2014 We have obtained X-ray diffraction patterns from the mesomorphic phase of two derivatives of terphenylene. The observations agree with the structure already proposed for the mesomorphic phase of a similar molecule : the molecules are stacked in columns and the columns form a regular hexagonal array. In addition it is possible to give a more accurate description of the positions of the terp...

Synthesis of 5,7-phenylquinoline from the Skraup reaction of m-terphenyl-amine and glycerol in the presence of acid is reported. Further reaction of 5,7-diphenyl-quinoline with phenyl lithium prepared in situ led to the formation of 2,5,7-triphenyl-quinoline. All of the products and their intermediates were characterized and the UV-Vis and photo-luminescence (PL) spectra of m-terphenylamine, 5,...

This paper deals with the synthesis of three up to date not described 4-(£>-terphenylyl)isothiocyanates and their six intermediates, two of which having not been described, too. A procedure was developed to identify £>-terphenyl derivatives by means of thin layer chromatography on alumina, as well as by gas chromatography. Infra-red and ultra-violet spectra were taken of the synthetized 4-(30-t...

Poly(alkyl-terphenyl piperidinium) ionomers and membranes were used for H2–O2 anion exchange membrane fuel cells, achieved a high power density of 2.58 W cm−2, which is new record polyaromatic-based cells. Details the study are described by Young Moo Lee co-workers in their Research Article on page 7710.

Wavelength shifter materials like pTerphenyl and Tetra Phenyl Butadiene (TPB) of thicknesses between 65 and 250 μg/cm have been studied in order to improve the quantum efficiency (QE) of a photomultiplier in the UV range. The best result has been obtained for p-Terphenyl of 100 μg/cm thickness. In this case the quantum efficiency integrated over a broad range of photon energies up to 6.2 eV sho...

A series of ether-free poly(p-terphenyl piperidinium)s carrying both cationic and zwitterionic groups were prepared evaluated as anion-exchange membranes (AEMs). First, a monomer (zwPip) was synthesized by sulfoalkylation N-methyl-4-piperidone (Pip) using 1,4-butane sultone. Pip zwPip then employed in superacid-mediated polyhydroxyalkylations with p-terphenyl to prepare precursor copolymers con...

In this paper we study quality of three types organic scintillators stilbene, p-terphenyl and EJ-299-33. We used monoenergetic neutron fields with a wide range energies in PTB Braunschweig. All the tests were carried out NGA-01 spectrometer. The results measurements are evaluated spectra from discuss each scintillator, such as FWHM peaks.
