A luminescent Pt-POCN pincer complex via direct cyclometalation
摘要:
We report the synthesis of the novel pincer complex kappa(P),kappa(C),kappa(N)-[2,6-(iPr(2)PO)-(C6H3)(CH2[c-N(CH2)(4)O])]PtBr (Pt(POCN)Br, la) by direct cyclometalation of PtBr2(SEt2)(2.) This represents the first report of a mixeddonor platinum pincer complex synthesized using cyclometalation. The complex is emissive in the solid state and frozen solution. Comparison of the structure of la to related pincer complexes provides insights into the effect of pincer arm donor substituents on cyclometalation. (C) 2015 Elsevier By. All rights reserved.
