摘要：

Two is more than one: A method has been developed in which a DNA template triggers a Wittig reaction that leads to transfer of a benzylidene group from a DNA-linked phosphonium salt to a DNA-linked benzaldehyde. A synthetic receptor such as α-cyclodextrin then encapsulates the newly formed stilbene and triggers further signal increases. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
