Chromophore Specific Photoreactivity in 2,3,4-Tri(1,2-naphthoquinone-2-diazide-5-sulfonyl-oxy)-benzophenone

Different electronic structures for the three 1,2-naphthoquinone-2-diazide (NQD) chromophores in 2,3,4-tri(1,2-naphthoquinone-2-diazide-5-sulfonyl-oxy)-benzophenone were detected using 1H NMR spectroscopy.The NQD substituent in the o-position of the benzophenone is influenced by intramolecular through space interactions with the benzophenone part of the molecule.The change in the electronic structure is the reason for the obtained different photoreactivity of the o-NQD chromophore compared with m-NQD and p-NQD.The relative quantum yields of photolysis are 0.3 (o-NQD) and 0.9/1.0 (m-NQD/p-NQD).
