Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Wang, Baowen, once mentioned the application of 6298-19-7, Name is 2-Chloropyridin-3-amine, molecular formula is C5H5ClN2, molecular weight is 128.5596, MDL number is MFCD00006238, category is pyridine-derivatives. Now introduce a scientific discovery about this category, Application In Synthesis of 2-Chloropyridin-3-amine.
Efficient all-solution-processed near-infrared (NIR) polymer light-emitting diode (PLED) based on the [Ir((CN1)-N-boolean AND)(2)((CN2)-N-boolean AND)]-heteroleptic Ir(III)-complex [Ir(iqbt)(2)(Br-ppy)]
Despite the potential candidates of NIR emissive cyclometalated Ir(III)-complexes for large-area and scalable NIR-PLEDs, the realization of their all-solution-processed devices with low cost and without sacrifice of satisfactory performance, is much challenging. In this work, using Hiqbt (1-(benzo[b]-thiophen-2-yl)-isoquinoline) as the C boolean AND N-1 main ligand and Br-Hppy (2-(4-bromophenyl)pyridine) as the C boolean AND N-2 ancillary ligand, the [Ir (C boolean AND N-1)(2)(C boolean AND N-2)]-heteroleptic complex [Ir(iqbt)(2)(Br-ppy)] with efficient NIR-phosphorescence (lambda(em) = 692 nm; 69% of the lambda(em) >= 700 nm proportion; iota = 0.48 mu s and Phi(PL) = 0.19) was molecularly designed. Meanwhile, through the doping of the Ir(III)-complex [Ir(iqbt)(2)(Br-ppy)], its TmPyPB-assisted (TmPyPB = (1,3,5-tri[(3-pyridyl)phen-3-yl]-benzene) multi-layer NIR-PLED-I and all-solution-processed NIR-PLED-II were realized, respectively. Saliently, the attractive performance (eta(Max)(EQE) = 3.20% and negligible (ca. 5%) efficiency roll-off) of the NIR-PLED-II, renders [Ir(C boolean AND N-1)(2)(C boolean AND N-2)]-heteroleptic Ir(III)-complexes a new platform to all-solution-processed NIR-PLEDs.
