Int J Mol Sci 2023; 24:1217. [PMID: 36674731 PMCID: PMC9860957 DOI: 10.3390/ijms24021217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 12/21/2022] [Accepted: 12/28/2022] [Indexed: 01/11/2023] Open
Abstract
This research work is devoted to collecting a high-quality dataset of BODIPYs in a series of 10-30 solvents. In total, 115 individual compounds in 71 solvents are represented by 1698 arrays of the spectral and photophysical properties of the fluorophore. Each dye for a series of solvents is characterized by a calculated value of solvatochromic sensitivity according to a semiempirical approach applied to a series of solvents. The whole dataset is classified into 6 and 24 clusters of solvatochromic sensitivity, from high negative to high positive solvatochromism. The results of the analysis are visualized by the polarity mapping plots depicting, in terms of wavenumbers, the absorption versus emission, stokes shift versus - (absorption maxima + emission maxima), and quantum yield versus stokes shift. An analysis of the clusters combining several dyes in an individual series of solvents shows that dyes of a high solvatochromic sensitivity demonstrate regular behaviour of the corresponding plots suitable for polarity and viscosity mapping. The fluorophores collected in this study represent a high quality dataset of pattern dyes for analytical and bioanalytical applications. The developed tools could be applied for the analysis of the applicability domain of the fluorescent sensors.

Abstract
Boron-dipyrromethene derivatives (BODIPYs) are a category of molecules with excellent photophysical properties and can be applied to various fields. This work investigates the fluorescent properties of two azomethine-BODIPY dyads in different solvents based on the time-dependent density functional theory (TD-DFT) method. The potential energy curves (PECs) show that the polar protic solvent and the enhanced π-conjugation effect can lower the proton-transfer (PT) barriers, causing the main configuration of NA-BODIPY in methanol to be the keto form, while the main configuration of NA-BODIPY in toluene and SA-BODIPY in methanol and toluene is the enol form. The keto forms of the two compounds possess the twisted intramolecular charge transfer (TICT) decay pathway in the excited state identified by the optimized twisted configurations and the appropriate barriers of the TICT process, whereas the twisted configurations of the enol forms are nonexistent. TICT successfully competes with excited-state proton transfer (ESIPT) of the keto form, which leads to the fluorescence quenching of NA-BODIPY in methanol. This work provides new ideas for the influence of enol-keto tautomerism and the competitiveness of TICT and ESIPT on the photophysical properties of BODIPYs and is expected to provide guidance for the design of new BODIPY functional molecules.

Abstract
A simple semiempiric phenomenological approach is developed for quantifying the solvent effect on the absorption and emission properties of BODIPYs. It is based on a new rule describing the linear relationship between the difference (Stokes shift) and the sum (double Gibbs free energy of electron transfer) for absorption and emission wavenumbers derived from a combination of solvent functions of Liptay theory. This rule is correspondent to changes of dipole moments in the ground and excited states. High reliability and advantages of the developed approach in comparison with traditional methods of the analysis of the solvatochromism based on Dimroth-Reichard and Lippert-Mataga solvent scales are illustrated for selected BODIPYs exhibiting positive, negative, and near-zero solvatochromism.

Abstract
A review of intramolecular hydrogen bonding in ortho-hydroxyaryl Schiff bases, ortho-hydroxyaryl Mannich bases, dipyrrins, ortho-hydroxyaryl ketones, ortho-hydroxyaryl amides, and 4-Bora-3a,4a-diaza-s-indacene (BODIPY) dyes with tautomeric sensors as substituents is presented in this paper. Ortho-hydroxy Schiff and Mannich base derivatives are known as model molecules for analysing the properties of intramolecular hydrogen bonding. The compounds under discussion possess physicochemical features modulated by the presence of strong intramolecular hydrogen bonds. The equilibrium between intra- and inter-molecular hydrogen bonds in BODIPY is discussed. Therefore, the summary can serve as a knowledge compendium of the influence of the hydrogen bond on the molecular properties of aromatic compounds.
