Pyridinium 1,4-zwitterionic thiolates were applied to a formal [3+2] annulation reaction with modified activated alkynes, affording various tetrasubstituted thiophenes with aryl, alkenyl, alkyl or silyl group at the special position. The structural modifi

Carbon dots (CDs) are novel fluorescent nanomaterials with good water solubility, high resistance to pho-tobleaching and low toxicity. While, there are few studies elaborate on the relationship among reaction conditions, properties and applications of CDs
A variety of nano-engineered photosensitizers have been developed for photodynamic therapy (PDT) of cancer diseases. However, traditional nano-engineering methods usually cannot avoid drug leak-age and premature release, and have disadvantages such as low
Carbon dots-peroxyoxalate micelle as a highly luminouschemiluminescence system under physiological c
Chemiluminescence (CL) has been widely used for bioanalysis owing to its high sensitivity, low back-ground and simplicity. However, most of the CL systems need acidic/alkaline conditions or organic sol-vent to enhance their luminescent efficiency, and the
Visualizing nitric oxide-dependent HIF-1 activity under hypoxia with a lipid droplet-targeting fluor
Evaluating the correlation between hypoxia inducible factor 1 (HIF-1) and nitric oxide (NO) generated under hypoxia is of great significance. In this work, we developed a fluorescent probe for the monitor of HIF-1 activity influenced by NO under hypoxia i
Transition-metal-switchable divergent synthesis of nitrile-containing pyrazolo[1,5-a]pyridines and i
Palladium-catalyzed oxidative formal [4 + 1] annulation of pyridine-substituted acrylonitriles toward di-vergent fused N-heterocycles synthesis is reported. The heterodifunctionalization reaction with Cu(OAc)2 and urea as the nitrogen source accesses to n
Oncolytic virus is an emerging anti-cancer strategy. However, extracellular matrix (ECM), as a physical barrier, limits virus spread within the tumor. To overcome the obstacle, we constructed a recombinant Newcastle disease virus (NDV) expressing matrix m
Photodynamic therapy (PDT) has emerged as a potential clinical strategy for tumor therapy. It can gener-ate reactive oxygen species (ROS) to cause the chemical damage of tumor cells and promote the immune killing effects of T cells on tumor cells in the p
Based on a recent report concerning endogenous agents (i.e., pyridoxal phosphate, adenosine triphosphate, adenosine monophosphate, folinic acid) that modulate the oligomerization of apopto-sis-associated speck-like protein (ASC) via the peptide epitope of
Selective coordination and localized polarization in graphene quantum dots: Detection of fluoride an
The development of ultra-sensitive methods for detecting anions is limited by their low charge to radius ratios, microenvironment sensitivity, and pH sensitivity. In this paper, a magnetic sensor is devised that exploits the controllable and selective coo
We report a facile and tailored method to prepare globally twisted chiral molecular cages through tun-able coordination of bis-bipyridine-terminated helicene ligands to a series of transition metals including Fe(II), Co(II), Ni(II) and Zn(II). This system
