Rational design and synthesis of a new low molecular weight gelator (LMWG) having 9,10-diphenylanthracene core and terminal terpyridine is reported. Tb(III) and Eu(III) ion coordination to a LMWG results in green and pink emissive coordination polymer gels, respectively, with coiled nanofiber morphology. Further, control over stoichiometry of LMWG:Tb(III):Eu(III) leads to yellow and white light emitting bimetallic gels.

Regulating strategies for long persistent luminescence (LPL) are always in high demand. Herein, a series of coordination polymers (CPs) (SUST-Z1-Z4) are fabricated using 1,10-phenanthroline derivatives involving different substituents (─H, ─CH, ─Cl, and ─Br) as ligands, respectively. Crystallographic data demonstrate that these CPs adopt alternating arrangements of cadmium halide chains and π-conjugated ligands.

Copper-based nanoparticles have garnered significant interest in cancer therapy due to their ability to induce oxidative stress and cuproptosis in cancer cells. However, their antitumor effectiveness is constrained by the dynamic redox balance and the metabolic shift between oxidative phosphorylation and glycolysis. Here, a polydopamine-coated copper-α-ketoglutaric acid (α-KG) coordination polymer nanoparticle (CKPP) is designed for combined pyroptosis-cuproptosis cancer immunotherapy by amplifying reactive oxygen species (ROS) production and regulating cellular metabolism.

A new twofold interpenetrated 3D metal-organic framework (MOF), namely, poly[[μ-aqua-diaqua{μ-2,2'-[terephthaloylbis(azanediyl)]diacetato}barium(II)] dihydrate], {[Ba(CHNO)(HO)]·2HO}, (I), has been assembled through a combination of the reaction of 2,2'-[terephthaloylbis(azanediyl)]diacetic acid (TPBA, HL) with barium hydroxide and crystallization at low temperature. In the crystal structure of (I), the nine-coordinated Ba ions are bridged by two μ-aqua ligands and two carboxylate μ-O atoms to form a 1D loop-like Ba-O chain, which, together with the other two coordinated water molecules and μ-carboxylate groups, produces a rod-like secondary building unit (SBU). The resultant 1D polynuclear SBUs are further extended into a 3D MOF via the terephthalamide moiety of the ligand as a spacer.

Ln-MOFs, composed of lanthanide ions and functional organic ligands, are porous materials with tunable structures and unique luminescent properties. However, the interplay between ligand AIE properties and the framework's "antenna effect" on MOF morphology is understudied. Here, Tb-D-Cam-TPTB was synthesized via solvothermal method using TPTB (persulfurated arene) as the primary ligand, D-Cam as the auxiliary ligand, and Tb3+ as the metal ion.

We present a strategy for enhancing Li conduction in block copolymer electrolytes by introducing trace amounts of Li salts into polystyrene--poly(ethylene oxide) (PS--PEO), wherein Li ions preferentially coordinate with the -OH end groups of the PEO chains, resulting in the formation of double primitive cubic (3̅) structures. Compared with TFSI anions in Li salts, smaller anions (PF and BF) could facilitate ion localization more effectively, expanding the salt concentration range for developing stable 3̅ structures. The 3̅ structures formed in PS--PEOs doped with LiBF at = 0.
