Dynamic characteristic of molecular structure of poly(ortho-methoxyaniline) with magnetic probes

The modern progress of bionanotechnologies and molecular electronics requires development of new organic materials with specific characteristics for formation of ultrathin films with specified magnetic or conductive properties. Here we need new experimental and computing methods creation. In this work a new effect is experimentally discovered in temperature behavior of electronic properties of the complex with a magnetic probe (iron ion) in poly(ortho-methoxyaniline) (PoMA). Using quantum chemical calculation we determine the structure of the magnetic probe's immediate environment. The electron structure of the polymer specifies peculiarities of its doping and charge transport. The iron magnetic probe allows measuring of the complex's electron structure dynamic characteristics in the polymer using the method of electron spin resonance for temperature range T = 4.2-295 K. The height of the barrier between the minima of potential of the intramolecular electric field of the complex is established.
