From synthesis to applications of biomolecule-protected luminescent gold nanoclusters.

Gold nanoclusters (AuNCs) are a class of novel luminescent nanomaterials that exhibit unique properties of ultra-small size, featuring strong anti-photo-bleaching ability, substantial Stokes shift, good biocompatibility, and low toxicity. Various biomolecules have been developed as templates or ligands to protect AuNCs with enhanced stability and luminescent properties for biomedical applications. In this review, the synthesis of AuNCs based on biomolecules including amino acids, peptides, proteins and DNA are summarized.

Bimetallic Coordination Polymers: Synthesis and Applications in Biosensing and Biomedicine.

Bimetallic coordination polymers (CPs) have two different metal ions as connecting nodes in their polymer structure. The synthesis methods of bimetallic CPs are mainly categorized into the one-pot method and post-synthesis modifications according to various needs. Compared with monometallic CPs, bimetallic CPs have synergistic effects and excellent properties, such as higher gas adsorption rate, more efficient catalytic properties, stronger luminescent properties, and more stable loading platforms, which have been widely applied in the fields of gas adsorption, catalysis, energy storage as well as conversion, and biosensing.

An Ir(III) cyclometalate-functionalized molecularly imprinted polymer: photophysics, photochemistry and chemosensory applications.

A luminescent trimethylamine (TMA) sensor, PTMA-Ir, has been designed and synthesized through immobilizing a phosphorescent iridium(III) complex on a TMA-imprinted polymer. Detailed study shows that the quenching of phosphorescence of PTMA-Ir can serve as a reporter for the binding of TMA on the imprinting sites, thus providing a sensitive, selective, and rapid detection of TMA in both aqueous solutions and gaseous states. Loading PTMA-Ir on filter paper produced a deposition T-Ir, the phosphorescence of which is quenched within 5 s upon exposure to TMA vapor with detection limits of 9.

Photoredox Catalysis for the Fabrication of Water-Repellent Surfaces with Application for Oil/Water Separation.

Silanization processes with perfluoroalkyl silanes have been demonstrated to be effective in developing advanced materials with many functional properties, including hydrophobicity, water repellency, and self-cleaning properties. However, practical industrial applications of perfluoroalkyl silanes are limited by their extremely high cost. On the basis of our recent work on photoredox catalysis for amidation with perfluoroalkyl iodides, its application for surface chemical modification on filter paper, as an illustrative example, has been developed and evaluated.

Visible light photocatalytic cross-coupling and addition reactions of arylalkynes with perfluoroalkyl iodides.

Visible light photocatalytic cross-coupling and addition reactions of arylalkynes with perfluoroalkyl iodides have been developed. Through slight modifications of the reaction conditions, reactions that are selective for the preparation of the C-C coupling product (perfluoroalkyl alkynes) and the addition products (iodo-perfluoroalkyl substituted alkenes) can be achieved. These reactions work well with different types of alkynes and perfluoroalkyl iodides.

Electronic Communication in Luminescent Dicyanorhenate-Bridged Homotrinuclear Rhenium(I) Complexes.

A series of cyano-bridged homotrinuclear Re(I) complexes with the general formula of {[Re]'[Re][Re]'} {[Re]' = -[Re(CO)(LL)(X)]; [Re] = -[(NC)Re(CO)(phen)(CN)]-; LL = diimine, diphosphine, or two carbonyl ligands; X = triphenylphosphine or carbonyl ligand} and the corresponding mononuclear complex analogues were synthesized. The structures of most of the trinuclear Re(I) complexes have been determined by X-ray crystallography. The relative orientations of peripheral to central Re(I) units in these structures vary considerably.

[1,3-Bis(diphenyl-phosphan-yl)propane-κP,P'](1,10-phenanthroline-κN,N')copper(I) perchlorate.

The title compound, [Cu(C(12)H(8)N(2))(C(27)H(26)P(2))]ClO(4), crystallizes with two Cu(I) complex cations and two perchlorate anions in the asymmetric unit. Each Cu(I) cation is four-coordinated by two P atoms of a 1,3-bis-(diphenyl-phosphan-yl)propane mol-ecule and two N atoms of a 1,10-phenanthroline ligand, with a coordination geometry that can be considered as distorted tetra-hedral. The crystal studied was twinned with a twin ratio of 0.

[μ-1,2-Bis(diphenyl-phosphino)ethane-κP:P']bis-{[1,2-bis-(diphenyl-phosphino)ethane-κP,P']cyanidocopper(I)} methanol disolvate.

The title centrosymmetric complex, [Cu(2)(CN)(2)(C(26)H(24)P(2))(3)]·2CH(3)OH, consists of two five-membered [Cu(dppe)CN] rings [dppe is 1,2-bis-(diphenyl-phosphino)ethane] bridged by one μ(2)-dppe ligand, and two methanol solvent mol-ecules. The angles around the central metal atom indicate that each Cu(I) atom is located in the center of a distorted tetra-hedron. The coordination sphere of each Cu(I) atom is formed by three P atoms from two dppe ligands, and one C atom from the cyanide ligand.
