“…The peripheral functionalization of dendrimers with different chromophores such as dansyl sulfonate [15,16], pyrene [17], azobenzenes [18], and coumarin [19,20] moieties and their potential applications have been described. Our previous works have been focused on the functionalization of poly(amidoamine) [21][22][23][24][25][26][27][28][29][30] and poly(propylene amine) [31][32][33][34] dendrimers by 1,8-naphthalimide chromophor groups and studied their potential as sensors for transition metal cations and pH.…”

A new water-soluble poly(propylene imine) dendrimer (PPI) modified with 4-sulfo-1,8-naphthalimid units (SNID) and its related structure monomer analog (SNIM) has been prepared by a simple synthesis. The aqueous solution of the monomer exhibited aggregation-induced emission (AIE) at 395 nm, while the dendrimer emitted at 470 nm due to an excimer formation beside the AIE at 395 nm. Fluorescence emission of the aqueous solution of either SNIM or SNID was significantly affected by traces of different miscible organic solvents, and the limits of detection were found to be less than 0.05% (v/v). Moreover, SNID exhibited the function to execute molecular size-based logic gates where it mimics XNOR and INHIBIT logic gates using water and ethanol as inputs and the AIE/excimer emissions as outputs. Hence, the concomitant execution of both XNOR and INHIBIT enables SNID to mimic digital comparators.
