Direct Synthesis of Crystalline Graphdiyne Analogue Based on Supramolecular Interactions

The
synthesis of graphdiyne with an ordered internal structure
is highly attractive for its various scientific and application investigations.
We reported herein a rational method to fabricate a graphdiyne analogue
with the help of supramolecular chemistry. The introduction of π–π/CH−π
interactions controlled the conformations of the precursors and afforded
multilayer graphdiyne analogue Ben-GDY through the wet chemical method.
The in-plane periodicity of the multilayer Ben-GDY was corroborated
by transmission electron microscopy and selected area electron diffraction,
which showed a pattern well matched with ABC-style stacking.
