“…8,9 In the last few decades, perylenediimide (PDI) as an important fluorescent molecule of rylene diimide family has drawn a great attention in the field of analytes and detection of small molecules. 10,11 In the year 1913, PDI was synthesized by Kardos 12 for the first time and he showed its application in industry as a dye material 13 owing to its poor solubility and excellent photostability. Beside this, it has other applications in the wide range of fields such as bioimaging, 14 optoelectronic devices, 15,16 organic photovoltaic, 17 organic solar cells, 18 dye-based laser, 19 organic light emitting diodes, 20 and organic field effect transistors.…”

A dipeptide‐appended perylenediimide (PDI‐CFF) fluorescent molecule was designed, synthesized, and characterized. Though the molecule does not dissolve in any individual solvent, it dissolves well in an organic/water mixed solvent system such as tetrahydrofuran/water. This new fluorescent molecule was self‐assembled in a tetrahydrofuran/water mixture to form both nanofibrous network structures and a nano ring structure. It has shown nanofibril morphology by the interactions with ferric ions (PDI‐CFF/Fe3+ system) with diminishing fluorescent property. Interestingly, L‐ascorbic acid (LAA) interacts with the PDI‐CFF/Fe3+ system, showing turn‐on fluorescence. Another interesting feature is that the minimum detection limits for Fe3+ ions and LAA are at the submicromolar levels of 6.2 × 10−8 and 3 × 10−8 M, respectively. Moreover, the fluorescent (10 μM) signals can be monitored by the naked eye under handheld UV lamp irradiation at 365 nm, and this is very convenient for the real application. In this study, the molecule offers the opportunity for processing these sequential fluorescence responses in order to fabricate a implication logic gate that includes NOT, AND, and OR simple logic gates using chemical stimuli (ferric ions and LAA) as inputs and fluorescence emission at 536 nm as output. The detailed mechanism of interactions of Fe3+ with PDI‐CFF and LAA with the PDI‐CFF/Fe3+ system is vividly studied by using Fourier transform infrared (FT‐IR) analysis and fluorescence. Moreover, this new molecule was reusable for several times without significant loss of its activity. The construction of logic gates using biologically important molecules/ions holds future promise for the design and development of new bio‐logic gates.

“…In continuation of our interest in molecular recognition of analytes using p-conjugated aromatic imide, [33][34][35][36][37][38] herein, we have designed an NPG derivative built from 1,8-naphthalimide and pentaethylene glycol for complexation with Pd 2+ ions. NPG showed high affinity for Pd 2+ ions with a limit of detection as low as 75 nM in HEPES buffer-DMSO (1 : 1, pH 7.2) solution.…”

“…[26][27][28][29][30] However, the polyethers attached to 1,8-naphthalimide fluorophore for recognition of heavy metals ions in aqueous medium and as developers for fingerprint imaging are scarcely known. [31,32] In continuation of our interest on π-conjugated imide chemistry for detection of Pd, Fe species and other heavy metal ions, [33][34][35][36][37][38][39][40] herein, we have synthesized pseudo-crown ether functionalized 1,8-naphthalimide (NHG) using literature procedure. The fluorescence spectrum of NHG showed decrease in the fluorescence intensity at 457 nm upon addition of Pd 2 + and Fe 3 + ions in 70 % HEPES buffer-DMSO (pH 7.2) solution with detection limit as low as 2.5 and 15 nM, respectively.…”

The development of coordination‐based host for the detection of heavy metal ions in aqueous medium is a challenging task. We report 1,8‐naphthalimide‐based pseudo‐crown ether host which possess hexaethylene glycol chain for the selective binding of Pd2+ and Fe3+ with higher affinity for Pd2+ over Fe3+ ions. The lowest detection limits for Pd2+ and Fe3+ ions are 2.5 nM and 15 nM, respectively. Job's and Hill plot showed 1 : 1 stochiometric complexation between NHG:Mn+ with binding constants of 1.4×104 M−1 (Pd2+) and 1.5×103 M−1 (Fe3+). The CIE plot of NHG showed 90 % blue colour purity in CHCl3 solution. In solid‐state, the CIE plot of NHG showed blue‐green colour with 52.7 % green colour purity and high quantum yield (ϕ=0.0643). The flake‐like aggregates of NHG transformed into spherical structure upon interaction with Pd2+ as confirmed by microscopic and light scattering studies.
