摘要:
The co-linear or near co-linear structure of bimetallic Janus-type two-coordinated metal complexes may allow for a large transition dipole moment that can enhance the radiative lifetime. The symmetric nature of the bimetallic Janus complexes diminishes or eliminates the polar nature of the monometallic carbene-metal-amide/arene complexes.
