| 中文摘要 | uniaxially aligned triisopropylsilylethynyl pentacene (tips-pentacene) crystals over a large area were fabricated using zone-casting technique. the array of tips-pentacene displayed a high orientation degree with a dichroic ratio (dr) of 0.80. the crystals were arranged with c axis perpendicular to the substrate and the long axis of the ribbon corresponded to the a axis of tips-pentacene. the properties of the solutions and the processing parameters were shown to influence the formation of the oriented tips-pentacene crystalline array. solvent with a low boiling point (such as chloroform) favoured the orientation of the ribbon-like crystals. the concentration of the solution should be appropriate, ensuring the crystallization velocity of tips-pentacene matching with the receding of the meniscus. besides, we proved that the casting speed should be large enough to induce a sufficient concentration gradient. the orientation mechanism of tips-pentacene was attributed to a synergy of the ordered nuclei and a match between the crystallization velocity and the casting speed. field effect transistors (fets) based on the oriented tips-pentacene crystalline array showed a mobility of 0.67 cm(2) v-1 s(-1). |
