Abstract

In order to study the effects of solvent and ultrasonic irradiation on formation of [Tl(HTar)](1) and/or [Tl(Tar)](2), [HTar?=?(+)-tartaric acid] supramolecular polymers, we designed some experiments and synthesized four samples of 1 under the reaction of HTar and TlNOby sonochemical process and as the bulk samples. Nanostructures of compounds 1 and 2 as the bulk samples could be synthesized without ultrasonic irradiation, too. In the presence of ultrasonic waves, with acetonitrile solvent, more discrete nanoparticles were obtained. These four samples have been used as new precursors for preparation of thallium(III) oxide nanostructures via solid-state thermal decomposition process. There is a direct relationship between the morphology of initial precursors and resulting thallium(III) oxide nanostructures. These nanostructures were characterized by IR spectroscopy, X-ray powder diffraction (XRD) and Scanning Electron Microscopy (SEM).

Thallium

See more Thallium products. Thallium (atomic symbol: Tl, atomic number: 81) is a Block P, Group 13, Period 6 element with an atomic weight of 204.38. Thallium Bohr ModelThe number of electrons in each of thallium's shells is 2, 8, 18, 32, 18, 3 and its electron configuration is [Xe] 4f14 5d10 6s2 6p1. The thallium atom has a radius of 170 pm and a Van der Waals radius of 196 pm. Thallium was discovered by Sir William Crookes in 1861 and first isolated by Claude-Auguste Lamy in 1862. Thallium is a post-transition metal that is not found free in nature. Thallium is primarily used for its electrical conductivity as thallium sulfide, which changes with exposure to infrared light. This ability makes the compound useful in photocells. Elemental ThalliumThallium bromide-iodide crystals have been used as infrared optical materials. Thallium has also been used with sulfur, selenium or arsenic to produce low melting glasses which become fluid between 125 and 150 °C, while thallium oxide has been used to produce glasses with a high index of refraction, and is also used in the manufacture of photo cells. Its name is derived from the Greek word thallos, which means twig or green shoot.
