ABSTRACT
The substituent effect on photochemical hole burning (PHB) for tetraphenylporphine was studied and the PHB efficiency was related to the electron donating and/or withdrawing properties of the substituents of the phenyl ring. The Hammett-sigma constants of the substituents were related to the efficiency of the photochemical hole burning reaction. Compounds with a low Hammett-sigma constant such as tetra-(4-methoxyphenyl)porphine had a higher PHB reaction efficiency than derivatives with a higher value such as tetraphenylporphine. We have also demonstrated multiple photochemical hole burning using this high efficiency compound tetra-(4-methoxyphenyl)porphine as a guest material.

    The oscillations of the ballistic hole current through a thin base of a p[sub +]pp[sub +] diode compressed uniaxially in the direction of the current are investigated theoretically. As a result of compression, the hole dispersion relation contains sections with negative effective mass along the...
