Point-contact spectra of organic conductors[(C2H5)4N]0.5[Ni(dmit)2]and(BEDT-TTF)2I3have been measured. The plots of point-contact functions of the electron–phonon interaction in these compounds have been constructed, and mean and root-mean-square values of frequency have been obtained. The relation between the intensity of the electron-vibrational interaction and conducting properties of the materials under investigation have been obtained. A correlation is observed between the intensity of these processes and the superconducting transition temperature. The criterion for the synthesis of new organic superconductors is discussed. ©1998 American Institute of Physics.
