performance of Mesenchymal Stem Cell Growth

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The recent clinical adoption of cell therapies has increased the need for more efficient, robust, and reproducible manufacturing technologies. Human mesenchymal stromal cells (hMSCs), a major component of the cell and immunotherapeutic market, remain challenging to manufacture at scale because they require surface attachment and are highly ...

Single‐Step Synthesis of Dithieno[3,2‐b:2′,3′‐e]Pyridines and Their Acid‐Dependent Optical and Photosensitising Properties

Chemistry – A European Journal, EarlyView.
The synthesis of dithieno[3,2‐b:2′,3′‐e]pyridines (DTPs) is herein reported, and their optical properties are studied both experimentally and computationally. Protonation or methylation of the nitrogen atom induced bathochromic shifts in their absorption and emission spectra.

Synthesis, DNA-Binding and Antiproliferative Properties of Acridine and 5-Methylacridine Derivatives

Molecules, 2012
Several acridine derivatives were synthesized and their anti-proliferative activity was determined. The most active molecules were derivatives of 5-methylacridine-4-carboxylic acid. The DNA binding properties of the synthesized acridines were analyzed by
