Small-molecule cyclotri-or cyclotetraphosphazenes and their linear high polymeric analogues bearing amino, phosphino, or organohalogeno side groups have been quaternized by treatment with methyl iodide or triphenylphosphine. Quaternization occurred at the side-group sites except with the piperidino derivatives, where the reactive sites were the skeletal nitrogen atoms. The quaternized species reacted with lithium 7, 7, 8, 8-tetracyanoquinodimethane (LiTCNQ) to generate TCNQ “simple salts”, and these (or their onium precursors) reacted with neutral TCNQ to generate the “complex salts”. The electrical conductivities of the cyclic trimeric phosphazene complex salts (10-3-10-2Ω- 1cm-1) were higher than those of their high polymeric counterparts.
