Stereoisomerism

Stereoisomerism

Isomerism in Complexes
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...

Colors and Magnetism

Colors and Magnetism

Color in Coordination Complexes
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...

Metal-Ligand Bonds

Metal-Ligand Bonds

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
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...

Background:

Luminescent supramolecular coordination complexes (SCCs), including 2D-metallacycles and 3D-metallacages, are increasingly used for biomolecular analysis.
Unlike small-molecule probes, SCCs offer tunable dimensions, size, shape, and flexibility through ligand and metal ion selection.
Their well-defined cavities and programmable non-covalent interactions enable highly selective guest binding.

Purpose of the Study:

To review the applications of luminescent metallacycles and cages in binding and detecting diverse biomolecules.
To explore how the structural diversity of SCCs impacts biomolecular sensing capabilities.
To analyze the sensitivity, selectivity, and detection range of SCC-based biosensors.

Main Methods:

Review of literature on luminescent supramolecular coordination complexes (SCCs) for biomolecular sensing.
Analysis of structural features of 2D-metallacycles and 3D-metallacages.
Evaluation of sensing performance metrics: sensitivity, selectivity, and detection range.

Main Results:

Luminescent SCCs exhibit significant potential for detecting a wide array of biomolecules, including carbohydrates, proteins, amino acids, and biogenic amines.
Structural tunability of SCCs directly influences their binding affinity and detection capabilities.
The design of ligands and metal ions allows for precise control over cavity size, shape, and guest recognition.

Conclusions:

Luminescent SCCs are versatile platforms for advanced biomolecular detection.
Structural engineering of SCCs is key to enhancing sensitivity and selectivity in biosensing.
Further research into SCCs promises improved analytical tools for complex biological samples.
