Abstract

UV irradiation of porphyrins in tetranucleotide-bisporphyrin arrays in organic solvents leads to selective bleaching of diphenyl porphyrins but not of tetraphenyl porphyrins. This was shown by absorbance and CD spectroscopy. The diphenyl porphyrin can be stabilised by duplex formation with a complementary PNA strand. These arrays are versatile building blocks for the synthesis of potential electronic arrays using a DNA scaffolding approach.
