abstract = {Two (BE)8-[16] annulenes were prepared and fully
characterized by experimental and quantum-chemical means
(1,E =N;2, E=O). The 1,8-naphthalenediyl-bridged
diborane(6)3 served as their common starting material, which
was treated with [Al(NH$_3$)$_6$]Cl$_3$ to form 1
(91\%yield) or with 1,8-naphthalenediboronic acid anhydride
to form 2 (93\%yield). As a result, the heteroannulenes 1
and 2 are supported by four aromatic “clamps” and may
also be viewed as NH-or O-bridged cyclic tetramers of BNB-or
BOB-doped phenalenyls. X-ray crystallography on mono-, di-,
and tetra adducts 2*thf, 2*py$_2$, and 2*py$_4$ showed that
2 is an oligotopic Lewis acid (thf/py:
tetrahydrofuran/pyridine donor). The applicability of 2 also
as a Lewis basic ligand in coordination chemistry was
demonstrated by the synthesis of the mononuclear Ag$^+$
complex [Ag(py)$_2$(2*py$_4$)]$^+$ and the dinuclear
Pb$^{2+}$ complex 6. During the assembly of 6, the
rearrangement of 2 led to the formation of two
(BO)$_9$-macrocycles linked by two BOB-phenalenyls to form a
nanom$eter-sized cage with four negatively charged,
tetracoordinated B atoms. Both 1 and 2 show several redox
waves in the cathodic regions of the cyclicvoltammograms. An
in depth assessment of the consequences of electron
injection on the aromaticity of 1 and 2was achieved by
electronic structure calculations. 1 and 2 are proposed to
exhibit aromatic switching capabilities in the [16]annulene
motif.},
