click reactions (alkyne-azide coupling, thiol-ene addition) and Piers-Rubinstajn
reaction or more complex combined chemical modifications based on reaction
schemes in organic chemistry, thus showing that the field of functional silicone
materials is still in development.
Functional groups (electron donor, hydrophilic, mesogenic, photo-responsive,
polar, etc.) linked to low or high molecular weight, linear, cyclic or crosslinked
siloxane compounds, strongly influence their properties (electric, mechanical, surface, thermal properties, solubility and so on). Such compounds generally exhibit
self-assembly in selective solvents, or can act as biological-active compounds,
ligands, liquid crystals, surfactants, etc. In relation to the wide variety of chemical
structures and properties derived therefrom, the applications of modified siloxanes
are also increasingly explored and often more than one application is found for a
given compound.
