This paper highlights advances made using the 4-bora-3a,4a-diaza-s-indacene (BODIPY) as a fluorophore in design and application of fluorescent sensors for microenvironment polarity. Sections of the paper cover broad analysis of a range of fluorescent indicators immobilized in ethyl-and methyl cellulose matrices. The present study demonstrates that BODIPYbased fluorescent materials could be successfully utilized for ratiometric detection of ethanol and acetone in gas phase. The achieved limit of detection value equals 0.02 mg/ml for acetone and 0.08 mg/ml for ethanol, whereas obtained sensoric materials are reusable without regeneration required.

“…There are many polar substituents that contribute to the formation of dipole interactions with the corresponding substrates. Such matrices include: among the organic ones most popular are oligo-polysaccharides [ 46 , 47 ], cellulose [ 48 , 49 , 50 , 51 ], polymethylmethacrylate (PMMA) [ 52 , 53 , 54 , 55 ], polyvinyl chloride (PVC) [ 11 , 56 ]; among inorganic ones most popular are silica and other polymeric oxides obtained by sol-gel synthesis [ 57 , 58 , 59 , 60 , 61 , 62 ]. On the other hand, the luminophore must have the following groups (one or several): H-, hydroxo-, amino-, nitro-, sulpho-, mercapto- and groups comprising from atoms with an unsplit electron pair and capable of forming a donor-acceptor bond; phenyl and other cyclically conjugated molecules to form π-π stacking.…”

“…And depending on the choice of matrix, the nature of the sensor response may vary or not appear at all [ 61 ]. PMMA matrices with BODIPY can be used to produce sensors for polarity reversal of the environment [ 62 ]. Ethyl cellulose matrices with BODIPY or bis-dipyrrin complexes can be used for the some gases detection in micro quantities in air [ 48 , 49 , 63 ].…”

On the Use of Polymer-Based Composites for the Creation of Optical Sensors: A Review

2022

View full text Add to dashboard Cite

Polymers are widely used in many areas, but often their individual properties are not sufficient for use in certain applications. One of the solutions is the creation of polymer-based composites and nanocomposites. In such materials, in order to improve their properties, nanoscale particles (at least in one dimension) are dispersed in the polymer matrix. These properties include increased mechanical strength and durability, the ability to create a developed inner surface, adjustable thermal and electrical conductivity, and many others. The materials created can have a wide range of applications, such as biomimetic materials and technologies, smart materials, renewable energy sources, packaging, etc. This article reviews the usage of composites as a matrix for the optical sensors and biosensors. It highlights several methods that have been used to enhance performance and properties by optimizing the filler. It shows the main methods of combining indicator dyes with the material of the sensor matrix. Furthermore, the role of co-fillers or a hybrid filler in a polymer composite system is discussed, revealing the great potential and prospect of such matrixes in the field of fine properties tuning for advanced applications.

“…As the potential energy surface (PES) might have a large number of local minima, the study of the conformational multiformity of polyatomic molecules is often a difficult task [ 15 , 16 ]. At the same time, understanding the features of the molecular structure and the possibilities of low-energy doped changes, caused by light absorption and associative processes, can play a key role in the prediction of the mechanisms of directional changes in the optical properties of compounds for fine tuning and application in molecular sensorics [ 17 , 18 ].…”

Quantum Chemical Study Aimed at Modeling Efficient Aza-BODIPY NIR Dyes: Molecular and Electronic Structure, Absorption, and Emission Spectra

et al. 2020

View full text Add to dashboard Cite

A comprehensive study of the molecular structure of aza-BODIPY and its derivatives, obtained by introduction of one or more substituents, was carried out. We considered the changes in the characteristics of the electronic and geometric structure of the unsubstituted aza-BODIPY introducing the following substituents into the dipyrrin core; phenyl, 2-thiophenyl, 2-furanyl, 3-pyridinyl, 4-pyridinyl, 2-pyridinyl, and ethyl groups. The ground-state geometries of the unsubstituted Aza-BODIPY and 27 derivatives were computed at the PBE/6-31G(d) and CAM-B3LYP/6-31+G(d,p) levels of theory. The time-dependent density-functional theory (TDDFT) together with FC vibronic couplings was used to investigate their absorption and emission spectra.
