title: 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 cm(2) V(-1) s(-1) and 0.20 cm(2) V(-1) s(-1), respectively.
