Abstract Two-dimensional (2D) superlattices, formed by stacking sublattices of 2D materials, have emerged as a powerful platform for tailoring and enhancing material properties beyond their intrinsic characteristics. However, conventional synthesis methods are limited to pristine sublattices, posing significant practical challenge when it comes chemically modified sublattices. Here we report chemical method that overcomes this creating unique graphene superlattice, with monodisperse,...
