“…The existence of fluorescent reagents is a requirement for the development of analytical techniques. [ 15 ] In theory, confining a large number of fluorophores in a limited container can result in localized high fluorescence concentrations. [ 16 ] Traditional organic fluorescent polymers, conversely, have unstable characteristics and are challenging to use in practical applications.…”

In recent years, fluorescent organic–inorganic hybrid nanomaterials have received much interest as potential fluorescent sensor materials. In this study, fluorescent organic–inorganic hybrid nanomaterials (POSS@ANT) were created using polyhedral oligomeric silsesquioxane as the precursor and 9,10‐bromoanthracene as the monomer. The morphology and composition of POSS@ANT, as well as its pore characteristics and fluorescence properties were studied. POSS@ANT displayed steady fluorescence emission at an excitation wavelength of 374 nm. Next, a β‐carotene fluorescence sensor was developed using the capacity of β‐carotene to quench the fluorescence of POSS@ANT. The quenching process is linked to acceptor electron transfer and energy transfer, and the sensor has a high selectivity for β‐carotene. This β‐carotene fluorescence analysis method that we established has a linear range of 0.2–4.3 mg/L and a detection limit of 0.081 mg/L. Finally, it was used to quantify β‐carotene in health products, the recovery rate was 91.1–109.9%, the relative standard deviation (RSD) was 2.2–4.3%, and the results were comparable with the results of high‐performance liquid chromatography. The approach is reliable and can be used to determine β‐carotene in health products.

“…While the inorganic components function as semiconductors, the organic cations serve as a physical and electronic barrier. These hybrid materials could be used to improve charge carrier mobility and facilitate charge/energy transfer in high-efficiency optoelectronic and photonic devices such as solar cells, photodetection, and light-emitting diodes [16][17][18]. The templating effect of cations is a major factor that causes the formation of various inorganic networks.…”

This study explores the electronic properties of (C2H7N4O)2BiCl5 using the density functional theory (DFT) method, which was compared with the experimental data. The band structure of the compound indicated that it is a direct semiconductor with a band gap energy of 3.54 eV, which was comparable with the value (3.20 eV) obtained experimentally from the UV–vis spectroscopy. The density of state study showed that the conduction band was formed mainly by Bi 6p, C 2p, and N 2p states, while the valence band was formed mainly by Cl 2p, O 2p, and N 2p states. Hirshfeld surface analysis and enrichment ratio (E) were further used to investigate and quantify the intermolecular interactions within the compound. These studies established that the most important role in the stability of the structure of this crystalline material was provided by hydrogen bonding and π–π stacking interactions. The crystalline morphology of the compound was determined using BFDH simulation, based on the single-crystal structure result. Furthermore, Fourier transform infrared spectroscopy (FTIR) was used to study the vibrational modes of carbamoyl-ganidinium cations. The charge transfer process within the anionic chains of [BiCl5]∝, studied using photoluminescence spectroscopy, resulted in a broad emission band with two positions of maxima centered at 336 and 358 nm. This work offers a good understanding of the optical, structural, as well as the electrical properties of (C2H7N4O)2BiCl5, which are necessary in its applications in areas such as multifunctional magnetic, optoelectronic, and photonic systems.

“…Low dimensional (1D and 0D) substructures expand physical properties associated with organic and inorganic constituents. The anionic parts act as semiconductors and the organic cations act as potential barriers, contributing to original electronic and optical behavior [ 16 , 17 , 18 ]. Thus, in order to increase the dimensionality of the inorganic substructures and decrease the band gap, an additional successful scheme is the incorporation of multifunctional organic cations capable of influencing the bonding structures within the inorganic network and increasing the orbital interaction across adjacent chains.…”

The new organic–inorganic compound (C6H9N2)2BiCl5 (I) has been grown by the solvent evaporation method. The one-dimensional (1D) structure of the allylimidazolium chlorobismuthate (I) has been determined by single crystal X-ray diffraction. It crystallizes in the centrosymmetric space group C2/c and consists of 1-allylimidazolium cations and (1D) chains of the anion BiCl52−, built up of corner-sharing [BiCl63−] octahedra which are interconnected by means of hydrogen bonding contacts N/C–H⋯Cl. The intermolecular interactions were quantified using Hirshfeld surface analysis and the enrichment ratio established that the most important role in the stability of the crystal structure was provided by hydrogen bonding and H···H interactions. The highest value of E was calculated for the contact N…C (6.87) followed by C…C (2.85) and Bi…Cl (2.43). These contacts were favored and made the main contribution to the crystal packing. The vibrational modes were identified and assigned by infrared and Raman spectroscopy. The optical band gap (Eg = 3.26 eV) was calculated from the diffuse reflectance spectrum and showed that we can consider the material as a semiconductor. The density functional theory (DFT) has been used to determine the calculated gap, which was about 3.73 eV, and to explain the electronic structure of the title compound, its optical properties, and the stability of the organic part by the calculation of HOMO and LUMO energy and the Fukui indices.
