We have recently synthesised a random poly(meta/para phenylene) (PMPP) by a
n electrochemical method from p-methoxytoluene and fractionated on three-ch
ain length compounds. Moreover, these fractions can be deposited by vacuum
sublimation on indium tin oxide (ITO) substrates. Various characterisation
methods are allowed which facilitated the understanding of the structural,
electronic and optical properties of the PMPPs and a tentative of their cor
relation to chain length was presented. (C) 2000 Elsevier Science S.A. All
