New derivatives of the benzo[de]isoquinoline-1,3-dione system containing an amino group were synthesized by the reaction of 2-benzyl-6-bromobenzo[de] isoquinoline-1,3-dione with ethylenediamine and hydrazine. Further functionalization of the free amino groups leads to imines, amines, thioureas, and hydrazones. Some compounds exhibit high chemosensor selectivity in the determination of anions.

A fluorescent bischromophoric dyad combining anthracene and naphthalic anhydride units has been synthesized and characterized. The dyad shows a FRET mediated emission signal at ～535 nm when excited at λex. = 380/360 nm, with efficient energy transfer efficiency (ET = 93%) and quantum yield (Φ = 0.155). Upon interaction with F- and Hg 2+ ions selectively, a diminished (switched-Off) FRET signal is observed and the naked-eye sensitive color of the solution changed to dark red with enhanced emission corresponding to an anthracene moiety (switched-On). Job's plot analysis revealed a 1:1 stoichiometry between dyad and F -/AcO- and Hg2+ ions. The output fluorescence signals exhibited by dyad on chemical inputs of F-, AcO- and Hg2+ ions mimicked OR, XNOR and INHIBIT logic functions. A 1H NMR titration experiment suggested deprotonation of -NH proton and "Y-type or tweezer-like" H-bonding interaction in the presence of F- and AcO-, respectively, involving -NH, -CHN- and anthracene ring protons.
