abstract = {Construction of π–π stacking supramolecular complexes
with more than two different components is challenging due
to the weak and directionless nature of dispersion
interactions. Here, we report ternary complexes of a ditopic
nanographene tetraimide (1), α-substituted phthalocyanine
(Pc), and polyaromatic hydrocarbons (PAHs) in solution and
the crystalline state via allosteric regulation. Binding of
one Pc gives rise to significant distortion and
conformational changes in 1 that in turn lead to the
inhibition of the second binding of Pc. The conformational
changes associated with first binding allowed an allosteric
binding of a third component (PAHs) to form ternary
complexes in solution. 1H NMR titration revealed moderately
high thermodynamic stability for the ternary complexes in
CDCl3. Competition between allosterically regulated ternary
complexes ([Pc·1·PAH]) and 1:2 stoichiometric binary
complexes of 1 with PAHs ([PAH·1·PAH]) was elucidated.
Further, the selective formation of ternary complexes in
solution led to the generation of ternary cocrystals from a
1:1:1 mixture of three components in solution. Our work
shows that large π-conjugated nanographenes designed with
allosteric recognition sites allow the construction of
multilayer ternary complexes in solution and the solid state
even with dispersive π–π interactions.},
