Publication date: 15 September 2018Source: Journal of Organometallic Chemistry, Volume 871Author(s): Fedor V. Drozdov, Georgij V. Cherkaev, Mihail I. Buzin, Aziz M. MuzafarovAbstractIn this paper, two simple methods of introducing an azodye into a siloxane matrix using hydrosilylation and azo coupling reactions are presented by the example of the model heptamethyltrisiloxane. It has been shown that the introduction of the bisazoevgenol fragment into the heptamethyltrisiloxane molecule results in the crystallization of the siloxane derivative. The obtained compound was studied by nuclear magnetic resonance (NMR) spectroscopy methods, polarization optical microscopy (POM) and differential scanning calorimetry (DSC).Graphical abstract
