Molecular packing and n-channel thin film transistors of chlorinated cyclobuta[1,2-b:3,4-b′]diquinoxalines†
Abstract
Novel chlorinated cyclobuta[1,2-b:3,4-b′]diquinoxalines were synthesized and investigated in the solid state. It is found that their molecular packing can be tuned by varying the number and position of chlorine substituents, and 2,8-dichloro-cyclobuta[1,2-b:3,4-b′]diquinoxaline either in pure form or as a mixture with its regioisomer functions as n-type semiconductors in organic thin film transistors with a field effect mobility of up to 0.42 cm2 V−1 s−1 and 0.20 cm2 V−1 s−1, respectively.
