An orthogonal C-H borylation - cross-coupling strategy for the preparation of tetrasubstituted "A sub(2)B sub(2)"- chrysene derivatives with tuneable photophysical properties

An orthogonal C-H borylation - cross-coupling strategy for the preparation of tetrasubstituted "A sub(2)B sub(2)"- chrysene derivatives with tuneable photophysical properties

The regioselective, orthogonal functionalisation of 4,10-dichlorochrysene enables the synthesis of a variety of 2,8,4,10-"A sub(2)B sub(2) "-tetrasubstituted chrysenes. Such compounds exhibit broadened UV-vis absorption spectra, decreased band gap and higher HOMO levels compared to the par...

Zusammenfassung:The regioselective, orthogonal functionalisation of 4,10-dichlorochrysene enables the synthesis of a variety of 2,8,4,10-"A sub(2)B sub(2) "-tetrasubstituted chrysenes. Such compounds exhibit broadened UV-vis absorption spectra, decreased band gap and higher HOMO levels compared to the parent chrysene.
