Effects of Blending and Chirality on Core-Cyanated Chiral Perylene Diimides and Biopolymer Based Phototransistors |
| 초록 |
Charge trapping effect, which reduces the charge carrier mobility, has been generally considered as a pitfall for organic semiconductors. However, introducing the charge trapping effect between the organic semiconductor layer and polar polymer dielectric layer becomes an alternative method to enhance the optical performance of organic phototransistors. Herein, organic phototransistors using enantiomeric or racemic air-stable n-type organic semiconductor PDI-derivative PDI-2CN-C6 with insulating biopolymer polylactic acid were fabricated and investigated. In comparison with pure PDI-2CN-C6 based phototransistors, the blending system greatly enhanced figure of merits of the devices. In addition, significant effects of chirality on the optoelectronic performance of the devices were observed. Our systematic study provides a feasible and effective method for high-performance n-type organic phototransistors. |
