摘要：
We report a new synthetic method to construct supramolecular A(8)B(n) (n= 1, 2, 4) miktoarm star copolymers by host-guest complexation between a resorcinarene-based coordination capsule possessing eight polystyrene chains and 4,4-diacetoxybiphenyl guest molecules that retain one, two or four polymethyl acrylate chains. The formation of the supramolecular A8Bn (n= 1, 2, 4) miktoarm star copolymers was confirmed by dynamic light scattering (DLS), sizeexclusion chromatography (SEC), and diffusion-ordered NMR spectroscopy (DOSY). Differential scanning calorimetry (DSC) measurements revealed that the miktoarm copolymers were phase-separated in the bulk. The micro-Brownian motion of the A(8)B(4) structure was markedly enhanced in the bulk due to a weak segregation interaction between the immiscible arms.
