Wen-Ya Lee, Hung-Chin Wu, Chien Lu, Benjamin D. Naab, Wen-Chang Chen, Zhenan Bao*, " N-type Doped Conjugated Polymer for Non-Volatile Memory", Adv. Mater. published online. http://dx.doi.org/10.1002/adma.201605166

Development of high performance and low cost organic memory devices is crucial toward the next-generation flexible organic electronics. The organic memory techniques, however, generally require complicated multilayer fabrication processes, which increase the fabrication cost and the complexity of the devices. Herein, we used N-type doping technologies to induce non-volatile memory behavior in P-type polymer devices.

Electron. Mater. 2017, accepted.

The design of polymer semiconductors possessing high charge transport performance, coupled with good ductility, remains a challenge. We investigated the structure-property relationships (especially in both side chain and backbone engineering). The  polymer incorporated with branched side chains and an additional thiophene spacer in the backbone, exhibited improved mechanical endurance. Furthermore, this polymer exhibited a hole mobility of 0.1 cm2V-1s-1 even at 100% strain. The improved stretchability of the polymers was attributed to both the presence of soft amorphous regions and the intrinsic packing arrangement of its crystalline domains.
