Polymers containing π-conjugated segments are a diverse group of large molecules with semiconducting and emissive properties, strong potential for use as active layers in Organic Light-Emitting Diodes (OLEDs). Stable blue-emitting materials, which utilized solution-processed OLED devices, essential their commercialization. Achieving balanced charge injection is challenging due to the wide bandgap between HOMO LUMO energy levels. This study examines optical photophysical characteristics...
In this study, fully aromatic polyether sulfones were developed, bearing blue, yellow, and orange-red π-conjugated semiconducting units. Carbazole-, anthracene-, benzothiadiazole-based fluorophores are copolymerized with a diphenylsulfone moiety. A diphenylpyridine comonomer was additionally utilized, acting as both solubilizing unit weak blue fluorescent group. Using rationale, polyarylethers high molecular weights, up to 70 kDa, showing film formation ability thermal stability, while...
Cotton cationization with low molecular-weight/polymeric cationic modifiers allows the effective dyeing of fabrics reactive dyes under salt-free and more environmentally-friendly conditions. The current work focuses on spectroscopic study intermolecular interactions, which dictate physicochemical process associated dyeing. Water-soluble copolymers vinyl benzyl chloride triethylammonium (VBCTEAM) have been used as cellulose modifiers. Dye uptake was assessed using Remazol Brilliant Blue...
In this study, novel copolymers consisting of blue and red chromophores are presented to induce emission tuning, enabling the definition white light in a single polymeric layer. These aromatic polyether sulfones exhibit high molecular weights, excellent solubility processability via solution deposition techniques. addition, by carefully controlling molar ratios composition, energy transfer mechanism, from chromophores, takes place us define properly covering entire range visible spectrum....
In this work, hybrid polymeric bis-tridentate iridium(III) complexes bearing derivatives of terpyridine (tpy) and 2,6-di(phenyl) pyridine as ligands were successfully synthesized evaluated red-light emitters. At first, the synthesis small molecular bis-tridendate Ir(III) alkoxy-, methyl-, or hydroxy-functionalized terpyridines a dihydroxyphenyl-pyridine moiety was accomplished. Molecular two polymerizable end-hydroxyl groups methyl- alkoxy-decorated copolymerized with...
Development of single-layer humidity-responsive membranes with mixed conductivity and potential applications across diverse fields.
A systematic study of the influence chemical substitution pattern semiconducting polymers carrying side chain perylene diimide (PDI) groups is presented. Semiconducting based on perflurophenyl quinoline (5FQ) were modified via a readily accessible nucleophilic reaction. The perfluorophenyl group was studied as an electron-withdrawing reactive functionality that can undergo fast aromatic substitution. PDI molecule, functionalized with one phenol bay area, used for fluorine atom at para...
A low-cost integrated ERT system based on serial bus and 2 evaluation boards with 8 electrodes is designed implemented. Tikhonov regularization adopted for image reconstruction conductance values measured from the system. Test results suggest that can produce reliable repeatable measurements reconstructions of multiple objects cost lower than 100 GBP. Comparisons between proposed commercial are also implemented to conclude advantages drawbacks
Extensive research has been dedicated to the solution-processable white organic light-emitting diodes (WOLEDs), which can potentially influence future solid-state lighting and full-color flat-panel displays. The proposed strategy based on WOLEDs involves blending two or more emitting polymers copolymerizing chromophores with different doping concentrations produce light emission from a single layer. Toward this direction, development of blends was conducted using commercial blue...
