Chlorofullerenes featuring triple sequentially fused pentagons
The triple sequentially fused pentagons (TSFP) motif is one of the basic subunits that could be used for constructing fullerenes, but it violates the isolated pentagon rule (IPR) and has not been found in carb...

Synthesis, characterization, and investigations of some luminescent and catalytic properties of coordination polymers assembled from 5-(Pyridin-3-yl)isophthalic acid
The reactions of a semirigid carboxylic ligand 5-(Pyridin-3-yl)isophthalic acid(H2pyip) with Mn(CH3COO)2/Zn(NO3)2/Pb(NO3)2 afforded three new complexes: [Mn(pyip)(H2O)2]n(1), [Zn(pyip)(H2O)2]n(2), and [Pb(pyip)]n

A general asymmetric copper-catalysed Sonogashira C(sp3)–C(sp) coupling
Continued development of the Sonogashira coupling has made it a well established and versatile reaction for the straightforward formation of C–C bonds, forging the carbon skeletons of broadly useful functional...

A directive Ni catalyst overrides conventional site selectivity in pyridine C–H alkenylation
Achieving the transition metal-catalysed pyridine C3−H alkenylation, with pyridine as the limiting reagent, has remained a long-standing challenge. Previously, we disclosed that the use of strong coordinating ...

Mechanism-based ligand design for copper-catalysed enantioconvergent C(sp3)–C(sp) cross-coupling of tertiary electrophiles with alkynes
In contrast with the well-established enantioconvergent radical C(sp3)–C cross-coupling of racemic secondary alkyl electrophiles, the corresponding coupling of tertiary electrophiles to forge all-carbon quaternar...

Spatiotemporal and global profiling of DNA–protein interactions enables discovery of low-affinity transcription factors
Precise dissection of DNA–protein interactions is essential for elucidating the recognition basis, dynamics and gene regulation mechanism. However, global profiling of weak and dynamic DNA–protein interactions...

A fluorescent probe based on cyclochalcone for detecting peroxynitrite
A novel cyclic chalcone fluorescent probe C-PN was synthesized to detect ONOO−. After reaction with peroxynitrite, the double bond of C-PN in the cyclic chalcone structure was disconnected, which caused the chang...
