A novel dendritic anion conductor: quaternary ammonium salt of poly(amidoamine) (PAMAM)

摘要

The quaternary ammonium salts of dendritic poly(amidoamine) generations 2 and 3 are prepared by methylation and quaternization with methyl iodide. The obtained dendritic anion conductors exhibit a conductivity of 10~(-5) - 10~(-6)S centre dot cm~(-1) at ambient temperature. The plots of conductivity vs. temperature are curves with the lowest point around 58deg C, which appear to exhibit a substantially different conductive law compared with ordinary linear or comb-like polyelectrolytes.
