Abstract:
Over the past two decades, triphenylamine (TPA)-based supramolecular coordination metallacycles, constructed by incorporating TPA and its derivatives as key building blocks into two-dimensional (2D) coordination-driven assemblies, have gradually received considerable attention and emerged as an important research topic within the field of discrete supramolecular coordination complexes (SCCs). Leveraging the synthetic accessibility and outstanding optoelectronic properties of TPA units, the resulting TPA-based metallacycles exhibit well-defined topological structures, excellent emission characteristics, and unique functions. In this review, we systematically and comprehensively discuss the design strategies, synthetic methodologies, and practical applications for TPA-based supramolecular metallacycles, with an emphasis on five key aspects: (i) coordination-driven self-assembly, (ii) hierarchical self-assembly, (iii) supramolecular polymers, (iv) tunable fluorescence, and (v) diverse applications. Finally, future perspectives and challenges in this rapidly evolving field are presented.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
