Novel conjugated macrocycles, thiophene-substituting tetrathia[22]annulenes[2,1,2,1] (TTAs, and 5b), were synthesized through a convenient four-step procedure. They were evidenced to have high aromaticity by NMR, UV–vis absorption spectra, and calculation. Their UV–vis absorption spectra, thermal stability, electrochemical properties, thin film morphology were studied and the field-effect transistors...
A novel series of pyrene derivatives 3–6 functionalized with different aromatic substituents at 2,7-positions of the pyrene core have been readily synthesized by Suzuki coupling reactions. Single crystals suitable for X-ray crystallographic analysis of compounds 3–6 were all successfully obtained. The optical, electrochemical, and thermal properties of these newly synthesized compounds were thoroughly...
