Application
4-Ethynylphenylboronic acid pinacol ester can be used:
- For the functionalization of platinum nanoparticles to leverage their photoluminescence properties.
- As an intermediate in the synthesis of covalent heterodyads of chlorophyll derivatives applicable as supramolecular light-harvesting systems.
- As an intermediate in the preparation of F-18 radiolabeled galectin-3 inhibitors, which are used as surrogate positron emission tomography (PET) tracers of TD139 and GB1107.
