Moreover, the A-B-A triblock copolymer solution in a selective solvent, which is good for the block B, was explored. It was observed that the flowerlike micelles were formed, in which the central block B took on a loop conformation and the two end A blocks became a part of the micellar core. It was found that some of the soluble middle B blocks served as extended bridges between the small clusters by the poorly solvated end A blocks.
