摘要：

(Chemical Equation Presented) Stack 'em high: A polyimide with pyromellitic diimide units linked by hexaoxy-ethylene segments can be made to fold by cooperative two-point interactions on addition of a folding agent (see scheme). The ammonium group of the folding agent forms complexes with the oxyethylene spacer which greatly facilitates the formation of charge-transfer complexes between the aromatic units of the two components. © 2005 Wiley-VCH Verlag GmbH & Co.
