Features of the Preparation and Luminescence of Langmuir-Blodgett Films Based on the Tb(III) Complex with 3-Methyl-1-phenyl-4-stearoylpyrazol-5-one and 2,2′-Bipyridine

In this study, we investigated the effect of terbium ions (Tb3+) on the subphases of the limiting area of the molecule for the complex compound (CC) TbL3 center dot bipy (where HL is 3-methyl-1-phenyl-4-stearoylpyrazol-5-one and bipy is 2,2 '-bipyridine). We examined the Langmuir monolayer and the change in the luminescence properties of TbL3 center dot bipy-based Langmuir-Blodgett films (LBFs). The analysis of the compression isotherms, infrared, and luminescence spectra of TbL3 center dot bipy LBFs was performed by varying the concentration of Tb3+ in the subphases. Our results demonstrate the partial dissociation of the CC at concentrations of C(Tb3+) < 5 x 10(-4) M.

Automated summary

In this study, the effect of terbium ions (Tb3+) on the subphases of a complex compound TbL3 center dot bipy was investigated. By varying the concentration of Tb3+, the compression isotherms, infrared, and luminescence spectra were analyzed. The results demonstrate partial dissociation at low concentrations of terbium ions.
