A pellet-type optical nanomaterial of silica-based naphthalimide–DPA–Cu(ii) complexes: recyclable fluorescence detection of pyrophosphate†
Abstract
A pellet-type nanomaterial prepared from a mesoporous silica-immobilized naphthalimide–DPA–Cu(II) complex (MSIND–Cu) is investigated as a selective fluorescent chemosensor for PPi detection with a large “off–on” fluorescence change, low detection limit, short response time and a broad pH test range.
