Synthetic Main Group and Transition Metal Targets for Electronic and Photovoltaic Applications Open Access

[摘要] The work presented herein is focused on the synthesis and characterization of inorganic materials for potential use in electronic and photovoltaic applications. Platinum containing complexes of the form LxPt(SC4H2Br)2 (x = 1, L = dppe, dppp; x = 2, L = PBu3, PAr3), were synthesized using methods adapted from established literature procedures. The complexes were tested for their ability to undergo polymerization using known cross-coupling techniques. Polymers with molecular weights ranging from 3500 - 38 000 g/ mol were obtained. We were unable to purify the polymeric materials due to high solubility of the crude product in all organic solvents. Boron nitride (BN) is a ceramic with hardness akin to diamond in its cubic form, and has an exceptionally high thermal conductivity, making it ideal as a heat transfer agent in microelectronics. We began looking at molecular boron nitride systems by isolating inorganic analogues of ethene (H2BNH2), in the form of donor-acceptor adducts of the form LB-H2BNRR;;2-BH3 (LB = DMAP, IPr, IPr=CH2 and R, R;; = H, H; Me, Me; H, tBu). Preliminary dehydrogenation chemistry was performed with [Rh(COD)Cl]2 and MBr2 (M = Cu, Ni), to yield borazine as a byproduct, suggesting the presence of HBNH as an intermediate species.
