Anomalous electron instability of polymers due to uniaxial pressure

The electrical properties of thin films of polyaromatic compounds— polyarylenephthalides—are highly sensitive to pressure. At anomalously low pressure, not exceeding 2 Χ 105 Pa, an insulator-metal phase transition is observed in test samples. The conductivity changes by 11 orders of magnitude at the point of the transition. A model of a Mott phase transition is proposed to explain this effect.
