<P>Summary: A simple method to prepare surfactant-free and solvent-free semiconducting polymer particles by using an environmentally benign supercritical carbon dioxide (scCO<SUB>2</SUB>) process is reported. The process of the rapid expansion of supercritical solutions (RESS) is used to produce spherical particles of poly[2-(3-thienyl)acetyl 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctanoate] (PSFTE), 50–500 nm in size, from 0.1–0.5 wt.-% PSFTE solutions in CO<SUB>2</SUB> at pre-expansion temperatures of 40 °C and pre-expansion pressures of 276 bar.</P><P>
