We report fluorescence studies of perylene in multilayers of Langmuir-Blodgett (LB) films using the time-correlated singlephoton counting technique and absorption and fluorescence spectroscopy. Evidence is presented for complex kinetics caused by the presence of isolated perylene molecules and dimer
## Abstract Langmuir and Langmuir–Blodgett (LB) films of a variety of polyoxometalates of different shapes, sizes, and charges were prepared by taking advantage of the adsorption properties of these polyanions on a positively charged monolayer of an organic surfactant spread on water. Three differe
