摘要: Electronic spectral properties of tertiary butylphthalocyanine (TBH2Pc) in a 4.2 K n-hexadecane (C-16) matrix were investigated. A clear doublet in the 0-0 fluorescence region was recorded, representing a approximately 20 cm-1 Stokes shift due to a different proton geometry (molecular tautomerism) in the centre of the molecule. Photochemical interconversion between the tautomers was studied by the intensity variation of fluorescence bands as a function of time. The transformation saturated in several tens to two hundreds of milliseconds under our pumping conditions. Similar investigations of the complex in solid n-octadecane (C18) were also carried out on a less detailed scale. The results were compared with those for free base phthalocyanine (H2Pc) in a mixed solvent matrix of alpha-chloronaphthalene (alpha-ClN) and n-octane (C-8).
