Block copolymer self-assembly is a widely used technique for obtaining many interesting nanostructures. Development of efficient and rapid processes for driving block copolymer selfassembly has remained a challenge. Microwave heating has attracted much attention in bioenergy production and food industry due to the advantages associated with dielectric heating effects. We report here a simple method (like microwave cooking) of microwave-heatinginduced microphase separation of a carbohydrate-based block copolymer, maltoheptaose-block
