Tropylium ions fused with heterocyclic systems were synthesized to measure their reduction potentials of - 015 to - 0.37 V vs SCE. Radical anion of TCNQ and these tropylium ions formed charge transfer complexes, which have conductivities of σ = 10-4 - 10-7 Scm-1, suggesting that the belong to semiconductors.
