In a document, author is Xue, Jie.

Despite the great potential for applications spanning, from military night-vision displays and information-secured devices to civilian medical diagnostics and phototherapy, the development of highly efficient, stable, and low-cost near-infrared (NIR) emitting lumophores is still a formidable challenge. Herein, we report two novel NIR-emitting homoleptic facial Ir(III) complexes based on extended pi-conjugated benzo[g]phthalazine ligands, namely, tris[1,4-di(thiophen-2-yl)benzo(g]phthalazine] (Ir(dtbpa)(3), 1) and tris[1-(2,4-bis(trifluoromethyl)pheny1)-4-(thiophen-2-y1)-benzo[g]phthalazine] iridium(III) (Ir(Ftbpa)(3), 2). Actually, these two ligarids not only enable simple one-pot synthesis of homoleptic Ir(III) complexes without any catalyst under mild conditions, but also contribute to intense NIR-emission with high photoluminescence quantum yield up to 5.2% at 824 nm for 1 and 17.3% at 765 nm for 2 respectively. Single-crystal structure of 1 demonstrates desired facial form with short Ir-N and Ir-C bonds because of strong coordination and small steric hindrance of those highly conjugated C<^>N=N ligands. Importantly, the incorporation Of CF3 groups in 2 further leads to high thermal stability and a good ability to sublime, thus resulting in ultrapurity for highly efficient NIR-organic light-emitting diodes (NIR-OLEDs) with a high maximum external quantum efficiency of 4.5% at 760 run and small efficiency roll-off remaining of 3.5% at 100 mA. cm(-2), values which rank with those of the most efficient NIR-OLEDs with small roll-off and peak emission over 750 nm. Notably, the content percentages of the noble metal in these two complexes, (similar to 10% Ir) are markedly lower by about two-thirds than that of typical green-emitting tris(2-phenylpyridine)iridium (similar to 30% Ir). The findings may provide a new strategy to develop robust NIR emitters and achieve high efficiency, small roll-off, and low cost simultaneously in NIR-OLEDs for practical applications.

With the volume and accessibility of scientific research increasing across the world, it has never been more important to continue building the reputation for quality and ethical publishing we’ve spent the past two centuries establishing. 886-86-2, Name is Ethyl 3-aminobenzoate methanesulfonate, SMILES is O=C(OCC)C1=CC=CC(N)=C1.CS(=O)(O)=O, in an article , author is Zinczenko, Wiktoria, once mentioned of 886-86-2, Quality Control of Ethyl 3-aminobenzoate methanesulfonate.

Triazolo[3,4-a]phthalazine as well as their chloro and nitro derivatives were subjected to the reactions with the carbanions typical for the vicarious nucleophilic substitution (VNS) of hydrogen. The reactions were strongly dependent on the substituents present on the triazolo[3,4-a]phthalazine ring and resulted not only in the substitution of hydrogen but also in exchange of chlorine atom and pyridazine ring scission; the latter process dominated for the unsubstituted triazolophthalazine. Two of the products showed promising stimulating activity towards the central nervous system with no significant toxic effects.
