Tridentate ligands are simple low-cost pincers, easy to synthetize, and able to guarantee stability to the derived complexes. On the other hand, due to its unique mix of structural and optical properties, zinc(II) ion is an excellent candidate to modulate the emission pattern as desired. The present work is an overview of selected articles about zinc(II) complexes showing a tuned fluorescence response with respect to their tridentate ligands. A classification of the tridentate pincers was carried out according to the binding donor atom groups, specifically nitrogen, oxygen, and sulfur donor atoms, and depending on the structure obtained upon coordination. Fluorescence properties of the ligands and the related complexes were compared and discussed both in solution and in the solid state, keeping an eye on possible applications.
三齿配体是简单、低成本的钳子，易于合成，并能保证衍生配合物的稳定性。另一方面，由于锌（II）离子独特的结构和光学性质混合，它是调节发射模式的理想候选物。本工作综述了一些关于锌（II）配合物的文章，这些配合物的荧光响应可以通过它们的三齿配体进行调节。根据配位后得到的结构，根据结合供体原子基团（具体为氮、氧和硫供体原子）对三齿钳子进行了分类。比较和讨论了配体和相关配合物在溶液和固态中的荧光性质，关注可能的应用。
