Used as a key building block in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to construct complex π-conjugated systems. Commonly employed in the preparation of porphyrin-based frameworks for applications in photovoltaics, sensors, and catalysis. Its boronate ester groups allow for precise assembly of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), enhancing electronic and optical properties. Also utilized in the development of organic light-emitting diodes (OLEDs) and dye-sensitized solar cells due to its tunable electronic structure and strong light absorption.
