During the last two decades, different kinds of organic p-conjugates materials have been synthesized and characterized as semiconductors used in field effect transistors (OFETs), organic light emitting devices (OLEDs), photovoltaic cells or fuel cells, due to optical and semiconductor properties, combined with their excellent thermal stabilities. The films obtained from polyfluorene compounds are most used in these optoelectronic applications, which allow the charge transfer been part of these devices. The synthesis sand rational characterization of fluorene derivatives improve the characteristics mentioned by different techniques: Calorimetry, X-ray Diffraction, UV-Visible and Fluorescence Spectroscopies. Due to the technological applications mentioned before, this work describes the characterization of their respective properties, establishing a relationship between molecular packing and emission bands as a possible technological control parameter.
