Résumé

A new electroluminescent poly(p-phenylene) (PPP)-type polymer (CHALC-PPP) incorporating chalcone-type groups as side-chains has been synthesized via a chemical modification of a precursor acyl-functionalized polymer. The chemical structure of the polymer was characterized by (1)H NMR, (13)C NMR, and FT-IR spectroscopic analysis. CHALC-PPP contains a substitution ratio of 40% of vinylaryl groups. It is fully soluble in common organic solvents and has a number-average molecular weight of 3750 g/mol. CHALC-PPP thin solid film absorbs in UV and emits in the green region with a maximum at 512 nm. From the cyclic voltammetry analysis, the HOMO and LUMO energies levels values are -5.67 and -2.70 eV, respectively. A multilayer diode device with the configuration ITO/PEDOT:PSS/CHALC-PPP/BCP/Al emitting a green light has been fabricated. (C) 2011 Elsevier B.V. All rights reserved.
