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.

First claim

What is claimed as new and desired to be protected by Letters Patent of the United States is:

1 . A method to make an organically modified multicomponent chalcogenide polymer, comprising:
combining two or more chalcogenide elements to form an amorphous compound; annealing the amorphous compound to form a crystalline precursor; and adding a crosslinking moiety to the crystalline precursor to form the organically modified multicomponent chalcogenide polymer.

2 . The method of claim 1 , wherein the chalcogenide elements comprise any combination of sulfur, selenium, and tellurium.

3 . The method of claim 1 , wherein the chalcogenide elements comprise 60-99 atomic percent sulfur and 1-40 atomic percent selenium.

4 . The method of claim 1 , wherein the crosslinking moiety is polyvinyllic.

5 . The method of claim 1 , wherein the crosslinking moiety is diisopropenylbenzene.

6 . The method of claim 1 , wherein the crosslinking moiety is a halogenated divinyllic species, a dialkylvinyl species, a dithiol species, a polyvinyllic species, a polyalkynyl species or a metal or an inorganic compound comprising a divinyl, dithiol, dialkynyl, polyvinyl, polythiol, or polyalkynyl species.

7 . The method of claim 1 , wherein when adding the crosslinking moiety to the crystalline precursor, the crosslinking moiety comprises 10-50 weight percent and the crystalline precursor comprises 50-90 weight percent.

8 . An organically modified multicomponent chalcogenide polymer made by the method, comprising:
combining two or more chalcogenide elements to form an amorphous compound; annealing the amorphous compound to form a crystalline precursor; and adding a crosslinking moiety to the crystalline precursor to form the organically modified multicomponent chalcogenide polymer.

9 . The polymer of claim 8 , wherein the chalcogenide elements comprise any combination of sulfur, selenium, and tellurium.

10 . The polymer of claim 8 , wherein the chalcogenide elements comprise 60-99 atomic percent sulfur and 1-40 atomic percent selenium.

11 . The polymer of claim 8 , wherein the crosslinking moiety is polyvinyllic.

12 . The polymer of claim 8 , wherein the crosslinking moiety is diisopropenylbenzene.

13 . The polymer of claim 8 , wherein the crosslinking moiety is a halogenated divinyllic species, a dialkylvinyl species, a dithiol species, a polyvinyllic species, a polyalkynyl species or a metal or an inorganic compound comprising a divinyl, dithiol, dialkynyl, polyvinyl, polythiol, or polyalkynyl species.

14 . The polymer of claim 8 , wherein when adding the crosslinking moiety to the crystalline precursor, the crosslinking moiety comprises 10-50 weight percent and the crystalline precursor comprises 50-90 weight percent.

15 . A method to make an organically modified multicomponent chalcogenide polymer, comprising:
annealing a selenium or tellurium powder to form a crystalline precursor; and adding a crosslinking moiety to the crystalline precursor to form the organically modified multicomponent chalcogenide polymer.

16 . The method of claim 15 , wherein the crosslinking moiety is polyvinyllic.

17 . The method of claim 15 , wherein the crosslinking moiety is diisopropenylbenzene.

18 . The method of claim 15 , wherein the crosslinking moiety is a halogenated divinyllic species, a dialkylvinyl species, a dithiol species, a polyvinyllic species, a polyalkynyl species or a metal or an inorganic compound comprising a divinyl, dithiol, dialkynyl, polyvinyl, polythiol, or polyalkynyl species.

19 . The method of claim 15 , wherein when adding the crosslinking moiety to the crystalline precursor, the crosslinking moiety comprises 10-50 weight percent and the crystalline precursor comprises 50-90 weight percent.
