“…It is well known that boron-containing fluorescent complexes, such as derivatives of boron dipyrromethene (BODIPY), dibenzoylmethanatoboron difluoride (DBMBF 2 ) and others, possess impressive photophysical/photochemical properties and are promising objects in the development of new fluorescent materials for organic electronics and photonics [ 23 , 24 , 25 ]. These fluorophores can find application as optical [ 26 , 27 ], mechanochromic [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ], or photochromic [ 37 , 38 ] materials, as well as sensors for the detection of oxygen [ 39 ], amines [ 40 ], and aromatic compounds [ 41 , 42 , 43 ]. Incorporation of these complexes into the polymer matrix with the next study of properties is a current trend in polymer chemistry and materials science [ 44 , 45 ].…”

A method for the preparation of polydimethylsiloxanes with grafted methoxy-substituted dibenzoylmethanatoboron difluoride has been described. The structures of prepared polymers were confirmed using NMR, IR spectroscopy and gel permeation chromatography methods. Their thermal properties were investigated using thermal gravimetric analysis, differential scanning calorimetry and thermomechanical analysis. The prepared polymers had good thermal (Td5% up to 393 °C) and thermo-oxidative (Td5% = 413 °C) stability. The polymers started to transit in a viscous flow state at about 40 °C (for 3 a) and at about 20 °C (for 3 b). The viscoelastic characteristics of prepared polymers were determined in the sinusoidal oscillating vibrations mode. It was shown that the studied polymers at low frequencies at room temperature are viscoelastic fluids (G′ < G″). Increasing the frequency led to inversion (crossover) of dependences G′ and G″, which indicated the transition of polymers from viscous to elastomeric behavior characteristics, and the beginning of the formation of a physical network. Optical properties were studied using electron absorption, steady-state and time-resolved fluorescence spectroscopy. It was shown that intramolecular H-dimers exist in the ground state. The polymers studied had a bright fluorescence in the solution and in the solid state, consisting of bands of monomer and excimer emission. Thermally-activated delayed fluorescence was observed in the solution and the solid state. The prepared polymers possess intriguing properties that make them useful as optical materials, sensors or imaging agents.

“…Some IR studies have been recently addressed to the detection of sub-ppm concentrations of benzene, with experimental detection limits of 0.26 and 0.41 ppm for benzene and toluene (using a 100 m path length for these two gases at atmospheric pressure) [13]. Moreover, some colorimetric assays have been developed by using sensitive materials [14] and a simple fluorescent sensor [15] has also been developed utilizing a material based on dibenzoylmethanatoboron difluoride (DBMBF2), a fluorophore which is capable of forming exciplexes with benzene, toluene, and xylenes (BTX). Upon calibration, the fluorescent sensor provides simultaneous quantification of benzene, toluene, and p-xylene in three-component mixtures [15].…”

The presence of benzene and similar aromatic compounds in civil environments is due to anthropic actions but also to natural sources. Natural gas consists of a gas mixture where benzene and related compounds are usually presents. Thus, the detection of these compounds in natural gas pipelines is of the utmost importance as well as the control of the concentration level, which must remain below the limits consented by law. In this regard, it is of striking interest to engineer devices able to detect these compounds by automatic and continuous remote control. Here, we discuss the application of an optical device designed for the measurement of sulfured odorizing agents in natural gas pipelines aiming at the detection and the measurement of benzene, toluene, and xylenes (BTX) in the same contexts. The instrument consists of a customized UV spectrophotometer connected to an automatic control system able to provide in-field detections of BTX through a continuous and remote check of the gaseous mixture. Relatively to benzene, the instrument is characterized by values of LOD (level of detection) and LOQ (level of quantification) equal to 0.55 and 1.84 mg/Sm3, respectively. Similar limits are found for toluene and xylenes (LOD of 0.81, 1.05, 1.41, and 1.00 mg/Sm3 for toluene, meta-, ortho-, and para-xylene, respectively).
