Abstract Creating 3D‐engineered macroscopic architectures while inheriting the superior properties of individual building blocks remains one fundamental challenges in nanotechnology. Stable covalent interconnection between micro/nanoblocks is a desired but underexplored strategy to meet challenges, rather than current dependently‐used weak physical forces or organic cross‐linking, which disrupts continuity chemical composition and electrical properties.
