Abstract
The present invention provides a method for synthesizing a new class of inorganic-organic polymeric materials. These polymers are made with a backbone comprising chalcogenide elements such as sulfur, selenium, and/or tellurium along with organic crosslinking moieties that determine its physical and optical properties. Also disclosed are the related polymeric materials. These polymers are suitable for optical applications in short wave infrared (SWIR, 1-3 μm) and mid wave infrared (MWIR, 3-8 μm) regions.
