| Abstract: | Encapsulation of pyrrole in one-dimensional channels of AlPO4-5 and AlPO4-11 with chromium ions was attempted by a gas diffusion process and investigated by means of thermoanalytic, spectroscopic and conductivity methods. From the results, it was found that conducting polypyrrole was synthesized in channels of AlPO4-5 with chromium ions which acted as oxidizing agents. Polypyrrole, however, could not be occluded in channels of AlPO4-11 with chromium ions. |
