, p. 1359 - 1363 (2019/02/06)
We have demonstrated a useful synthetic strategy to assemble star-shaped C3-symmetric molecules containing 1,3-azole moieties at the periphery. To generate these C3-symmetric heterocycles, we have employed the Pd/Cu-based coupling reactions. To this end, we have used benzoxazole, benzothiazole, and benzimidazole as coupling partners to generate the corresponding hetero-aryl Heck coupling products.
Synthesis of C3-symmetric star-shaped molecules containing α-amino acids and dipeptides via Negishi coupling as a key step

We demonstrate a new synthetic strategy toward star-shaped C3-symmetric molecules containing α-amino acid (AAA) derivatives and dipeptides. In this regard, trimerization and Negishi cross-coupling reactions are used as the key steps starting fr
Selective and reversible interconversion of nanosliders commanded by remote control: Via metal-ion signaling

A multi-device network mainly consisting of two two-component nanosliders was formed by self-sorting of six components. Addition/removal of zinc(ii) ions reversibly reorganized the network by chemical signaling involving the translocation of copper(i) from a relay station followed by the selective disassembly/assembly of one of both multi-component devices. The thus liberated machine parts served to erect a three-component nanoslider alongside the other unchanged two-component nanoslider.

A series of 1,3,5-triphenylbenzenes (TPBs) bearing various substituents have been made and their ability to form lithium solvated electron solutions (LiSESs) in tetrahydrofuran (THF) solution have been studied. It was found that the TPBs bearing electron
Sulfated tungstate catalyzed synthesis of C3-symmetric 1,3,5-triaryl benzenes under solvent-free condition

Sulfated tungstate catalyzed environmentally benign, simple, one pot, and solvent-free method has been developed for the synthesis of 1,3,5-triarylbenzenes via cyclic self-condensation of three molecules of aryl ketones. High yields, short reaction time, easy work-up procedure and recycling of the catalyst endorse advantage.

Three star-shaped derivatives of 1,3,5-triphenylbenzene bonded to fluorene moieties with various linking groups were designed and synthesized. The three dendritic compounds are characterized by high values of decomposition temperature (up to 434 °C) and f
Alcohol-soluble electron-transport small molecule for fully solution-processed multilayer white electrophosphorescent devices

A novel alcohol-soluble electron-transport material was designed and synthesized. This material not only possesses a high triplet energy and a low HOMO level but also exhibits excellent electron-transport properties and good film-forming ability. Efficien
Novel self-assembled 2D networks based on zinc metal ion co-ordination: Synthesis and comparative study with 3D networks
Rajwar, Deepa,Liu, Xinfeng,Lim, Zheng Bang,Cho, Sung Ju,Chen, Shi,Thomas, Jens M. H.,Trewin, Abbie,Lam, Yeng Ming,Sum, Tze Chien,Grimsdale, Andrew C.

The synthesis of linear and trigonal terpyridine bearing molecules (tpys) and their self-assembly to form novel extended self-assembled 2D networks of trigonal tpys with linear tpys through zinc metal ion (Zn2+) co-ordination is reported. The r
Modular syntheses of star-shaped pyridine, bipyridine, and terpyridine derivatives by employing sonogashira reactions
Trawny, Daniel,Kunz, Valentin,Reissig, Hans-Ulrich

A simple and flexible synthesis for a series of star-shaped pyridine, bipyridine, and terpyridine derivatives is reported by using a modular approach that combines the use of a ligand, spacer, and core unit. A fairly efficient method to prepare 4′-nonafloxy-functionalized terpyridine derivatives is described. The building blocks that contain the functionalized pyridine, bipyridine, or terpyridine derivatives were linked to different C3-symmetrical core units. In most cases, Sonogashira reactions were employed in the crucial final steps of the synthesis. A star-shaped dodecafluorinated compound was also prepared in a straightforward fashion. A simple procedure for the preparation of partially silylated 1,3,5-triethynylbenzene derivatives is presented, which provides an approach to C2-symmetrical star-shaped compounds that have only one terpyridine and two terphenyl units as "dummy" ligands. The absorption and emission spectra of the fully conjugated C3-symmetrical pyridine derivatives were systematically investigated, and fairly large Stokes shifts were observed.

A highly efficient and simple procedure for the synthesis of substituted benzenes is described. A broad range of ketones (alkyl-aryl ketones and cyclic ketones) were condensed via a cyclotrimerization reaction in the presence of catalytic amounts of boron sulfonic acid [B(HSO4)3], a new, highly efficient, and reusable catalyst, under solvent-free conditions. All reactions completed in short times without formation of any by-products. The catalyst was recovered and reused successfully for 15 cycles of the reaction. Copyright
