Abstract6H-Pyrrolo[3,2-b:4,5-b']bis[1,4]benzothiazine (PBBTZ, 1) and its two 6-substituted derivatives (2 and 3) were conveniently synthesized. Their optical properties were studied by UV-vis and fluorescence spectroscopy, and electrochemical properties were investigated by cyclic voltammetry (CV). Good thermal stability was observed by thermogravimetric analysis. X-Ray analysis revealed a coplanar structure and a column stacking in the single crystal of compound 1. OFET measurements showed that 1-3 were p-type semiconductors. The performance of these devices displayed good reproducibility at ambient conditions. When devices containing 1 were fabricated on OTS-treated SiO(2)/Si substrates at 60 degrees C, the best performance was achieved with the average hole mobility as high as 0.34 cm(2) V(-1) s(-1) and the on/off ratio about 10(6)-10(7). This performance resulted from the well-ordered molecular packing as revealed by XRD and AFM analysis.
