Soluble Twisted Diarenoperylenes: Synthesis, Characterization, and Device Performance.

Two stable TIPS-ethynyl functionalized polycyclic aromatic hydrocarbons (PAHs), dibenzo[ a, j]perylene (TIPS-DBP), and dinaphtho[ a, j]perylene (TIPS-DNP), which contain two rows of linear acenes joined by benzene rings, have been synthesized and characterized. It is found that the two twisted PAHs easily form one-dimensional charge-transport systems with short C-C contacts. The crystal of TIPS-DBP shows a hole mobility up to 0.17 cm2 V-1s-1, while the crystal of TIPS-DNP shows a hole mobility up to 0.74 cm2 V-1 s-1.
