“…However, the wide scale development of organic devices is hampered by the fact that the formers are burdened by a relatively low efficiency, and generally by a lower stability compared to inorganic materials. Hence, an important research activity is constantly developed by many research groups in order to develop new materials to overcome the well-known efficiency and stability issues. − …”

Linear and nonlinear optical properties of a series of bis(E-dimesitylborylethenyl)-substituted arenes have been modeled by high-level computational protocols. The former compounds show a remarkable interest as infrared two-photon absorbers and hence may be used in the field of optical active and smart materials or for energy storage purposes. Excited state topologies, absorption and emission spectra, excited state metrics, natural transition orbitals and two-photon absorption cross-section of a series of chromophores have been computed by means of density functional theory (DFT) and timedependent DFT (TD-DFT). An extended benchmark test on the performance of different functionals had been performed. Dynamic and vibronic effects on absorption and emission spectra have been taken into account by sampling the conformational space by means of Wigner distribution and the former have been evidenced as rather important in order to recover absorption maxima and spectral band shape. Important infrared two photon absorption cross sections involving transitions to the second excited state have been observed. In particular, thiophene bridges have been evidenced as the most beneficial to increase TPA efficiency leading to cross-section exceeding 1000 GM.

“…This compound finds its application in organic solar cells as donor material having wide absorption characteristics. [38] Vincetti and co-workers synthesized benzofuran-2-carboxamides via microwave-assisted one pot protocol, the steps involed are shown in Scheme 6. They improved and standardized metal-free multicomponent microwave synthesis of title compounds by using commercially available raw materials such as 2-hydroxyacetophenones, benzonitrile, and benzaldehyde (48).…”

Out of the many heterocycles that exhibit pharmaceutical and therapeutic properties, benzofurans remain the most eye-catching to scientists ever since their discovery. From being present in natural products to synthetic analogs they show diverse biological properties which are used to treat various diseases. Interestingly, some of the benzofuran hybrids were docked against COVID-19 Main Protease and it showed appealing results. Apart from medicinal properties it also exhibits some non-drug applications. The structure activity relationship of benzofuran derivatives in many infections draws attention to the extent where drugs can be produced in a short time span which highlights their significance in medicinal chemistry. There are considerable reaction schemes to synthesize this moiety either simple one pot reactions or multistep. Here, we emphasize on the chemistry of benzofurans, synthesis and its derivatives in the recent years, some of which show notable anti-tumor, antifungal, anti-mycobacterial and anti-oxidant activities.

“…Qiu et al designed a small molecule ( SMTBF1 ) by utilizing 2‐ethylhexyloxy‐substituted TBF as the central donor block and ethylrhodanine as terminal ( Figure ). [ 278 ] Owing to the good stacking of TBF unit, SMTBF1 showed good phase separation and proper aggregation size in the blend films gave a very high FF of 0.72 and a promising PCE of 6.32%. In order to systematically investigate the effect of the central BDC derivatives on the photovoltaic performance of small molecules, Fan et al used BDT, TBF ( SMTBF2 ), or BDF as donor core and DPP as acceptor unit to construct three small molecule donors.…”

The state‐of‐the‐art bulk‐heterojunction (BHJ)‐type organic solar cells (OSCs) have exhibited power conversion efficiencies (PCEs) of exceeding 18%. Thereinto, thiophene and its fused‐ring derivatives play significant roles in facilitating the development of OSCs due to their excellent semiconducting natures. Furan as thiophene analogue, is a ubiquitous motif in naturally occurring organic compounds. Driven by the advantages of furan, such as less steric hindrance, good solubility, excellent stacking, strong rigidity and fluorescence, biomass derived fractions, more and more research groups focus on the furan‐based materials for using in OSCs in the past decade. To systematically understand the developments of furan‐based photovoltaic materials, the relationships between the molecular structures, optoelectronic properties, and photovoltaic performances for the furan‐based semiconductor materials including single furan, benzofuran, benzodifuran (BDF) (containing thienobenzofuran (TBF)), naphthodifurans (NDF), and polycyclic furan are summarized. Finally, the empirical regularities and perspectives of the development of this kind of new organic semiconductor materials are extracted.
