Research Achievements
As described in the research proposal section, block polymers with incompatible components
naturally form periodic patterns in condensed state. These multiphase structures vary theirmorphologies depending on molecular parameters such as block chain connectivity and thedegree of molecular asymmetry. This section introduces and describes the principal
achievements brought by Matsushita’s research group. The common feature of each section fromthe viewpoint of molecules is “frustration included in the system” introduced variously bycomplex molecular design. The main text is written along with slides attached.
1.

The superlattice structures created by symmetric ABC linear terpolymers(slide #1)

The centered B block chains in ABC linear block terpolymers have to adopt bridge conformationin bulk and the B chains are forced to be suffered from weak stress, and hence they naturally givefeatured structures. A variety of compositional change is possible, but here we focus on“symmetric” molecules whose volume fractions of A and C chains are the same each other.
Polymer species adopted are I(polyisoprene), S(polystyrene) and P(poly(2-vinylpyridine), andmany ISP terpolymers were prepared based on the anionic polymerizations under vacuum. The
morphologies observed for symmetric terpolymers, whose volume fractions of I and P block arealmost the same, are shown in the slide #1. Four structures, i.e., three-phase four-layered lamellar
structure, tricontinuous gyroid structure, a cylindrical one with tetragonal symmetry andspherical structure of the CsCl type, can be seen from left to right with increasing the fraction of
the center S block. It should be noting the fact that all these have the feature of the superlattice
structures, in which I and P domains can be switched mutually.
2.

Tricontinuous double diamond structure from binary blends of linear ABC triblock

terpolymers (slide #2)
As displayed in the slide #2, two asymmetric ISP terpolymers were prepared and the structuresof their binary blends were observed, where the overall compositions were designed to keep
symmetry. Four-branched double diamond structure was stably observed by realizing weak
localization of two molecules on the phase-separated surface, in contrast to the three-brancheddouble gyroid structure for monodisperse symmetric molecules as introduced in the previous
section. This structure is conceived to be formed to earn the conformational entropy for the end
block chains by scarifying both the surface energy and junction-placement entropy. Thissymmetric but unusual morphology was created under weak stress due to the present molecular
design.
3.

Periodic and aperiodic tiling patterns from ABC star molecules(slides #3 and #4)

If each end of three different polymer chains are connected at one junction point, we can get
ABC star molecules, whose junction points have to be aligned on lines not on surfaces, andtherefore block chains are restricted to stay within the very frustrated spaces. And they naturally
form rod-based morphology. If we explore to check the order the cross-sectional view, we
naturally meet the two-dimensional space-sharing patterns, i.e., tilings. The slide #3 shows
schematic expression of the self-assembly manner of this type of molecules, and several examplesof the observed patterns are assembled on the right, which includes many periodic Archimedeantiling patterns and also an aperiodic pattern at the center. This characteristic one in a pentagon
has the feature of aperiodicity with dodecagonal symmetry as shown in the slide #4 in detail.
This non-classic ordered pattern was first discovered in metal alloy in 1982 by Prof. D. Shechtman,
who was honored as a single Nobel Prize laureate in chemistry section in 2011, whereas ourdiscovery of quasi-crystal with mesoscopic tile size in 2007 was in the memorial year of silver
jubilee of Shechtman’s first discovery in 1982.
4.

Non-classical structures in tetrablock terpolymers of the A1BA2C type(slide #5)
Tetrablock terpolymers of the A1BA2C type naturally hold frustration in molecules themselves

since A1 and A2 have to play deferent roles in self-assembly, and so forth they represent featured
morphologies. The slide #5 displays the double hexagonal and tetragonal structures from S1IS2P
terpolymers at the left-hand side, while the 3.3.4.3.4 AT structure and another quasicrystalline
tiling with dodecagonal symmetry from well-annealed binary blends of terpolymers arecompared at the right-hand side of the slide. These non-classical structures have been found to
appear covering wide composition region, indicating that these are evidently thermodynamicallystable structures. These results are owing to the frustrated molecular systems adopted in thepresent study.
