近二十年来，由于其独特的光谱性质和相对于传统三配位化合物的优势，含有三价镧系离子（Ln 3+ ）的发光四配位化合物的研究大大增加。在这篇综述中，我们的目标是 Ln 3+四配位化合物 Q[Ln(L) 4 ]的合成、晶体结构和发光特性，作为具有各种配体的分子发光体（L：β-二酮酸盐、氨基膦酸盐、磺酰氨基膦酸盐、烷基二硫代氨基甲酸盐和羧酸盐）和不同的抗衡离子（Q +）。此外，我们描述了它们特殊的光物理特征以及镧系四配合物在分子设计中获得高效发光材料的潜力。还讨论了此类化合物的发光特性建模的结构数据和实验理论方法之间的关系。此外，我们还重点介绍了 Ln 3+四配位化合物作为高效发光材料的一些潜在应用。

Luminescence properties of lanthanide tetrakis complexes as molecular light emitters
Research on luminescent tetrakis coordination compounds containing trivalent lanthanide ions (Ln3+) has greatly increased in the last two decades owing to their unique spectroscopic properties and advantages over traditional tris compounds. In this review, we target the synthesis, crystal structure, and luminescence properties of Ln3+ tetrakis coordination compounds Q[Ln(L)4] as molecular light emitters with various classes of ligands (L: β-diketonates, carbacylamidophosphonates, sulfonylamidophosphonates, alkyldithiocarbamate and carboxylates) and different counterions (Q+). Moreover, we describe their special photophysical features and the potential of lanthanide tetrakis complexes in molecular design to obtain efficient luminescent materials. It is also discussed the relationship between structural data and experimental-theoretical approaches for the modeling of luminescence properties of this class of compounds. Additionally, we highlight some potential applications of Ln3+ tetrakis coordination compounds as efficient luminescent materials.
