Integrating the multiple functionalities in metalloporphyrin porous organic polymers enabling strong polysulfide anchoring and rapid electrochemical kinetics in Li–S batteries

Multifunctional POPs integrated with electrolyte accessible, Li-ion conductive, LiPS-trapping, and LiPS-catalytic functions were elaborately engineered by constructing a conformal Por(M) and imidazolium connector to form a 2D PIL framework.
