| 英文摘要 | a strong and broad hydrogen bonded o-h band around 3520 cm(-1) is observed in the insoluble monolayer of the neutral liquid crystal molecules of 4 ''-n-pentyl-4-p-cyanobiphenyl (5cb) and 4 ''-n-octyl-4-p-cyanobiphenyl (8cb) throughout the whole surface density range, but not in the 4-pentyl-4'-cyanoterphenyl (5ct) monolayer, at the air/water interface. this novel spectral feature suggests the existence of an oriented water cluster species which has penetrated or accommodated into the langmuir monolayer of the 8cb and 5cb molecules. this finding provided a molecular level mechanism for the stark difference in the phase behaviour between the cb and ct insoluble langmuir monolayers at the air/water interface. it also calls for attention to the details of the specific water-surface interaction in mediating the structure and the phase behaviour of the molecular assemblies at the heterogeneous aqueous interfaces. |
