Abstract:
In this work, a systematic exploration was conducted on the solution-state photophysical and optical properties of a series of enantiomeric clusters. The enantiomeric clusters exhibit aggregation-induced emission characteristics and yield circular dichroism signals with distinct Cotton effects that display perfect mirror-image relationships. Furthermore, we observed the phenomenon where aggregation significantly attenuates their circular dichroism signals. Cytotoxicity assays confirm the good biocompatibility of the clusters, demonstrating their potential for cell imaging applications.

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

Colors and Magnetism
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 eye.
