Abstract:
A platinum complex equipped with 3-methylbenzofuryl groups was prepared and its crystal structure and emission properties were investigated. This platinum complex has two distinctly emissive polymorphs: a blue-emissive polymorph with low intensity and a brightly green-emissive polymorph. Upon mechanical stimulation, the blue-emitting phase is converted to green-emitting powder through a crystal-to-crystal phase transition. Structure analyses indicated that intramolecular interactions between ligands control the phase-transition behavior and the emission properties.

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...

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...

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.
CFT focuses on...
