Abstract:
Half-lantern binuclear Pt(II) complexes bearing two heteroleptic cyclometalated 2-phenylpyridine ligands were synthesized and characterized for the first time. Heteroleptic cyclometalation is favorable for achieving an asymmetric charge distribution and for tuning optical properties. The maximum emission wavelength of the heteroleptic cyclometalated complexes is approximately half the sum of those of the corresponding homoleptic cyclometalated complexes. Moreover, their metal-induced planar chirality can be self-sorted by chiral soft-bridged thiolate ligands with a diastereoselectivity exceeding 99%.

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...

Thermal Electrocyclic Reactions: Stereochemistry
Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
