On-water surface synthesis of electronically coupled 2D polyimide-MoS₂ van der Waals heterostructure.

ABSTRACT: The water surface provides a highly effective platform for the synthesis of two-dimensional polymers (2DP). In this study, we present an efficient on-water surface synthesis of crystalline monolayer 2D polyimide (2DPI) through the imidization reaction between tetra (4-aminophenyl) porphyrin (M1) and perylenetracarboxylic dianhydride (M2), resulting in excellent stability and coverage over a large area (tens of cm²). We further fabricate innovative organic-inorganic hybrid van der Waals heterostructures (vdWHs) by combining with exfoliated few-layer molybdenum sulfide (MoS₂). High-resolution transmission electron microscopy (HRTEM) reveals face-to-face stacking between MoS₂ and 2DPI within the vdWH. This stacking configuration facilitates remarkable charge t
