We study, via density functional theory and time dependent DFT calculations, the photophysical processes of a styryl‐bodipy derivative, which acts as a three metal‐cation‐receptor fluorophore in order to (a) gain information on the appropriate computational approach for successful prediction of molecular logic gate candidates, (b) rationalize the available experimental data and (c) understand how the given combination of three different receptors with the BODIPY fluorophore presents such interesting optoelectronic responses. The fluorophore (1), its monometallic complexes (1‐Ca 2+, 1‐Zn 2+, and 1‐Hg 2+), and its trimetallic complex (2) are studied. The calculated λmax values for absorption and emission are in excellent agreement with experimental data. It was found that the observed quenching of emission of 1 and of the monometallic complexes is attributed to the fact that their first excited state is a charge‐transfer state whereas this does not happen for the complex 2. It should be noted that for the correct ordering of the excited states, the inclusion of corrections to the excitation energies for nonequilibrium solvent effects is required; while in the case of 1‐Ca 2+, the additional explicit inclusion of the solvent is necessary for the quenching of the emission spectra.

“…32 It is well-known that F -is present in many hypnotics and also in psychiatric drugs. 33 However, its presence in excess amounts in the human body is responsible for ill-effects, like osteoporosis, osteoarthritis, fluorosis and immune system disruption. 34 Its luminescent properties henceforth also merit mention for trace level (0.94 -7.5 ppm) fluoride sensing.…”

A time-cost effective, chemically stable mesoporous resin (FSG-PAN), simultaneous binder of two different metal centers (both high (Cd(II)) and low (Tl(I)) oxidation states), has been synthesized by immobilizing azo-dye (1-(2-pyridylazo)-2-napthol: PAN) on functionalized silica gel (FSG). Its corresponding synthesized nano material possesses good luminescent properties, and has been utilized in fluoride sensing at trace levels (1.8 × 10 -6 -7.2 × 10 -6 M). The composition.·51H2O) and structure (tetrahedral) have been well assessed. Under the optimum extraction conditions, the soft extractor (ηFSG-PAN = 1.31 eV), FSG-PAN quantitatively extracts the soft metal centers Cd(II), followed by Tl(I) at its respective HOMO and LUMO by soft-soft interactions. The extractor possesses a high Brunauer-Emmett-Teller (BET) surface area (SABET) (374 m 2 g -1 ), high preconcentration factor (PF, 192), selective pore size and two kinds of break-through capacity (BTCHOMO, 945 μmol g -1 ; BTCLUMO, 120 μmol g -1 ). BTC is spelled out as a function of the electron density over the ligand binding site as analyzed from a DFT calculation.
