| 英文摘要 | Supramolecular chirality in the langmuir- schaefer (ls) films of two achiral amphiphilic schiff bases, 2-(2 '-benzimidazolyliminomethyl)-4-octadecyloxyphenoi (bsc18) and 2-(2 '-benzthiazolyliminomethyl)-4-octadecyloxyphenol (tsc18), was investigated. both of these amphiphiles could form ls films from the water surface or coordinate with ag(i) in the subphase to form ag(i)-coordinated ls films. although both of these amphiphiles were achiral, tsc18 formed a chiral ls film from the water surface, while bsc18 formed a chiral ag(l)-coordinated ls film from the aqueous agno3 subphase. the supramolecular chirality in these ls films was suggested to be due to a cooperative stereoregular pi-pi stacking of the functional groups together with the long alkyl chains in a helical sense. the relationship between the chirality of the ls films and the molecular structures of tsc18 and bsc18 as well as their h-bond or coordination behaviors was discussed. the schiff base films showed a reversible color change upon exposure to hcl and nh3 gas alternatively; however, the supramolecular chirality was irreversible during these processes. |
