Cyclopenta[b]thiopyran, isomeric to benzo[b]thiophene while isoelectronic to azulene, is involved as a building block to construct soluble organic semiconductors for field-effect transistors. Two series of angular-shaped heteroarenes based on cyclopenta[b]thiopyran, that is, Cn-SS (n = 4, 6, 8, 10) with different linear alkyl groups and C8-SS-Clm (m = 2, 3, 4) with chlorides substituted at different

There are provided a novel compound having a good field mobility, a method of producing of the compound, an organic semiconductor material containing the novel compound, and an organic semiconductor device. The novel compound which is represented by the following general formula (1), (2), (3) or (4) (where Z represents a sulfur atom or a selenium atom, and R represents a hydrogen atom, an alkyl group or a phenyl group in general formulae) has a structure having two benzene rings of naphthalene bonded with a thiophene ring and a selenophene ring, respectively. These compounds have a conjugate system in molecules due to an interaction between it orbitals, and show a strong molecular interaction through a sulfur atom or a selenium atom contained in a thiophene ring or a selenophene ring in each molecule, thereby having a good field mobility.
Electronic communications between S- and/or Se-heteroarenes containing cyclopenta[b]thiopyran and cyclopenta[b]selenopyran moieties have been investigated.
Three S-fused polycyclic aromatic hydrocarbons bearing cyclopenta[b]thiopyran moieties show intriguing halochromic properties in both solution and solid states. Upon alternative treatments by trifluoroacetic acid and triethylamine, the absorption and the fluorescence can be reversibly switched. It is revealed that the introduced proton is on the cyclopentadiene ring while the positive charge is localized
