Abstract: Plasmon hybridization, as a basic interaction mechanism in nanophotonics research, has gained significant attention due to its clear picture in light-matter interaction properties. This hybridization can generate modulate spectral responses, and potentially enable the design of novel photonic devices. In this study, we employ peropyrene heterodimer as a model system and apply ab initio quantum mechanical calculation to systematically investigate the regulatory effects of charge doping and static electric fields on molecular plasmon hybridization behavior. Our results reveal that charge doping significantly alters plasmon hybridization modes, transforming strong hybridization states into a single molecule dominated plasmon excitations or even inducing new hybridization effects. Moreover, electric field regulation offers more precise control, allowing fine-tuning of hybridization strength while maintaining the original framework. These findings characterize the plasmon hybridization mechanisms at the molecular scale, which may be relevant for exploring tunable nanophotonic applications based on molecular plasmons.
