Crystal growth and characterization of 1,3,5-triphenylbenzene organic scintillator crystal

Metal-Free Amine-Anchored Triazine-Based Covalent Organic Polymers for Selective CO2 Adsorption and Conversion to Cyclic Carbonates Under Mild Conditions

“…The appearance of the CC and CN stretching bands in both CTP-1-NH 2 and CTP-2-NH 2 , as well as the disappearance of the C–Cl band, indicate the successful formation of polymer networks. In addition, the N–H stretching bands at 3440 cm –1 and C–H stretching bands at 3030 cm –1 also supported the formation of the expected CTP-X-NH 2 networks. − …”

Crystal Growth by Unidirectional Method ‐ A Generalized View on the Crystalline Perfection of the Uni‐Indexed, Bi‐Indexed, and Tri‐Indexed Plane Single Crystals

“…Govindan et al., have reported the 1,3,5‐triphenylbenzene single crystal and found a couple of satellite peaks that indicate the occurrence of the relative lattice disorder. [ 25 ] In addition to that, as per the ref [27] the bi‐indexed crystal does not have any HRXRD or XRD results to confirm the degree of crystalline nature. More importantly, Sankaranarayanan et al., have grown (110) plane benzophenone crystals and observed one satellite peak along with a major broad diffraction curve wherein the full width at half maximum is 61 arc sec.…”

“…Benzophenone (110) was the first crystal grown by the SR method [ 7 ] and from thereon, numerous researchers have reported their respective crystal growth findings and the functional properties of the grown crystals. [ 8–29 ] For example, Balamurugan et al. have reported the crystal growth of KDP by the SR method along the uni‐indexed plane of (200) and obtained good crystalline perfection [ 8 ] that are also reflected in the crystals of L‐alaninium p‐toluenesulfonate (010), [ 9 ] Triglycine sulfate (001), [ 10 ] triglycine sulfate (010), [ 11 ] Sodium sulfanilate dehydrate (001), [ 12 ] Methyl 2‐amino‐5‐bromobenzoate (001), [ 13 ] ammonium dihydrogen phosphate (200), [ 14 ] benzophenone (100), [ 15 ] benzil (100), [ 16 ] nickel sulfate hexahydrate (004), [ 17 ] and ammonium dihydrogen phosphate (100), [ 18 ] D‐π‐A type 2‐amino‐ 5‐nitropyridinium dihydrogen phosphate (001), [ 19 ] Imidazolium L‐Tartrate (010), [ 20 ] strontium bis (hydrogen L‐malate) hexahydrate (010), [ 21 ] sulfamic acid (100), [ 22 ] L‐alaninium p‐toluenesulfonate (010), [ 23 ] and Triglycine calcium dibromide (001).…”

[ 24 ] Comparatively low number of bi‐indexed crystals were grown by the SR method and they are benzophenone (110) [ 7 ] 1,3,5‐triphenylbenzene (011) [ 25 ] l‐Glutamic acid hydrobromide, [ 26 ] 4‐hydroxy l‐proline (110) [ 27 ] t‐stilbene, [ 28 ] ammonium dihydrogen phosphate (101), [ 29 ] and potassium dihydrogen phosphate (101). [ 29 ] Tri‐indexed plane crystal growth of ninhydrin (111) [ 30 ] by the SR method has been reported by Neelam Rani et al., and such kind of tri‐indexed crystal growth by the SR method is rare and we have found, to date, only one report in this regard.…”

Decomposition of Unpolarized Fluorescence Spectrum of Uniaxially Oriented 1,3,5-Triphenylbenzene Microcrystals Into Polarized Fluorescence Spectra

“…Therefore, TPB is a good choice for studying fundamental aspects of uorescence anisotropy. Although TPB can form large single crystals [23], magnetically oriented TPB microcrystals were used in this study so that the crystal axis is aligned in one direction with respect to the consolidating solid matrix. The magnetic technique is of great help when we only have microcrystals under investigation.…”
