Abstract
Recently developed dynamic nuclear polarization (DNP) technology offers the potential of increasing the NMR sensitivity of even rare nuclei for biological imaging applications. Hyperpolarized 89 Y is an ideal candidate because of its narrow NMR linewidth, favorable spin quantum number (I=1/2 ), and long longitudinal relaxation times (T1 ). Strong NMR signals were detected in hyperpolarized 89 Y samples of a variety of yttrium complexes. A dataset of 89 Y NMR data composed of 23 complexes with polyaminocarboxylate ligands was obtained using hyperpolarized 89 Y measurements or 1 H,89 Y-HMQC spectroscopy. These data were used to derive an empirical equation that describes the correlation between the 89 Y chemical shift and the chemical structure of the complexes. This empirical correlation serves as a guide for the design of 89 Y sensors. Relativistic (DKH2) DFT calculations were found to predict the experimental 89 Y chemical shifts to a rather good accuracy.

Abstract
A novel two-dimensional (2D) mononuclear complex, namely, (enH(2))[Tb(III)(egta)(H(2)O)](2)·6H(2)O (H(4)egta=ethyleneglycol-bis-(2-aminoethylether)-N,N,N',N'-tetraacetic acid and en=ethylenediamine), was successfully synthesized and characterized by infrared spectrum, UV-vis spectrum, fluorescence spectrum, thermal analysis and single-crystal X-ray diffraction techniques. Single-crystal X-ray diffraction analysis reveals that the central Tb(III) ion is nine-coordinate in geometry of pseudo-monocapped square antiprismatic polyhedron. Furthermore, the hydrogen bonds play an important role in the fabrication of layer structure of the complex. Through hydrogen bonds between ethylenediamine cation (enH(2)(2+)) and [Tb(III)(egta)(H(2)O)](-) complex anion, the title complex forms a 2D layer network along [111] crystallographic direction. Particularly, the fluorescent property is also fully investigated, which indicates that the title complex would be a potential candidate as fluorescent materials.
