      abstract     = {A combined experimental and theoretical study of the
                      structural correlations in moderately concentrated
                      suspensions of all‐DNA dendrimers of the second generation
                      (G2) with controlled scaffold rigidity is reported here.
                      Small‐angle X‐ray scattering experiments in concentrated
                      aqueous saline solutions of stiff all‐DNA G2 dendritic
                      constructs reveal a novel anomalous liquid‐like phase
                      behavior which is reflected in the calculated structure
                      factors as a two‐step increase at low scattering wave
                      vectors. By developing a new design strategy for adjusting
                      the particle's internal flexibility based on
                      site‐selective incorporation of single‐stranded DNA
                      linkers into the dendritic scaffold, it is shown that this
                      unconventional type of self‐organization is strongly
                      contingent on the dendrimer's stiffness. A comprehensive
                      computer simulation study employing dendritic models with
                      different levels of coarse‐graining, and two theoretical
                      approaches based on effective, pair‐potential
                      interactions, remarkably confirmed the origin of this
                      unusual liquid‐like behavior. The results demonstrate that
                      the precise control of the internal structure of the
                      dendritic scaffold conferred by the DNA can be potentially
                      used to engineer a rich palette of novel ultrasoft
                      interaction potentials that could offer a route for directed
                      self‐assembly of intriguing soft matter phases and
                      experimental realizations of a host of unusual phenomena
                      theoretically predicted for ultrasoft interacting systems.},
