The article was written by Nishide, Hiroyuki; Miyasaka, Makoto; Tsuchida, Eishun. The article contains the following contents:

Star-shaped poly(1,2-phenylenevinylene)s 4-substituted with multiple pendant phenoxyls were synthesized by polymerizing 2-bromo-4-(acetoxyphenyl)styrene in the presence of 1,3,5-triiodobenzene or 1,3,5-tris(3′,5′-diiodophenyl)benzene as the core via a simple one-pot Heck reaction and subsequent hydrolysis, phenolate formation, and heterogeneous oxidation ESR spectra indicated a delocalized spin distribution into the core parts of the star-shaped mols. The polyradicals were in a high-spin state at low temperature, and the ferromagnetic behavior was enhanced for the polyradical with a higher mol. weight Although an average S of 3 remained at 3/2 to 4/2, the polyradical of 1,3,5-Tris[poly(4-(3′,5′-di-tert-butyl-4′-hydroxyphenyl)- 1,2-phenylenevinylene)]benzene, even with a spin concentration of 0.8 spin/unit revealed an average S of 7/2 to 8/2. The 1,3,5-benzene core acted as an effective magnetic coupler to align the spins of the pendant phenoxyls through the star-shaped π-conjugated backbone. The experimental part of the paper was very detailed, including the reaction process of 3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl(cas: 29102-67-8Application In Synthesis of 3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl)

In 2014,African Journal of Biotechnology included an article by Parthiban, K.; Vignesh, V.; Thirumurugan, R.. SDS of cas: 29102-67-8. The article was titled 《Characterization and in vitro studies on anticancer activity of exopolymer of Bacillus thuringiensis S13》. The information in the text is summarized as follows:

The objective of the present work was to isolate and characterize the exopolymer producer from a marine environment. The exopolymer producing strain (S13) was identified as Bacillus thuringiensis S13. Characterization of exopolymer shows the presence of brominated compound responsible for cytotoxicity on lung cancer cell line (A549) on XTT assay. An in vitro study of bacterial exopolymer shows the presence of cytotoxic effects on cell lines. Further, active compound in exopolymer responsible for cytotoxicity has to be characterized. The exopolymer produced by B. thuringiensis S13, showed potent cytotoxic effects, and could be used as therapy in cancer after further studies. In the experiment, the researchers used 3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl(cas: 29102-67-8SDS of cas: 29102-67-8)

In 2018,Physical Chemistry Chemical Physics included an article by Peyrot, David; Silly, Mathieu G.; Silly, Fabien. Application of 29102-67-8. The article was titled 《X3 synthon geometries in two-dimensional halogen-bonded 1,3,5-tris(3,5-dibromophenyl)benzene self-assembled nanoarchitectures on Au(111)-(22×sqrt.3)》. The information in the text is summarized as follows:

The self-assembly of star-shaped 1,3,5-tris(3,5-dibromophenyl)benzene mols. on Au(111)-(22×sqrt.3) in a vacuum is investigated using scanning tunneling microscopy and core-level spectroscopy. Scanning tunneling microscopy shows that the mols. self-assemble into a hexagonal porous halogen-bonded nanoarchitecture. This structure is stabilized by X3-A synthons composed of three type-II halogen-interactions (halogen-bonds). The mols. are oriented along the same direction in this arrangement. Domain boundaries are observed in the hcp region of the herringbone gold surface reconstruction. Mols. of the neighboring domains are rotated by 180°. The domain boundaries are stabilized by the formation of X3-B synthons composed of two type-II and one type-I halogen-interactions between mols. of the neighboring domains. Core-level spectroscopy confirms the existence of two types of halogen-interactions in the organic layer. These observations show that the gold surface reconstructions can be exploited to modify the long-range supramol. halogen-bonded self-assemblies.

Miller, Timothy M.; Neenan, Thomas X.; Zayas, Roberto; Bair, Harvey E. published an article on January 29 ,1992. The article was titled 《Synthesis and characterization of a series of monodisperse, 1,3,5-phenylene-based hydrocarbon dendrimers including C276H186 and their fluorinated analogs》, and you may find the article in Journal of the American Chemical Society.Recommanded Product: 29102-67-8 The information in the text is summarized as follows:

The convergent synthesis of a series of monodisperse aromatic dendrimers having mol. diameters 15-31 Å is described. These materials consist of 4,10, 22, or 46 benzene rings linked sym. by σ-bonds. Increasingly large dendrimer arms are prepared stepwise via Pd-catalyzed coupling of arylboronic acids to 3,5-dibromo-1-(trimethylsilyl)benzene. The aryltrimethylsilane is subsequently converted to a new arylboronic acid by reaction with BBr3 followed by hydrolysis. Coupling of arylboronic acid dendrimer arms to 1,3,5-tribromobenzene or 1,3,5-tris(3,5-dibromophenyl)benzene is the final step in the synthesis. A series of dendrimers consisting of 4, 10, and 22 Ph rings sym. arranged in which the outer Ph rings are fluorinated is prepared by a similar sequence of reactions. The largest hydrocarbon dendrimer is soluble to the extent of 190 g/L in PhMe and is stable to 500°.

The article was written by Brown, Gemma L.; Gardiner, John M.; D’Emanuele, Antony; Attwood, David; Gibb, Ryan. The article contains the following contents:

Dendrimers are a class of polymeric macromol. that are unique in that they have well defined, globular structures with high symmetry and low polydispersity. There has been recent interest in the synthesis of polyphenylene dendrimers due to their well defined, shape persistent architectures. In this study we have synthesized G0 and G1 polyphenylene dendrimers with shape persistent cores via a series of Suzuki cross coupling reactions and conversion of aryl bromides to boronic acid derivatives The dendrimers have been characterized by 1H and 13C NMR spectroscopy, mass spectrometry and elemental analyses. A crystal structure of the G0 methoxy-terminated dendrimer was obtained. We are currently using mol. modeling to investigate dendrimer topol. In conclusion a new set of rigid dendrimers with triphenylbenzene cores were successfully synthesized in high yields. In order to investigate a variety of topologies different cores are being synthesized, for example tetraphenylmethane and hexaphenylbenzene.
