摘要：
Staying in shape: The second and third generations of a new dendron system switch from left-handed to right-handed helical conformations upon a change in solvent from THF to water (picture; left). This inversion occurs in tandem with conformational shifts about the O-C-C-O bonds of a subset of terminating glycol chains, from gauche,gauche+,anti to anti,-gauche-,anti (picture; right). © 2005 Wiley-VCH Verlag GmbH & Co.
