ESR studies were carried out in detail to investigate the changes of CuTAPP (cppper tetra-(p-trimethylanmoniumphyenl) porphine iodide) supported on active carbon during room temperature shelving and heat-treatment.Between room temperature and round 50℃, the resolution of the ESR spectra was found to vary with temperature and relative humidity reversibly. A mechanism of two-dimensional diffusion of the macrocyclic compound in the adsorbed liquid film was suggested to interprate the change in spectral resolution. The ESR spectra after heat-treat-ment at temperatures ranging from 150 to 600 ℃ were also reported and discussed briefly.
