Sterically driven electronic properties of naphthalene- and anthracene-end-capped 2,2′-bipyridine luminophores: synthesis and density functional theory
摘要:
Two naphthalene- and one anthracene-end-capped 4,4'-pi-conjugated-2,2'-bipyridine chromophores have been synthesized via the Horner-Wordsworth-Emmons reaction protocol and their electronic absorption and emission properties have been examined. DFT and TD-DFT computational studies have been carried out in order to comprehend the role of steric factor over the electronic factor. (C) 2011 Elsevier Ltd. All rights reserved.
