摘要：

A novel ionic organogel based on a polymeric charge-transfer (CT) complex was prepared. Cross-linked poly[N-[3-(dimethylamino)propyl]acrylamide] (PDMAPAA) gel was synthesized in DMF, followed by subsequent doping of 7,7,8,8-tetracyanoquinodimethane (TCNQ). The PDMAPAA gel showed extensive swelling and exhibited a green color when doped. Spectrophotometric and kinetic studies revealed that swelling and coloration are due to formation of various kinds of ionic species formed by the CT complex between the polymeric network and TCNQ, and the process of complex formation was analyzed. From Flory's theory an equation of swelling of the organogel was derived as a function of charge density of ionic species and compared with experimental results.
