Abstract

Abstract 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 1 H 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 ...
