The Cu‐glutathione (GSH) redox system, essential in biology, is designed here as a supramacromolecular assembly in which the tetrahedral 18e Cu(I) center loses a thiol ligand upon adsorption onto ZIF‐8, as shown by EXAFS and DFT calculation, to generate a very robust 16e planar trigonal single‐atom Cu(I) catalyst. Synergy between Cu(I) and ZIF‐8, r...

Biomass valorization is essential, particularly in emerging countries. Here, hydrochar from arabica coffee straw was functionalized with a triazole group (HD-TRz) for use as a support of palladium nanoparticles (PdNPs-HD-TRz) applied in the Ullmann coupling reaction for the first time. It provided remarkably excellent selectivities, conversions at...
Article
This mini-review highlights results on nanocatalysis involving various ferrocene-containing macromolecular supports (arene-cored and Pd-nanoparticle-cored dendrimers and dendronized polymers) obtained in our research group during the last 15 years. Nanocatalysis with Pd and Au nanoparticles stabilized by these metallomacromolecules have shown excel...
Article
Although dendrimer supports have been known as key parts of nanocatalysts, the capability of rigid dendrimers for this function has not yet been reported. Here, the study is focused on ferrocenylmethylenetriazolyl-terminated dendrimers (FcMTPD) as supports of remarkably efficient nanogold and nanopalladium catalysts. A biphasic system is elaborated...
Article
Production of hydrogen (H2) upon hydrolysis of inorganic hydrides potentially is a key step in green energy production. We find that visible-light irradiation of aqueous solutions of ammonia-borane (AB) or NaBH4 containing “click”-dendrimer-stabilized alloyed nanocatalysts composed of nanogold and another late transition-metal nanoparticle (LTMNP)...
Article
The level of apoptosis is directly related to the occurrence of cancer and other diseases. Real-time continuous monitoring of apoptotic process of living cells has great potential for early diagnosis of related diseases, as well as evaluation of therapeutic effect and screening of apoptotic drugs. This work proposed a ratiometric two-photon fluores...
Article
The Ullmann coupling reaction of aromatic halides is the most challenging C-C coupling reactions. Both MOF-based and MOF-derived types of catalysts have recently provided useful nanocatalysts for a variety of reactions, but they have rarely been compared. Here Ullmann-type aryl iodides homocoupling is efficiently catalyzed by gold and palladium nan...

Rh compounds including Rh nanoparticles (NPs) are among the most active catalysts for many reactions. Catalytically very reactive small Rh nanoparticles have been generated upon reduction of aqueous RhCl3 by cobaltocene, characterized, and shown to be very efficient for the test nitrophenol reduction (compared to other metal NPs), generation of hyd...
Article
Four stable 19-electron Fe and Co sandwich electron-reservoir and three hydride reservoir complexes reduce the prototypal nanocluster Au25(SR)18 (R = CH2CH2Ph) leading to a largely increased kinetic stabilization of the...
Article
A versatile two-photon fluorescent probe MCB for dual-detection of viscosity and SO2 derivatives in mitochondria with two cross-talk-free emissions (wavelength difference of 174 nm) has been rationally designed and synthesized. To our delight, probe MCB can not only recognize SO2 derivatives utilizing a blue fluorescence emission at 392 nm with a l...
Article
Two carbazole-based two-photon fluorescent lysotrackers with different electron-donating groups (methoxyl group for Lyso-MCO and dimethylamino group for Lyso-NCO, respectively) have been developed from simple starting materials via an only 2-step procedure. Both of them exhibit pH-independent and specific lysosomes location with rapid staining rate...
Article
Strategic modifications from N-containing through O-containing to S-containing Schiff-base receptors lead to the development of a highly selective Au³⁺ two-photon fluorescent probe that responded via an Au³⁺-induced hydrolysis mechanism. Here, we systematically demonstrate the two-step process of Au³⁺-induced hydrolysis reaction by implementing a s...

Mitochondria and lysosomes are essential cellular organelles in most eukaryotic cells by playing the physiological roles to support the normal functions of cells, as well as the life of the whole body. To date, small-molecule fluorescent probes have been considered as one of the vital tools for monitoring and visualizing multiple biological analyte...
Article
A highly selective two-photon fluorescent probe (PyCM-1) for Au3 + was developed with distinct “turn on” fluorescence response, low detection limit (22 nM) and large two-photon absorption cross-sections (696 GM at 860 nm). Its high selectivity for Au3 + over Au⁺ was achieved via the modification on the type of coordination atoms in the Schiff base...

A practical heterobimetallic lanthanide‐catalyzed transamidation of primary, secondary and tertiary amides with aliphatic and aromatic amines has been developed. The methodology was also applied to the weakly reactive thioamides to demonstrate its versatility and wide substrate scope. The heterobimetallic lanthanide catalysts showed high catalytic...
Article
Two colorimetric and two-photon fluorescent probes (PCB and MPCB) for SO2 derivatives were designed and synthesized with rapid response, high selectivity, low detection limits, and large Stokes shifts. The probes displayed “turn on” fluorescence response to SO2 derivatives probably due to the nucleophilic addition to the electron-poor C[double bond...
Article
We develop a novel coumarin-alkyne derivative (NC7-AL), which can specifically react with Au3+ and give a colorimetric and fluorescent “turn-on” response towards Au3+. Notably, other alkynophilic metal species such as Au+, Ag+, Pd2+, Ni2+, Cu2+, and Hg2+ do not produce an interfering signal. A good linear relationship between emission intensity at...
