“…A polarized molecule has a asymmetric distribution of charges, a net positive charge in one place and a net negative charge in another with a suitable distance, where the dipole moment is directly related to the separated charges and their distance. In different bonds, the degree of polarity can vary greatly [39][40][41][42]. In this study, the dipole moment of the molecules in the presence of all metal atoms were computed and shown in figure 3.…”

Studing metal complexes of organic molecules has attracted great attention to explore the mechanisms of charge transfer through organometallic single molecules. In this work, we investigate the optoelectronic properties of diphenyl -bipyridine coordination chloride transition metal complex. By varying the transition metal in the group of Co, Cu, Fe, Mg, Ru and Zn atoms, we demonstrate the ability to manipulate the optical and electronic properties of the system. Density function theory (DFT) calculations with B3LYP functional are used to determine electronic properties of the metallo-molecules, including ionization potential, electronic affinity, energy gap, electronegativity, hardness, softness, and dipole moment. To understand the optical performance of the systems, we consider their absorption spectra in the ultraviolet and infrared regions, in the framework of time-dependent DFT. We argue that the six metallic atoms have the ability to tune the optoelectronic properties of the complex molecules.

The electrodynamics of active continuous media is applied to theoretically examine collective spontaneous emission regimes of dipole oscillator ensembles. Recent experiments in which the superfluorescence phenomenon has been observed are reviewed. The focus is on propagation and interaction effects experienced by the inhomogeneous waves of active center polarization and electromagnetic fields. The superradiant laser dynamics is examined and prospects for the realization of superradiant lasers using low-Q cavities are discussed.
