    In the present work, the energy transfer between Langmuir-Blodgett (LB) monolayers of a donor molecule (the Bisneopentyl(imido)perylene) and an acceptor molecule (the Titanylphthalocyanine) has been investigated. The Langmuir-Blodgett technique has also been used to study the distance dependence of the energy transfer, using spacer layers of arachidic acid between the donor and acceptor planes. The optical properties of the LB films have been characterized using absorption and emission spectroscopy. The energy transfer has been extracted from photoluminescence measurements and illustrated with fluorescence imaging. A discussion of the different physical models and a first estimation of the critical energy transfer distance is presented.
