Abstract: The photodegradation of trimethylsilyl substituted ZnPc in different organic solvents is of quai first order kinetic decay and the resulting species were analyzed by GC/MS spectrometer. The mechanism of the photodegradation was proposed. Solubility is the key factor affects the photofading of TMS substituted Pcs. The greater the solubility the faster the fading.

Key words: trimethylsilyl substituted Pcs, photodegradation, mechanism
