The supramolecular structure of perylene are attracting great interest for the preparation of organic photoconductors, organic semiconductors, solar cells semiconductor device, for technological applications. The research is based on the synthesis and study of the optical properties of perylene derivatives and their dispersion in polymeric matrix for the application in the polymeric sensors field.<br>The interaction between polymer and additive found great interesting in this work, different aggregation of the dispersed dye have been observed in dependence of the structure of polymer and perylene. Different optical properties are available by changing the conformational behaviour of the dye.<br>For this purpose three different synthetic strategies were followed:<br>· Synthesis of perylene bisimide derivatives and studied its optical properties in solution.<br>· Dispersion of the syntetised product into a polymeric matrix in order with the polarity of the dye and matrix. Studied of the optical properties of the device.<br>· The probe was tested as polymeric sensor to variation of temperature and deformation of the<br>polymer.<br>Every device (polymer-dye) show interesting optical behaviour, rendering the probe a material with possible applications in the intelligent packaging.
