Boronic Acid‐Functionalized Carbon Dots: From Synthesis to Multidisciplinary Applications

Abstract Boronic acid‐functionalized carbon dots (CDs) exemplify a cutting‐edge advancement in nanomaterial design, where the distinctive coordination chemistry of boron is precisely integrated with CDs synthesis to create versatile functional materials. The electron‐deficient boron modulates the core states, surface states, and electronic transition characteristics of CDs through multiple coordinated approaches, including boron doping, boronic acid groups functionalization, and B 2 O 3 matrix incorporation. These synergistic effects reveal fundamental structure‐activity relationships where boron simultaneously modulates electronic configurations, surface chemistry, and molecular recognition, providing a unified framework for designing functional carbon nanomaterials with tailored photophysical and chemical properties. These tailored modifications collectively enhance the optical characteristics, molecular recognition capabilities, and catalytic performance of CDs, enabling multidisciplinary applications across environmental monitoring, biomedical technologies, information security, and energy systems. This comprehensive review examines the fundamental boron‐carbon interactions underlying boronic acid‐functionalized CDs properties, establishes critical structure‐property relationships. By bridging molecular boron chemistry with nanoscale materials engineering, the work provides a robust framework for the rational design of next‐generation functional carbon nanomaterials through atomic‐level precision control, while advancing fundamental understanding of heteroatom doping strategies for optimized material performance.
