“…Different strategies were developed to redshift the absorption of the sulfonium salts, and an efficient strategy was proposed by using fluorene as a π-conjugated spacer [288]. Fluorene is an excellent electron-donating group that was notably used for the design of chromophores for solar cells [289][290][291][292][293][294][295][296][297][298][299], light emitters for OLEDs [300][301][302][303][304][305][306] and charge transport materials for OFETs [307][308][309][310][311][312][313][314][315] and as fluorescent probes [316][317][318][319][320][321][322][323]. The fluorene scaffold was notably used by Yagci and coworkers to design thioxanthone exhibiting a high molar extinction coefficient and a redshifted absorption compared with PI-PAG [324].…”

During the last decades, multicomponent photoinitiating systems have been the focus of intense research efforts, especially for the design of visible light photoinitiating systems. Although highly reactive three-component and even four-component photoinitiating systems have been designed, the complexity to elaborate such mixtures has incited researchers to design monocomponent Type II photoinitiators. Using this approach, the photosensitizer and the radical/cation generator can be combined within a unique molecule, greatly simplifying the elaboration of the photocurable resins. In this field, sulfonium salts are remarkable photoinitiators but these structures lack absorption in the visible range. Over the years, various structural modifications have been carried out in order to redshift their absorptions in the visible region. In this work, an overview of the different sulfonium salts activable under visible light and reported to date is proposed.

“…To determine the photophysical properties of the compound synthesized for dye-sensitized solar cells (DSSC), different polarity solvents (THF, DMF, DCM, DMSO, and TOLUEN) were selected and used to measure the maximum absorption and emission wavelengths. In studies conducted with the Fluorene fluorophore, Wang and colleagues (Chen et al, 2022) observed bathochromic shifts in the emission spectra with increasing solvent polarity (TOLUEN < THF < EtOH < H 2 O). Compound number IV, which we synthesized, also contains both carbazole and fluorene groups, and it has been observed that bathochromic shifts occur with increasing solvent polarity.…”

Heterocyclic compounds containing nitrogen are regarded as essential structural motifs present in numerous natural products and organic materials. Within this group, carbazoles are important hetero-aromatic molecules which play a significant role in the development of materials with various functionalities. Carbazole derivatives play a crucial role in various organic electronic devices such as organic transistors (OTFTs), organic light-emitting diodes (OLEDs), and organic solar cells. In this study, the solubility of the carbazole nucleus, which initially had limited solubility in organic solvents, was increased by adding an octyl group. Next, a carbazole-based compound 3,6-di(fluorene-9)-9-octyl-9H-carbazole (IV) was synthesized via the Suzuki-Miyaura cross-coupling reaction (Figure 1). The photophysical and thermal properties of this compound were determined by UV-Vis, thermogravimetric analysis (TGA) and differential thermal analysis (DTA). The HOMO and LUMO energy levels and the optical band gap (E g ,opt) were obtained by cyclic voltammetry (CV) and absorption bands. TiO 2 -based dye-sensitized solar cells (DSSCs) were fabricated using compound IV. The photoelectrochemical properties of the resulting TiO 2 -DSSCs were measured.

Conducting polymers (CPs) are an innovative class of materials recognized for their high flexibility and biocompatibility, making them an ideal choice for health monitoring applications that require flexibility. They are active in their design. Advances in fabrication technology allow the incorporation of CPs at various levels, by combining diverse CPs monomers with metal particles, 2D materials, carbon nanomaterials, and copolymers through the process of polymerization and mixing. This method produces materials with unique physicochemical properties and is highly customizable. In particular, the development of CPs with expanded surface area and high conductivity has significantly improved the performance of the sensors, providing high sensitivity and flexibility and expanding the range of available options. However, due to the morphological diversity of new materials and thus the variety of characteristics that can be synthesized by combining CPs and other types of functionalities, choosing the right combination for a sensor application is difficult but becomes important. This review focuses on classifying the role of CP and highlights recent advances in sensor design, especially in the field of healthcare monitoring. It also synthesizes the sensing mechanisms and evaluates the performance of CPs on electrochemical surfaces and in the sensor design. Furthermore, the applications that can be revolutionized by CPs will be discussed in detail.
