Abstract The growth and characterization of two‐dimensional (2D) crystalline boron‐carbon‐nitride (BCN) have received tremendous attention in the past decade, offering potential applications in optoelectronic and semiconductor technologies. Borazine derivatives have emerged as versatile molecular precursors for the bottom‐up synthesis of 2D BCN materials, enabling atomic‐level control over heteroatom doping and, consequently, precise tuning of the electronic band structure. This review provides a comprehensive overview of the synthetic strategies developed for organoborazines and their use as single‐source precursors for on‐surface synthesis and subsequent scanning tunneling microscopy (STM) characterization of BN‐doped carbon architectures. Particular emphasis is placed on the relationship between molecular design and resulting on‐surface supramolecular architectures. This review highlights current challenges and outlines future perspectives toward the rational design of borazine precursors for controlled BCN structures.
