4-Amino-1,8-dicyanonaphthalene derivatives as novel fluorophore and fluorescence switches: Efficient synthesis and fluorescence enhancement induced by transition metal ions and protons

A new electronic push-pull fluorophore, 4-amino-1,8-dicyanonaphthalene, and its derivatives have been synthesized efficiently. They can be used as photo-induced electron transfer fluorescence switches which exhibit considerable fluorescence enhancement induced by transition metal ions Cr3+ and Fe3+ and also respond to pH values very sensitively.

Synthesis of a hydrophilic naphthalimidedioxime

Imidedioximes are formed in hydroxylamine-treated polyacrylonitrile adsorbents used in the extraction of uranium from seawater. Although known to be a good uranophile, the glutarimidedioxime model compound 1 is rapidly hydrolyzed under acidic conditions used to elute metals from the adsorbent. This work reports the synthesis of a hydrophilic naphthalimidedioxime derivative 14, which is stable under acidic elution conditions. The synthesis starts from simple acenaphthenequinone 7 and converts it to a functional group dense imidedioxime 14 in 7 steps.
