Specifications | MSDS | Literature and Reviews

1,3,6,8-tetrakis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrene is a pyrene with four boronic acid pinacolate ester side groups at 1,3,6,8-positions. Pyrene tetraboronic ester is mechanically ground fluorescence active but phosphorescence inactive. It exhibits room temperature phosphorescence in air with mechanical force due to the good communication between singlet and triplet states from the efficient intermolecular electronic coupling in the dimer formed upon scratching.

Being boron rich, 1,3,6,8-tetrakis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrene finds application in n neutron detection. By blending the fluorescent dopant in poly(vinyltoluene) matrice, it shows comparable scintillation light output and neutron capture as state-of-the art commercial scintillator.

Conjugated microporous polymer PyDF with alternating acceptor unit of fluorinated dibenzothiophene-dioxide (DBTDO) and donor units of pyrene shows excellent photocatalytic activity with an attractive photocatalytic hydrogen generation rate of 18.93 mmol h⁻¹ g⁻¹, thanks to the efficient separation of light-generated electrons and holes.
