“…This is due to the deviations in the values of the adjustable parameter “ a ” in the Stokes–Einstein relation and the approximated values of the atomic volume in the Edward′s empirical relation . A similar discrepancy was observed in other studies. − Hence, we can conclude that the finite sink approximation model helped us only to extract D and R ′ values.…”

The present study harnesses fluorescence quenching between a nonfluorescent aniline and fluorophore 2-acetyl-3 H -benzo[ f ]chromen-3-one [2AHBC] in binary solvent mixtures of acetonitrile and 1,4-dioxane at room temperature and explores the fluorophore as an antimicrobial material. Our findings throw light on the key performance of organic molecules in the medicinal and pharmaceutical fields, which are considered as the most leading drives in therapeutic applications. In view of that, fluorescence quenching data have been interpreted by various quenching models. This demonstrates that the sphere of action holds very well in the present work and also confirms the presence of static quenching reactions. Additionally, the fluorophore was first investigated for druglike activity with the help of in silico tools, and then it was investigated for antimicrobial activity through bioinformatics tools, which has shown promising insights.

“…2 Due to the ease of structural modification based on BODIPY derivatives, it is possible to obtain luminophores that absorb and emit in almost the entire spectral range. 3 Such a set of practically significant physicochemical properties allows the use of dyes in this class in various fields, including molecular sensorics, 4,5 medical diagnostics, [6][7][8] biochemistry, [9][10][11][12] etc.…”

“…25,26 One of such methods suited particularly well for the treatment of electron detachment processes from the highest occupied orbitals where the single-particle picture of ionization still applies is the third order approximation scheme referred to as the outer-valence Green's function (OVGF) method. 26 Although the computational effort of the OVGF scheme is moderate (scaling as n 5 with respect to the number of molecular orbitals n), for larger coordination compounds of boron, computationally less demanding approaches like the density functional theory (DFT) analogue of the Koopmans theorem can be more preferable. 21,27 When modeling the excited states of boron chelate complexes, the time-dependent density functional theory (TD-DFT) was frequently used.…”

“…Previously, we have studied in organic solvents the properties of the BODIPY dye 1 with two bulky benzyl groups at the β, β΄-positions of the pyrrole rings [19] and BODIPY dimer 2 (Fig. 1) [46][47][48]. It was shown that the dye 1 has a high (about 100 %) quantum yield of fluorescence in solvents of different nature.…”

It is known that boron-dipyrromethene (BODIPY) dyes have a remarkable combination of photophysical and photochemical properties in solutions. Unfortunately, these properties are lost in thin films due to aggregation quenching effect (ACQ) and internal filter effect, limiting BODIPY application in optical devices. The introduction of bulky substituents into dye molecule should affect the supramolecular organization of BODIPY in thin films. Therefore, using the example of β-benzyl-substituted complex (1) and bis(BODIPY) dimer (2), we study the influence of bulky substituents at the β, β΄-positions of these BODIPY molecules on their aggregation behavior in mono-and multilayer Langmuir-Schaefer (LS) films. A comparative analysis of BODIPY spectral properties in LS and poly(methyl methacrylate) (PMMA) films has been carried out. It was shown that the presence of bulky benzyl-substituents in β-positions of pyrrole rings promotes the formation of H-and J-type aggregates in multilayer LS-films of the dye 1 and BODIPY dimer 2. The dye 1 predominantly forms H-type aggregates, while for the dye 2, the equilibrium is shifted towards the formation of J-type aggregates. The studied BODIPYs with a low content of up to 1 wt. % exhibit intense fluorescence being included in PMMA films. The results obtained give the possibility to use more efficiently thin-film structures based on the studied BODIPY thin films in optoelectronics.
