dc.description.abstract |
We present a convergent synthetic route towards boron-nitrogen containing polycyclic aromatic hydrocarbons
(BN-PAHs) that allowed us to synthesize six derivatives. Starting from the conjunction of a 1,2-azaborinine nucleophile and
various aryl electrophiles, the key step was the extension of the aromatic system via an electrophilic ring closure of the
respective alkyne precursors. Our route allows to circumvent the use of substituted PAH precursors, which are often
unavailable. Instead, it builds up the BN-PAHs solely from easily accessible monocycles. All derivatives were emissive in
solution and solid state with quantum yields up to Φlum = 0.40 and small Stokes shifts. The emission wavelengths in solid
state were notably dependent on the connectivity of the rings. Due to excimer formation in one derivative, its emission was
significantly redshifted with a comparatively slow secondary photoluminescence (PL) decay. |
