Abstract: vectored non-covalent interactions—mainly hydrogen bonding and aromatic interactions—extensively contribute to (bio)-
organic self-assembling processes and significantly impact the physicochemical properties of the associated superstructures.
However, vectored non-covalent interaction-driven assembly occurs mainly along one-dimensional (1D) or three-dimensional
(3D) directions, and a two-dimensional (2D) orientation, especially that of multilayered, graphene-like assembly, has been
reported less. In this present research, by introducing amino, hydroxyl, and phenyl moieties to the triazine skeleton, supramolecular layered assembly is achieved by vectored non-covalent interactions. The planar hydrogen bonding network results in
high stability, with a thermal sustainability of up to about 330 °C and a Young’s modulus of up to about 40 GPa. Upon
introducing wrinkles by biased hydrogen bonding or aromatic interactions to disturb the planar organization, the stability
attenuates. However, the intertwined aromatic interactions prompt a red edge excitation shift effect inside the assemblies,
inducing broad-spectrum fluorescence covering nearly the entire visible light region (400–650 nm). We show that bionic,
superhydrophobic, pillar-like arrays with contact angles of up to about 170° can be engineered by aromatic interactions using
a physical vapor deposition approach, which cannot be realized through hydrogen bonding. Our findings show the feasibility
of 2D assembly with engineerable properties by modulating vectored non-covalent interactions.
