      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.},
