摘要：

The use of lateral substitution on the aromatic rings of the diacid component of diacid/bispyridyl AABB supramolecular LC polymers is effective at retarding crystallization presumably by introducing a 'carbuncle' along the chain which interferes with the requisite efficient close packing of molecular units. We have examined both one and two chloro groups per ring and have observed a glass transition and fiber formation in the least crystalline complex.
