Highly photosensitive characteristics of organic thin film transistors (OTFTs) are reported for soluble star-shaped oligothiophenes with four π-conjugated arms. Organic phototransistors (OPTs) using 4(HPBT)-benzene exhibited high photosensitivity even at low optical powers. Using a high ratio of on-and-off current switching with low optical power, a reproducible memory operation for the OPTs is performed. The cover image shows photosensitive OTFTs using soluble star-shaped 4(HPBT)-benzene molecules, as reported on p. 2905 by Cho and co-workers.
