摘要：
A helical mesophase with well-defined chirality of neigboring helices was stabilized in a monolayer of an ABC triblock copolymer. An almost perfect antiferromagnetic superstructure of helicity was observed. It was found that the antiferromagnetic ordering is possible in two dimensions only. The apparent coexistence between the helical morphology and core/shell cylinders in the monolayer regime indicates that the films may not have fully equilibrated.
