| Abstract: | The reaction of an excess of 4, 4＇-oxydianiline (A) with alkyl halide has been foundeffective to synthesize N, N＇ -bis 2-(hydroxyethoxy)ethyl]-4, 4＇ -oxydianiline (B). It is found thattwo new pseudotaxanes (A-CPQT、B-CPQT) are formed in solution by self-assembly of electron donor4, 4 ＇ -oxydianiline (A) and (B) with electron accepter cyclobis (paraquat-phenylene) tetracationiccyclophane(CPQT), respectively, which can be reversibly switched by acid-base action. The processis monitored by 1H NMR technique. The results showed that pseudorotaxane(B-CPQT) formation isprobably encouraged by the hydrogen bonding sites.: oxygen atoms along the polyether chains fromdianiline rings form the C－H…O ] bonding with the hydrogen atoms in α position to the nitrogenatom in the bipyridinium rings on the cyclophane. |
