A novel blue emission PLED material: Synthesis, photophysical and electrochemical properties

Functional isocoumarin-containing polymers synthesized by rhodium-catalyzed oxidative polycoupling of aryl diacid and internal diyne

“…1 As a group of new advanced materials, polymers with fused-heterocyclic units in the main chains have attracted considerable attention. In the past few decades, a series of fused-heterocyclic polymers, for example, polymers containing benzodipyrrole, 2 benzofuran, 3 benzothiophene, 4 benzothiadiazole, 5 benzylcarb-azole, 6 and naphthopyran, 7 have been developed and investigated. Owing to their structural advantages of both the high conjugation of fused rings and the distinctive electrical and photophysical properties of heterocyclic moieties, they have found a variety of applications as external stimuli-responsive materials, 8 fluorescent sensors 9 and photoelectronic devices, such as polymer solar cells, 10 polymer field-effect transistors, 11 polymer light-emitting diodes, 6 etc.…”

Nicotinonitrile centered luminescent polymeric materials: Structural, optical, electrochemical, and theoretical investigations

“…merits over their inorganic competitors. [9][10] They work on the principle of electroluminescence, that is, injection of charge in a semiconducting material under an electric field, subsequently the radiative recombination of these charges. [11] In fact, these devices have great prospects in their applications, provided they show significant improvement in performance and device stability.…”

“…[ 6‐8 ] Among them, currently, the PLEDs are a rapidly progressing technology owing to their utility in energy‐saving solid‐state lighting and flat‐panel full‐color displays with many merits over their inorganic competitors. [ 9‐10 ] They work on the principle of electroluminescence, that is, injection of charge in a semiconducting material under an electric field, subsequently the radiative recombination of these charges. [ 11 ] In fact, these devices have great prospects in their applications, provided they show significant improvement in performance and device stability.…”

New cyanopyridine‐based π‐conjugative poly(azomethine)s: Synthesis, characterization and electroluminescence studies

“…[1][2][3][4][5] The OLEDs are a rapidly progressing technology with ample benefits over their inorganic counterparts due to their possible applications in solid-state lighting and full-color flat-panel displays. [6][7][8] Right now, the benchmark performance has been achieved to red and green light-emitting materials, while there is a necessity to investigate the LED material which emits in the blue-violet region of the spectrum. 2,9,10 Active research in this area has gained substantial attention for developing suitable organic materials to meet the standards Commission International del'E'clairage coordinate of CIEy<0.08 setup by National Television System Committee, but attaining high external quantum efficiencies still continued to be a main challenge.…”
