Four novel hetero-tetranuclear d-f coordination complexes, [Ln2Cd2(p-toluylate)10(phen)2] (Nd, 1; Pr, 2; Sm, 3) and [Ho2Cd2(p-chloro-benzoate)10(phen)2](4) (phen = 1, 10-phenanthroline), are synthesized by the hydrothermal method, and their structures are studied by single-crystal X-ray diffraction. Structures 1-3 are isomorphous and structure 4 has a similar molecular structure. In the near-infrared (NIR) region or in the visible region, complexes 1-4 show the characteristic emission bands of Ln(III) ions, which are attributed to the sensitization from the ligands and d-block (cadmium-ligand section) to f-block (lanthanide-ligand section). Moreover, in the Cd-Ln complexes, the CdLn separation is very close, so the d-orbital of the Cd(II) ion and the f-orbital of the Ln(III) ion may influence each other, which probably cause the intra-levels to be adjusted. This can have a significant effect on the emission bands in the NIR region, hence the corresponding emission bands of complexes 1, 2 and 4 exhibit shift or splitting compared with isolated Ln(III) ions. At the same time in the UV-Vis-NIR absorption spectra of the complexes, the corresponding absorption bands also show shift or splitting. The shift or splitting of bands in the NIR emission spectra and in the absorption spectra can evidence each other.

Background: Formation of a functional precursor B cell receptor (pre-BCR) is dependent on N-glycosylation of -heavy chains (HC). Results: Lack of core fucosylation of HC attenuated the interaction between HC and 5. Conclusion: Core fucosylation of HC mediates the assembly of pre-BCR. Significance: Learning how Fut8 regulates the assembly of pre-BCR is crucial for understanding pre-B cell development.

Hydrothermal reaction of the multidentate organic ligand (HTTHA) with indium chloride (InCl) produced a highly stable 3D luminescent indium-organic framework [In(OH)(HTTHA)(HO)] (1). Complex 1 exhibits remarkable luminescent properties, especially the multifunction sensitivity and selectivity for detecting Ru, UO; as well as small biomolecules thiamines (TPP, TMP, and TCl) based on a "turn-off" manner. In particular, the pyrophosphate groups of TPP and the phosphate groups of TMP could further affect the quenching rate, leading to different luminescent responds. In addition, we also discussed and proved the luminescence quenching mechanism in detail through comparative test and PXRD characterization. Therefore, complex 1 could be used as a kind of excellent luminescence sensor to detect Ru, UO, and thiamines (TPP, TMP, and TCl).

Six novel heterodinuclear d-f coordination complexes [LnCd(C 8 H 7 O 3 ) 5 (phen)(H 2 O)] (Ln = Sm 1, Eu 2, Tb 3, Nd 4, Ho 5, Er 6; C 8 H 7 O 3 = 4-methoxybenzoato; phen = 1,10-phenanthroline) were synthesized by the hydrothermal method, and their structures were studied by single-crystal X-ray diffraction. The IR and UV/Vis/NIR absorption spectra and the luminescence spectra of the six complexes were determined at room temperature. They have the same molecular structure, and two neighboring molecules are connected by hydrogen bonds or by a Ln···O weak interaction to form dimer crystals. In the visible region, the emission spectra of complexes 1-3 show the intense characteristic bands of the corresponding Ln III ions, which are mainly attributed to the ef-
