Cross-Linked Polymer Based OFET Chemical Sensors for Direct Detection of Organic Solvents |
| 초록 |
Organic field-effect transistors (OFETs) chemical sensor has potential at various applications due to its advantages including easy fabrication, low cost, lightweight, processibility, and flexibility. Though organic field-effect transistors can easily fabricate by using the solution process, it can also easily be damaged by organic solvents. The poor chemical resistance of OFETs based chemical sensor limits commercialization. Herein, we study about OFET sensors which can directly detect organic solvent due to its cross-linkable azide functional group. Also, we improve the sensitivity of OFET sensors by depositing functional small molecules of calixarene derivatives. Various liquid-phase organic solvents have been detected successfully and reliable sensing responses have been obtained. Our research demonstrates a novel methodology for the fabrication of high-performance organic sensors. |
