| Research Abstract |
In order to investigate the optical properties and molecular interactions in the adsorption Langmuir-Blodgett (LB) films, we have perfomed in-situ monitoring of absorption spectra during the deposition of the LB films on optical fibers. The influence of the irradiation of the laser for the molecular excitation during the deposition was investigated. Main results are summarized below.
1) The absorption spectra of merocyanine (MC) LB films show that the MC monolayr can be deposited onto the optical fibers and this measurement has high sensitivity and can evaluate thin films of less than one monolayr.
2) The malachite green (MG) adsorbed MC LB films show red-shifts due to the molecular interaction between MC and MG on the absorption spectra.
3) The absoption spectra of the adsorption LB films depsited with the 543.5nm light for MC excitation show that the irradiation of the excitation light prevents the adsorption of MG.
These results obtained here demonstrate that the in-situ optical monitoring using optical fibers is powerful method to investigate the optical properties and the molecular interactins in the adsorption LB films.
