A new class of highly potentNS5Ainhibitors with an unsymmetric benzimidazole-difluorofluorene-imidazole core and distal [2.2.1]azabicyclic ring system was discovered. Optimization of antiviral potency and pharmacokinetics led to the identification of 39 (ledipasvir, GS-5885). Compound 39 (GT1a replicon EC50 = 31 pM) has an extended plasma half-life of 37–45 h in healthy volunteers and produces a

Triphenylethylenyl-based donor–acceptor–donor molecules: studies on structural and optical properties and AIE properties for cyanide detection
Six novel molecules with donor–acceptor–donor (D–A–D) configurations were synthesized with a middle acceptor flanked by two electron-rich triphenylthylenyl moieties. The first set of three molecules (TPE-FLN, TPE-AQN and TPE-BZQ) consists of fluorenone, anthraquinone and benzophenone as acceptors, respectively, which then underwent Knoevenagel condensation with malononitrile to give the second set

A fluorenone based alternating copolymer (PFN-DPPF) with a furan based fused aromatic moiety has been designed and synthesized. PFN-DPPF exhibits a small band gap with a lower HOMO value. Testing this polymer semiconductor as the active layer in organic thin-film transistors results in hole mobilities as high as 0.15 cm2 V−1 s−1 in air.
Effect of Arylmethylene Substitutions on Molecular Structure, Optoelectronic Properties and Photovoltaic Performance of Dithienocyclopentafluorene‐Based Small‐Molecule Acceptors
methylene-functionalized conjugated side chains have been developed to systemically investigate the impact of arylmethylene substitution and its number on molecularstructure, optoelectronic properties and photovoltaic performance. Better light-harvesting properties and molecular planarity, lower bandgaps and higher LUMO levels are achieved, enabling improvements in device efficiency both for halogenated
