- Abstract
- The effects of molecular structure on the redox properties' are explored by the cyclic voltammetry and spectroscopy using the thin films of organic electroluminescence materials of poly(9,9'-dioctyl-2,7-fluorenediyl vinyleneco-9-cyanamide-2,7-fluorenediyl vinylene); PFVYCFV poly(9,9-dioctyl-2, 7-fluorenediyl vinylene 2,5-dicyano-1,4-phenyl vinylene); PFVDPV and poly(9,9'-dioctyl-2,7-fluorenediyl vinylene 2,3,5,6-tetracyno-1,4-phenyl vinylene); PFVTPV The PFVYCFV PFVDPV and PFVTPV show the UV/visible absorption maxima at 413 nm, 448 nm and 400 nm, respectively. Photoluminescence (PL) of these materials is blue-green color. The measured electrochemical ionization potential and electron affinity of these materials are 5.72 eV/3.19 eV for PFVYCFV 5.79 eV/3.26 eV or PFVDPV and 5.62 eV/3.48 eV for PFVTPV The electochemical bisection (oxidation & reduction) energy gaps of PFVYCFV PFVDPV and PFVTPV about PL onset are 2.93 eV 2.97 eV and 3.08 eV that are 5.09 eV & 2.97 eV 5.89 eV & 2.92 eV and 6.17 eV & 3.09 eV with respect to vacuum level, respectively.
