Abstract The inner mitochondrial membrane (IMM) generates power to drive cell function, and its dynamics control health cellular homeostasis. Here, we describe the cell-permeant, lipid-like small molecule MAO-N 3 use it assemble high-density environmentally sensitive (HIDE) probes that selectively label image IMM in live cells multiple states. pairs with strain-promoted azide–alkyne click chemistry-reactive fluorophores support HIDE imaging using confocal, structured illumination,...
Herein we report an atom- and step-economic aromatic cyanoalkylation reaction that employs nitriles as building blocks proceeds through Csp2–H Csp3–H bond activation steps mediated by NiIII. In addition to cyanomethylation with MeCN, regioselective α-cyanoalkylation was observed various nitrile substrates generate secondary tertiary nitriles. Importantly, the best of our knowledge these are first examples C–H reactions occurring at a NiIII center, which may exhibit different reactivity...
New bright, photostable, emission-orthogonal fluorophores that blink without toxic additives are needed to enable multicolor, live-cell, single-molecule localization microscopy (SMLM). Here we report the design, synthesis, and biological evaluation of Yale676sb, a near-IR-emitting fluorophore achieves these goals in context an exceptional quantum yield (0.59). When used alongside HMSiR, Yale676sb enables simultaneous, two-color SMLM two intracellular organelles (ER + mitochondria) with only...
A nickel/photoredox, dual-catalyzed amidation reaction between alkylsilicate reagents and alkyl/aryl isocyanates is reported. In contrast to the previously reported reductive coupling process, this protocol characterized by mild conditions absence of a stoichiometric reductant. mechanistic hypothesis involving nickel-isocyanate adduct proposed based on literature precedent further validation experimental results.
A series of water soluble octa-functionalized POSSs were facilely synthesized via thiol-ene and Menschutkin click chemistry. Among them, octa-alkynyl POSS further reacted with azide-terminal alkyl long chains, resulting in a well-defined, amphiphilic octopus-like POSS. For the first time it was used for host-guest encapsulation exhibited an ultrahigh loading capability.
Minisci-type alkylation of electron-deficient heteroarenes has been a pivotal technique for medicinal chemists in the synthesis drug-like molecules. However, such transformations usually require harsh conditions (e.g., strong acids, stoichiometric amount oxidants, elevated temperatures, etc.). Herein, by utilizing photoredox catalysis, highly-selective method using heteroaryl sulfones developed that can be carried out under acid-free and redox-neutral conditions. Because these mild...
The selective 1,2-aminoacylation of olefins provides opportunities for the rapid construction nitrogen-containing molecules.
Achieving uniform Li deposition is vital for the construction of a safe but also efficient Li-metal anode batteries (LMBs). Herein, facile coating strategy used forming an ultra-thin aramid nanofiber (ANF) membrane, with network structure, on (ANF-Li) as artificial layer inhibiting dendrite's growth. The results show that under ultra-high current density 50 mA cm-2 , ANF-Li|ANF-Li symmetric cells can be kept stably cycled period exceeding 300 h. ANF-Li|LiFePO4 full exhibit high-capacity...

A radical-mediated functionalization of allyl alcohol derived partners with a variety alkyl 1,4-dihydropyridines via photoredox/nickel dual catalysis is described. This transformation transpires high linear and E-selectivity, avoiding the requirement harsh conditions (e.g., strong base, elevated temperature). Additionally, using aryl sulfinate salts as radical precursors, sulfones can also be obtained. Kinetic isotope effect experiments implicated oxidative addition nickel catalyst to...
Abstract Proteins and polypeptides containing extended backbone monomers embody highly desirable structures functions, but they cannot yet be biosynthesized in cells. There are two challenges at work. First is the ribosome, whose ability to promote rapid bond-forming reactions from anything other than an α-amino acid or α-hydroxy unknown. The second challenge absence of orthogonal enzymes that acylate tRNA with monomers. Here we describe a general approach programmed cellular synthesis...

Lysosomes have long been known for their acidic lumens and efficient degradation of cellular byproducts. In recent years, it has become clear that function is far more sophisticated, involving multiple cell signaling pathways interactions with other organelles. Unfortunately, interior, fast dynamics, small size make lysosomes difficult to image fluorescence microscopy. Here we report a far-red molecule, HMSiR680-Me, fluoresces only under conditions, causing selective labeling organelles in...
