Polymers Incorporating Low-Valent/Low-Coordination Number Main Group Centres: Novel, Multi-Functional Materials

Abstract

The PI has successfully accomplished the research goals as proposed. The initial aim of this program to develop highly novel examples of 'inorganic polymers' where the backbone elements would be expanded to other elements to include metals. The PI proposed that these topical and highly reactive materials will most likely exhibit unusual, and potentially applicable, electronic, optical, catalytic, charge storage and/or synthetic properties. The PI targeted polymers incorporating low oxidation state group 2 (e.g. MgI) or group 14 (e.g. SiI, GeI or SnI) metal-metal single/multiple bonds within the backbone chain, in addition to two-coordinate heavier group 14 elements, i.e. heavier carbene analogues (:EIIR2), within the chain. These were to be accessed utilizing unique reduction methodologies developed at Monash, previously utilized in the preparation of the monomeric counterparts of the targeted polymers. Furthermore, the researchers aimed to prepare and stabilize the phosphorus analogues of linear unhindered polyactelynes, i.e. {-P=C(R)-}n (R = H, Me etc.), by initial entrapment of phosphaalkynes (P-triple bond-CR) within suitable 1dimensional channels of zeolites and metal organic frameworks. This was to be followed by thermal, photolytic or metal-induced polymerization of the phosphaalkyne, yielding polymers, which should be protected from undergoing cyclization reactions by the constraints of the solid state host. This 3 year grant yielded 13 peer reviewed scientific papers, 8 conference presentations and multiple collaborations with other academic and DoD agencies.
