Herein, we proposed a general strategy to design reversible photochromic mols. with solid-state fluorescence by introducing photoactive thienyl and benzothienyl groups into an AIE-active mol. skeleton. The combination of a thienyl or benzothienyl group and a triphenylethene in the right manner enabled the mols. to possess unique aggregation-induced emission properties and reversible photo-controlled changes in color and fluorescence in solid state. Theor. anal. revealed that photo-triggered cyclization and cycloreversion reactions were responsible for the reversible photochromism and photoinduced fluorescence switching, and the enlargement of the conjugation of the introduced photoactive units can significantly promote the cyclization reactions and the photochromic processes. The excellent performance of these photochromic mols. with aggregation-induced emission activity in a photoswitchable patterning paper and multiple encryption of anti-counterfeiting of a banknote demonstrated that they are perfectly suited for surface-involved photo-controlled applications such as information storage and data encryption.

Translation of new ¹⁸F-fluorination reactions to produce radiotracers for human positron emission tomog. (PET) imaging is rare because the chem. must useful scope and the process for ¹⁸F-labeled tracer production must be robust and simple to execute. The application of transition metal mediators has enabled impactful ¹⁸F-fluorination methods, but to date none of these reactions were applied to produce a human-injectable PET tracer. The authors present chem. and process innovations that culminate in the 1st production from [¹⁸F]fluoride of human doses of [¹⁸F]5-fluorouracil, a PET tracer for cancer imaging in humans. The 1st preparation of Ni σ-aryl complexes by transmetalation from arylboronic acids or esters was developed, and enabled the synthesis of the [¹⁸F]5-fluorouracil precursor. Routine production of >10 mCi doses of [¹⁸F]5-fluorouracil was accomplished with a new instrument for azeotrope-free [¹⁸F]fluoride concentration in a process that leverages the tolerance of H₂O in Ni-mediated ¹⁸F-fluorination.

And the article was included in JACS Au in 2021.Synthetic Route of C8H7BO2S This article mentions the following:

Under the shielding effect of nanomicelles, a sustainable micellar technol. for the design and convenient synthesis of ligand-free oxidizable ultrasmall Pd(0) nanoparticles (NPs) and their subsequent catalytic exploration for couplings of water-sensitive acid chlorides in water is reported. A proline-derived amphiphile, PS-750-M, plays a crucial role in stabilizing these NPs, preventing their aggregation and oxidation state changes. These NPs were characterized using ¹³C NMR (NMR), IR (IR), and surface-enhanced Raman scattering (SERS) spectroscopy to evaluate the carbonyl interactions of PS-750-M with Pd. High-resolution transmission electron microscopy (HRTEM) and energy-dispersive X-ray spectroscopy (EDX) studies were performed to reveal the morphol., particle size distribution, and chem. composition, whereas XPS measurements unveiled the oxidation state of the metal. In the cross-couplings of water-sensitive acid chlorides with boronic acids, the micelle’s shielding effect and boronic acids plays a vital role in preventing unwanted side reactions, including the hydrolysis of acid chlorides under basic pH. This approach is scalable and the applications are showcased in multigram scale reactions.
