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.
