Introduction of the bulky yet strongly aggregating cholesterol units to an azobenzene dyad lead to a supramolecular polymorphism not only in its temperature-controlled but also in photo-triggered self-assembly, leading to toroids and helical fibers.
Two barbiturate dyes with regioisomeric thiophene-cored twisted π-systems show strongly enhanced emission through supramolecular polymerization. The supramolecular polymers thus formed exhibit distinct emission colors and degree of agglomeration.

Synthesis of one-dimensional nanofibers with distinct topological (higher-order structural) domains in the same main chain is one of the challenging topics in modern supramolecular polymer chemistry. Non-uniform structural transformation of supram...
