What is 10,10'-Dibromo-9,9'-bianthryl (121848-75-7) used for?

10,10'-Dibromo-9,9'-bianthryl (DBrBA) exhibits modified fluorescence properties due to the internal heavy atom effect caused by bromine substitution, leading to reduced fluorescence lifetimes and quantum yields compared to its parent molecule, 9,9'-bianthryl (BA). The presence of bromine accelerates intersystem crossing from the singlet charge-transfer (1 CT) to the triplet locally excited (3 LE) state, with the spin-allowed electron transfer (3 CT → 3 LE) becoming significant in the process. Additionally, DBrBA undergoes photoreduction in the presence of aromatic donors, such as amines, forming BA, a reaction also observed electrochemically. These properties highlight its role in studying heavy atom effects and photochemical transformations.
