Abstract：Since SF6 is the most potent greenhouse gas with the highest global warming potential, the search for a viable alternative is a world-widely hot topic with considerable challenges. Developments of structure-activity relationship and molecular design on the replacement dielectric gases for SF6 were reviewed to breakthrough the bottleneck of both experimental and theoretical studies. Various models to predict the dielectric strengths of arbitrary insulation gases were detailed in terms of idea, methodology, and limitations. New protocols for the molecular design of the novel alternative gases were presented on the basis of the a priori theoretical models and quantum chemical calculations. The present review sheds new lights on the rational molecular design of new chemistries and will inspire experimental synthesis and field tests on the environmentally sustainable dielectric gases.
