Abstract :
Summary form only given. The new conjugated polymer poly(tetraphenylquinodimethans) (PTPhQ) with degenerate ground state has been obtained in linear (presumably 10) and not-work (presumably 2D) modification by the method of oxidative condensation of diphenylmethane or its chlorine derivatives in the presence of Lewis acids. The PTPhQ has all properties characteristic for conjugated polymers. The neutral form of 1D PTPhQ is soluble and films can be obtained from solutions. Transformation of PTPhQ from neutral to doped form is accompanied by changes in optical spectra and increasing of its conductivity. The doping of PTPhQ by Lewis acids is accompanied by appearance and growth of ESR signal. For example when the 1D PTPhQ is doped by SbCl/sub 5/ the ESR signal with g - value about 2, /spl Delta/ H = 7,2/sup 5/ - 7,9 Gauss and spin concentration more than 10/sup +22/ spins/mo] is observed. The very wide line ( > 5000 Gauss) without fine structure in spectra ESR is also observed.
