Abstract
The photo-oxidation of toluene sulphonate polydiacetylene single crystals has been studied by scanning and transmission electron microscopy. Submicron particles were observed as reaction products on the surfaces of crystals which had been exposed to 514 nm light from an argon ion laser. Electron diffraction showed that these particles were single crystals ofparatoluene sulphonic acid. The appearance of the particles was correlated with the decrease in intensity of a Raman line associated with the presence of adsorbed oxygen on the crystal surface.
