Gas-Selective Detection using Organic Semiconducting Materials |
| 초록 |
We report on gas-selective sensing with organic field effect transistors (OFETs) based on semiconducting naphthalene diimide (NDI) derivatives with electron withdrawing groups. Organic NDI derivatives shows the formation of stable radical anions by physisorption of Lewis base gas. This is because the electron withdrawing groups enhance the π-electron deficient characteristics of the NDI core. Depending on the electron withdrawing strength of the electron withdrawing group, the stable radical anion formation behavior of NDI derivatives shows a high material dependence on the type of Lewis base; hard base, borderline base and soft base defined in hard-soft acid-base (HSAB) classification. |
