{"product_id":"9783832542306","title":"Synthesis and Characterization of Luminescent Cu(I) Complexes","description":"\u003cp\u003eLuminescent Cu(I) NHetPHOS complexes are very efficient emitters, which have successfully been deployed in organic light-emitting diodes (OLEDs). In this work, various important questions concerning Cu(I) complexes were addressed. By means of soft x-ray spectroscopy at the N K edge, ultraviolet photoelectron spectroscopy, and inverse photoemission spectroscopy, the electronic structure with particular focus on the occupied and unoccupied molecular orbitals, formed upon binding of the Cu- and N-atoms, and the HOMO and LUMO energies of these materials were investigated. Furthermore, new red-emitting Cu(I) complexes were developed. The principle structure of a not crystallizable NHetPHOS complex with a bridging bisphosphine ligand, yielding a new quantum efficiency record for both solution- and vacuum-processed organic light-emitting diodes with Cu(I) complexes as emitters, was determined by means of x-ray spectroscopy at the Cu K edge. Consequently, a breakthrough for the cost- and energy-efficient processing of organic light-emitting diodes from solution was enabled.\u003c\/p\u003e","brand":"Logos Verlag Berlin","offers":[{"title":"Default Title","offer_id":47062077833456,"sku":"9783832542306","price":55.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9783832542306_p0.jpg?v=1763687597","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9783832542306","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
