Starting from the monofunctionalized
9,10-dihydro-9,10-diboraanthracene
derivatives MesB(C6H4)2BX (X = H,
Br), the bridged systems MesB(C6H4)2B–L–B(C6H4)2BMes have
been synthesized with L = −C(H)C(H)(p-C6Me4)C(H)C(H)– (5), −CC(p-C6Me4)CC– (6), and −(p-C6H4)(p-C6Me4)(p-C6H4)– (7). The compounds were characterized by NMR, IR, UV/vis, and
fluorescence spectroscopy. The vinyl- and phenylboranes 5 and 7 are pale yellow solids, whereas the alkynylborane 6 possesses a bright yellow color. The emission maxima of 5–7 in toluene are λmax(em) 477, 460, and 461 nm with quantum yields ϕf of 0.02, 0.30, and 0.04, respectively. Alkynylborane 6 was found to be the least air- and moisture-sensitive of the three
derivatives.
