This paper describes the synthesis of a new thermally cross-linkable hole-transporting poly(fluorene-co-triphenylamine) (PFTV) by Suzuki coupling reaction and its application in polymer light-emitting diodes (PLEDs). The characteristics of PFTV were analyzed by 1 H NMR, differential scanning calorimetry, optical spectroscopy, cyclic voltammetry, and atomic force microscopy. Its HOMO level...
This paper demonstrates synthesis of hyperbranched polymers (HTP and HTPOCH 3 ), containing triphenylamine moieties in main chain and thermally cross-linkable periphery or terminal vinyl groups, and application as hole-transporting layer (HTL) in multilayer light-emitting diodes. Absorption and photoluminescence (PL) spectroscopy, cyclic voltammetry (CV) and differential scanning calorimetry...
Poly(9-vinylcarbazole-co-4-vinyltriphenylamine)s, PVKT21 and PVKT45 with 21 mol% and 45 mol% pendant triphenylamine groups respectively, were electrochemically deposited as crosslinked thin films through electrocoupling of pendant triphenylamine moieties during the oxidation process. The electrocoupling process has been elucidated by electrochemical and spectroelectrochemical investigations which...
