摘要
用红外透射、反射光谱及紫外可见吸收光谱方法研究了１－羟基－５－十二烷氧基－萘ＬＢ膜及溶液状态下的结构、分子取向。研究结果表明分子在溶液中主要是以单体形式存在；在ＬＢ膜中是以聚集体形式存在。
Ultraviolet visible(UV Vis),infrared transmission,reflection absorption(RA) and ATR spectra were used to study the mono and multi layer Langmuir Blodgett (LB) films of C 12 H 25 ONaph(1,5)OH at various temperatures to investigate dependencies of the aggregation and phase transitions on the number of monolayers.The UV vis spectra of the LB films revealed that C 12 H 25 ONaph(1,5)OH forms aggregates in the LB film.From the temperature dependence of UV vis absorption spectra,it is clear that the aggregate was gradually converted to monomer with the temperature increased.A comparison of the infrared transmission and ATR spectra reveals that the hydrocarbon chains were tilted considerably in the LB film.
