A new asymmetric anthracene derivative with high mobility

An asymmetric anthracene derivative (4-HDPA) was designed and synthesized. With the optimization of proper scenario of fabrication process, top-contact thin film devices based on 4-HDPA exhibit mobility as high as 3.59 cm(2) V-1 s(-1), while its single-crystal devices exhibit mobility as high as 5.12 cm(2) V-1 s(-1), which is higher than the symmetrical counterpart of 4-HDPA in both single-crystal and thin film devices.
