Synthesis and Study of Arylenevi Aryleneimine-Type Polymers Containing N-Hexyl-3.6-Carbazolyl Groups

as well as gel permeation chromatography and differential scanning calorimetry. sis of PPVs and they can be divided into direct or indirect methods. As direct meth-ods, polycondensation reactions (i.e., Wittig, Horner-Emmons, Knoevenagel, McMurry), dehydrohalogenation reactions and polymerization reactions, are better known, whereas the indirect methods are those using a soluble precursor polymer that by elimination of a Since the discovery of the electroluminescence property in poly(phenylenevinylene) (PPV) in 1990 by the Cambridge group [1], extensive studies have been carried out using this polymer class or other related polymer structures [2], as the active layer in constructio
