Molecular assembly has attracted wide attention in chemistry, condensed physics, molecular electronics, and materials sciences. However, it remains a great challenge to perform post-modulation on the assembled structures without the aid of externally applied fields. Herein, we demonstrate a combined full-weak-bonded interaction and fullerene-derivative strategy and achieve the post-modulation of layer-by-layer assembly with a precision of 5.0 Å. In the absence of external fields, the fullerene derivative exhibits a long-range interaction to boost the modulation of the assembly. Benefiting from that, a catalytic dose of fullerene derivative is able to modulate a large area of assembly, reminiscent of the catalyst in chemical reactions. This work provides an efficient and flexible approach for the catalysis and precise modulation of molecular assembly. Molecular assembly is of great importance in many fields. Here, the authors establish a strategy to post-modulate angle-mismatched layer-by-layer materials by fullerene derivatives and achieve a modulation accuracy of up to 5 Å.
