by which molten sulfur can
be combined with comonomers to form stable polymers termed “organically
modified chalcogenide” or “ORMOCHALC” polymers.
One advantage to ORMOCHALC polymers is that they can possess important
optical properties, such as high refractive index and strong infrared
(IR) transmission, while being easier to fabricate than glass materials
with similar optical properties. In the present work, a new ORMOCHALC
is fabricated by using tetravinyltin as a comomoner with sulfur. This
is the first example of an organometallic molecule being used as a
comonomer to develop ORMOCHALCs. The result is an ORMOCHALC polymer
that has the highest refractive index reported for a “sulfur
and comonomer” polymer and that demonstrates unprecedented
transmission in the IR region.
