Features of Gas-Sensibility of Dyes on the Base of 4-Valence Stannum Complexes

Abstract: Анотація. Досліджено вплив наявності у довкіллі аміаку або парів хлористого водню на фотолюмінесцентні властивості ансамблю наночастинок барвників на базі комплексів 4-валентного стануму. Виявлено, що чутливими до аміаку є барвники, що містять аміновий замісник бензоїльного типу у гідразонному фраґменті, а до хлористого водню-барвники із гідроксильним замісником. Обидві групи сполук суттєво зменшують інтенсивність свого світіння при наявності у І. К. Дойчо, С. А. Гевелюк, Я. І. Лепіх, Е. Ришякевич-Пасек 32 дов… Show more

“…In addition, the interaction of the substituent with the coordination node also increases the luminescence intensity and the stronger the closer is the substituent to the coordination node. Therefore, the dyes luminescence with substitution in position "2" (or "6") is always more intense than when substituted in position "3" (or "5") [14].…”

“…However, the ingress of the sample formed under these conditions into the ammonia medium should lead to an increase in the nitrogen concentration in the pores, which is equivalent to the creation of a nanoparticle ensemble at a saturating solution concentration exceeding the limit. This will reduce the luminescence intensity of the sample [4,[24][25].…”

“…Highly dispersed ensembles of nanoparticles with a well-developed surface should be useful, first of all, as active elements for gas sensors. Nanoparticles' ensembles of dyes based on tetravalent stannum are especially applicable in this sense [19][20]. The molecules of these substances consist of two parts: a coordination node, which is a complex set of benzene rings, and a hydrazone fragment, which consists of one benzene ring located outside the coordination node and connected to it by an ordinary C-C bond.…”
