Research Abstract

We have developed new instrument that enable us to monitor molecular behaviors at liquid/liquid interface without any perturbation. The instrument is based on Time-Resolved Quasi-Elastic Laser Scattering (QELS) method, which we have developed. In this research project, we aimed at following points, (1) To apply the QELS technique to two-dimensional imaging measurements, all necessary beams to measure QELS signal (generating scattered light and local oscillator) and QELS signals are corrected by only one lens. We can obtain two-dimensional image by scanning the lens. (2) To apply the QELS technique more widely (e.g. the samples whose one phase is turbid, liquid metal), we adopted reflective configuration. As a consequence, we succeed to develop the instrument and have applied to scientifically and industrially interesting systems as follows. (1) The dynamic molecular behavior of a phase transfer catalytic reaction at a liquid/liquid interfaces. (2) The dynamic molecular behavior of a nonlinear chemical oscillation system at water/nitrobenzene interfaces. (3) Hydrolysis reaction of phospholipid monolayer (biological membrane) by phospholipase A2 at oil/water interface. We also succeeded to improve time resolution from second to millisecond order by using new data sampling device with efficient time resolution. This improvement opens the way to monitor chemical reactions and corrective behavior of molecules at liquid/liquid interfaces which taking place in millisecond order.
