Naphthodithiophenediimide (NDTI): Synthesis, Structure, and Applications
摘要:
A straightforward synthesis of alpha,beta-unsubstituted and alpha-halogenated naphtho[2,3-b:6,7-b']-dithiophenediimides (NDTIs) is described. Electrochemical and optical studies of N,N-dioctyl-NDTI demonstrate that the compound has a low-lying LUMO energy level (4.0 eV below the vacuum level) and a small HOMO-LUMO gap (similar to 2.1 eV). With its interesting electronic and optical properties, in addition to its planar structure, NDTI is a promising building block for the development of novel pi-functional materials. In fact, it afforded n-channel, p-channel, and ambipolar materials, depending on the molecular modification.

amino-functionalized electron-accepting π-conjugated systems. The reaction between the ethynyl group of the electron acceptor and an amine proceeds almost quantitatively, without a catalyst, to give a Michael-addition-type product that shows remarkable changes in its optical properties, redox properties, and dipole moment. The progress of the reaction can be visually monitored in various media. On the basis
