| Outline of Final Research Achievements |
New concepts of organic transistor materials are developed by using metal complexes and two-component charge-transfer complexes, where a large range of redox potentials and very narrow band gaps are easily attained. By changing coordinating atoms from NO to NN and NS, p-type and ambipolar transistors are realized. Transistor characteristics are observed in many charge-transfer complexes, and it is found that orthogonality between the donor and acceptor molecular orbitals leads to n-type characteristics. Air-stable n-type transistors are realized by using birhodanine molecules with extended skeletons and fluoroalkyl groups.
