Durene-decorated CBP derivatives as phosphorescent hosts and exciton-blocking materials for efficient blue OLEDs was written by Deng, Lijun;Wang, Xinzeng;Zhang, Zhengchuan;Li, Jiuyan. And the article was included in Journal of Materials Chemistry in 2012.HPLC of Formula: 3268-21-1 This article mentions the following:

Two novel durene-containing mols., 1,4-bis[4-(9-carbazolyl)phenyl]durene (CPD) and 1,4-bis{4-[9-(3,6-(di-tert-butyl)carbazoyl)]phenyl}durene (Me₃CCPD), which are derived from 4,4′-bis(9-carbazolyl)biphenyl (CBP) by inserting durene in its biphenyl core, are designed and synthesized for use as host materials for blue phosphors in organic LEDs (OLEDs). Inserting durene in biphenyl causes a right-angle torsion between the durene and the adjacent Ph groups due to the strong steric hindrance effect of the durene group, confining the effective π-conjugation on only one carbazole and 1 Ph and increasing the triplet energies of CPD and Me₃CCPD to >3.0 eV. These durene-decorated mols. show higher thermal stabilities than many other CBP derivatives Blue phosphorescent OLEDs were fabricated using CPD and Me₃CCPD as triplet hosts and traditional Ir(III) bis(4,6-(difluorophenyl)pyridinato-N,C^2′)picolinate (FIrpic) as a dopant and excellent performances were achieved. In particular, peak efficiencies of 26.2 cd A^-1 and 14.8 lm W^-1 were realized when CPD was used as both a host and exciton-blocking material. This is the 1st report using durene to tune the triplet energy levels of phosphorescent host materials. In the experiment, the researchers used many compounds, for example, 1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1HPLC of Formula: 3268-21-1).

1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1) belongs to iodide derivatives. Iodide-containing intermediates are common in organic synthesis, because of the easy formation and cleavage of the C–I bond. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.HPLC of Formula: 3268-21-1

Opening Metal-Organic Frameworks Volume 2: Inserting Longer Pillars into Pillared-Paddlewheel Structures through Solvent-Assisted Linker Exchange was written by Karagiaridi, Olga;Bury, Wojciech;Tylianakis, Emmanuel;Sarjeant, Amy A.;Hupp, Joseph T.;Farha, Omar K.. And the article was included in Chemistry of Materials in 2013.Safety of 1,4-Diiodo-2,3,5,6-tetramethylbenzene This article mentions the following:

Solvent-assisted linker exchange (SALE) was performed on a pillared-paddlewheel metal-organic framework (MOF), SALEM-5, to achieve incorporation of longer linkers into the material. The 9-Å meso-1,2-di(4-pyridyl)-1,2-ethanediol pillar of SALEM-5 was successfully replaced by 11-Å, 14-Å, and 17-Å pillars to generate daughter MOFs SALEM-6, SALEM-7, and SALEM-8. The daughter frameworks possess more open cages, as was demonstrated by structural modeling from the powder x-ray diffraction patterns, and larger solvent accessible space, as was demonstrated by TGA. Finally, a study was performed to examine the effect of pK_a of monoprotonated dipyridyl pillars (as an indicator of the Zn-L bond strength) on the outcome of SALE. In the experiment, the researchers used many compounds, for example, 1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1Safety of 1,4-Diiodo-2,3,5,6-tetramethylbenzene).

Transformation of photophysical properties from solution to solid state in alkoxy-cyano-diphenylacetylene molecules was written by Karunakaran, Venugopal;Prabhu, Deepak D.;Das, Suresh;Varughese, Sunil. And the article was included in Physical Chemistry Chemical Physics in 2015.Recommanded Product: 4-Iodo-1,2-dimethoxybenzene This article mentions the following:

Detailed photophys. properties of cyano and mono (MA)/bis alkoxy (DA) substituted diphenylacetylene moieties with different alkyl chain lengths (Me (1), octyl (8) and dodecyl (12)) were investigated in solution and the solid state in an effort to determine the effect of self-aggregation on these properties. The solvated mols. showed a minimal bathochromic shift with an increase of solvent polarity in their absorption spectra, whereas a significant shift was observed in the emission spectra. This could be attributed to the relatively low change in dipole moment between ground and Franck-Condon excited states and luminescence arising from the intramol. charge transfer state with a dipole moment significantly higher than that of the ground state. In solid state the emission quantum yields of these materials were significantly higher than in solution For DA1, polymorphic materials with distinct photophys. properties were obtained. The DA1 materials obtained by fast precipitation (DA1) showed broad fluorescence with peaks at 398, 467 and 535 nm upon excitation at different wavelengths. Detailed anal. of absorption, emission and excitation spectra and lifetime experiments indicated that these peaks could be attributed to the monomer, J- and H-type aggregates resp. Whereas the crystals obtained by slow crystallization (DA1C) showed only one emission peak at around 396 nm attributed to the monomer. This is supported by the single crystal X-ray structure which consists of a monomer mol. having minimal interaction with nearest neighbor mols. In the experiment, the researchers used many compounds, for example, 4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2Recommanded Product: 4-Iodo-1,2-dimethoxybenzene).

Triple neg. breast cancer (TNBC) remains a serious unmet medical need with discouragingly high relapse rates. The authors report here the synthesis and structure-activity relationship (SAR) of a novel series of 2,4,5-trisubstituted-7H-pyrrolo[2,3-d]pyrimidines with potent activity against TNBC tumor cell lines.
