Tetrapyrrolic macrocycles coordinated to redox-active main-group elements, particularly from groups 14 and 15, have emerged as efficient photocatalysts for substrate oxidation under ambient conditions. Among group 15 elements, antimony commonly adopts +III and +V oxidation states and forms stable high-valent complexes with porphyrinoid ligands such as corroles, which readily accommodate diverse axial ligands (e.g., O-, N-, and S-donors). Antimony corrole complexes exhibit considerable promise across diverse fields, including catalysis, biomedicine, and advanced dielectric and optoelectronic applications. The oxidation state of antimony plays a crucial role in modulating key reactivities such as photo- and electrochemical C-H bond activation, hydrogen evolution, and triplet-to-singlet oxygen conversion. The generation of singlet oxygen, a highly reactive species, underpins their use in catalytic oxidation and photodynamic therapy. Additionally, the tunable electronic structures of these complexes render them attractive candidates for next-generation optoelectronic and dielectric materials. This review highlights the multifunctionality of antimony corroles, encouraging further exploration of structural modifications to expand their application landscape.

When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

02:34Structural 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...

02:52Stereoisomerism
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...
