Abstract

Wholly aromatic rod-rod type di-and triblock molecules, oligo (ether sulfone)-b-oligo (ether ketone) s (OES-OEK), were synthesized to study a solid-state self-assembled nanostructure. The OES and OEK segments in the block molecules form segregated crystalline domains. The energy-filtering transmission electron microscopy images revealed that the di-and triblock OES-OEK co-oligomers formed lamellar nanostructures with a periodicity of~ 9 ...
