Abstract
Proton transfer in organized assembly has been investigated by steady-state and picosecond time-resolved fluorescence spectroscopy. Pyranine has been incorporated into the functionalized Langmuir-Blodgett (LB) films of octadecylamine. This paper is the first example of investigating proton transfer involving pyranine in the restricted geometry of functionalized LB films. Time-resolved fluorescence spectra of pyranine in LB film matrices show that as deprotonation occurs the PyOH* band decays and the PyOâ* band builds up. It is observed that the proton transfer reactions in restricted geometry can be monitored by choosing proper parameters.
