Among them triphenylene (Tp) seemed to be an interesting candidate. Triphenylides containing one, two or three alkali metal atoms (K, Rb, Cs) per Tp were synthesized. Only K salts had a semi-conductor like conductivity with a gap of 0.16 eV, all the others were insulators. Very weak LFMA signal was obtained for KTp at 4 K. A signal at g=4 was observed in the ESR spectrum of K2Tp and Rb2Tp. Infrared and Raman spectra of the solids are reported.Show less >
