Synthesis of polyarylenephthalides prospective as smart polymers

Supramolecular structure of electroactive polymer thin films

“…This polymer has a molecular weight of (50-100) × 10 3 depending on the synthesis conditions. It is heat resistant (the softening temperature is ~440°C, and the temperature of the onset of decomposition is ~460°C) and soluble in conventional organic solvents, such as chloroform, methylene dichloride, cyclohexanone, etc., which permits the efficient purification of this polymer from impurities [4]. In a normal state, PDP is a dielectric material characterized by the following parameters: the band gap is ~4.3 eV, the electron affinity is ~2 eV, and the first ionization potential is ~6.2 eV [5].…”

Achievements in polycondensation and condensation polymers

“…These polymers were prepared by S.N. Salazkin et al [123] via the homopolycondensa tion of carboxylic acid pseudochlorides or their poly condensation with other monomers.…”

“…The increased interest in these polymers is related to their potential use as smart materials possessing the electric switching effect under the action of tempera ture, pressure, and external electric or magnetic fields [123,124].…”

Polymer Thin Film Chemical Sensors

“…In the early 1980s, a new polymer-poly(diphenylenephthalide) (Salazkin et al, 2008)-was synthesized at the Institute of Organic Chemistry (Ufa Research Center, Russian Academy of Sciences), which opened the way to synthesizing a number of new compounds. Its structural formula and optimized three-dimensional geometry are shown in Fig.…”
