| Outline of Final Research Achievements |
We synthesized six cellulose triacetate (CTA) derivatives having pyrene-functionalized dendrons (generations of dendrons: 1, 2, and 3; number of pyrene groups: 2, 4, and 8, respectively ) at the reducing-end: CTA-C15-N3-b-Dendron-G1Py2, CTA-N3-b-Dendron-G2Py4, CTA-C15-N3-b-Dendron-G2Py4, CTA-N3-b-Dendron-G3Py8, and CTA-C15-N3-b-Dendron-G3Py8. Those cellulose derivatives well dispersed single-walled carbon nanotubes (SWCNTs: a mixture of metallic and semiconducting SWCNTs) to afford SWCNT dispersed solutions in tetrahydrofuran (THF). Single-walled carbon nanotube field effect transistor (SWCNT-FET) was prepared with SWCNTs/CTA-C15-b-Dendron-G3Py8 complex. The field effect mobility of SWCNTs/CTA-C15-b-Dendron-G3Py8-FET was calculated to be 4.96×10-1 (cm2/V sec) as a preliminary result.
