摘要：

A new twist on the block: The self-assembly of an achiral linear ABC triblock copolymer in solvents that were poor for the middle B block, good for the C block, and marginal for the A block yielded biomimetic double helices (see image), together with some triple helices. This result was reproduced in three different solvent pairs, thus suggesting that the multiple helices are thermodynamic products. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
