FWF-Synt u FTIR Spektr v - Synthesis and FTIR Spectroscopy of Fluorinated Oligosilanes

Project: Research project

Description

The project envisages the synthesis of novel fluorinated disilanes and trisilanes such as F2HSiSiHF2, FH2SiSiH2F,
F2HSiSiH2F, FH2SiSiH2SiH2F or HF2SiSiF2SiF2H and of fluorinated carbosilanes such as CH2XSiF2H,
CH2XSiH2F, CHX2SiF2H, CHX2SiH2F (X = F, Cl, Br, I) oder CH2FSiH2CH2F and the investigation of the
preferred conformations of these molecules by Fourier Transform Infrared spectroscopy. These species represent
mixtures of conformers, whose concentration ratio varies with temperature. Recording the spectra at different
temperatures therefore allows the identification of bands belonging to individual conformers. From relative
intensities of bands, energy differences between conformers will be obtained. The experimental results will be
complemented by ab initio calculations of equilibrium geometries and vibrational frequencies.
