    Conjugated polymeric materials and their nanocomposites are widely used for the creation of alternative sources of renewable energy, cell phone screens, mobile gadgets, video players and OLED-TV, as well as organic diodes, transistors, sensors, etc. with field-dependent and spin-assisted electronic properties. Multifrequency EPR Spectroscopy methods can help researchers optimize their structural, magnetic and electronic properties for the creation of more efficient molecular devices. This book will acquaint the reader with the basic properties of conjugated polymers, the fundamentals of EPR Spectroscopy, and the information that can be obtained at different wavebands of EPR spectroscopy.

    Victor I. Krinichnyi was employed as a scientific researcher and a senior scientific researcher in the Institute of Problems of Chemical Physics RAS (former the above mentioned Institute of Chemical Physics in Chernogolovka RAS). His SciD (Physics and Mathematics) Thesis (Habilitation) titled "High resolution 2-mm wave band EPR spectroscopy in the study of biological and conducting polymers' was also successfully defended by 1992 in the same Institute where he works today as a leading scientific researcher and heads the High-Frequency EPR Group.
