Abstract:

There is an increasing need for polymeric materials to be imbued with specific properties and function to address a wide range of emerging societal needs.  We have been developing to new classes of organic/inorganic hybrid polymers with specific electrochemical and optical properties to address technical challenges in sustainable energy and next generation optics, which we will discuss.  We will present our recent efforts on the synthesis of organic/hybrid polymers well-defined metallopolymers incorporating [Fe-Fe]-hydrogenase mimetic clusters via atom transfer radical polymerization as a route to improve the electrocatalytic activity of these materials for hydrogen evolution reactions (HER).  We have pursued the preparation of metallopolymers from the functional [2Fe2S] clusters via ATRP of various vinylic comonomers to introduce well-defined polymers to site isolate the complex as in the enzyme during electrocatalysis.  We will discuss in this presentation this new synthetic approach along with our recent electrocatalytic performance results of these novel metallopolymers.  We will then discuss our recent work on polymeric materials for emerging applications in infrared optical technologies.  Optical and imaging technologies with infrared (IR) light is an emerging frontier for a wide range of defense, civilian and transportation areas. Currently, there are only a select number of materials that are capable of transmitting, guiding, or reflectivity IR light.  In this talk, we will discuss our recent progress with a new class of IR optical polymers, termed, chalcogenide hybrid inorganic/organic polymers (CHIPs).  This new class of materials exhibit the highest refractive index (n ~  2.0) of any synthetic polymer in the NIR, SWIR and mid-IR, while also retaining excellent transparency.  We will discuss our recent efforts to prepare and process these materials into optical components for a variety of IR devices for thermal imaging and IR reflective coatings.
