Abstract:
Heteroleptic PtII complexes comprising π-extended dipyrrins and 2-phenylquinoline were prepared. Single-crystal X-ray analysis disclosed the stepped conformations of two ligand moieties in these PtII complexes. The enantiomers could be separated by HPLC and their configurations were determined from CD spectroscopy results and TD-DFT calculations. Transient absorption measurements revealed excited-state dynamics characterized by fast intersystem crossing and microsecond-order triplet-state lifetimes.

π Molecular Orbitals of 1,3-Butadiene
The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the number...

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.
