Design, Photochemistry, Logic Gates Behavior and Antibacterial Evaluation of ICT Systems based on 1,8-naphthalimides.

Ace naphthene as a primary material was nitrated and further reacted by various processes such as oxidation, imidation and amination in order to obtain dyad 5. The dyad 5 fluoresces in solvents of different polarity and the emission is shifted bathochromically with increasing the solvent polarity due to ICT enhancement, The fluorescent enhancement is greatest in case of chloroform (ФF = 0.48) on excitation at 420 nm,The influences of the pH on dyad 5 were also investigated, The results can be considered as representing off-on-off states. Dyad 5 executes two input XNOR logic gates, towards H+ and HO- ions, "off-on-off" switching behavior between H+ and HO- ions was observed, The synthesized compounds were tested for antimicrobial activity of Gram-positive and Gram-negative bacteria, The compounds tested have a good antibacterial activity as compared with standard compound (Gentamycin).
