Dithienylbenzobis(thiadiazole) based organic semiconductors with low LUMO levels and narrow energy gaps

Novel OFET materials showing high mobility (0.77 cm2 V -1 s-1) and good air-stability were developed using a benzobis(thiadiazole) (BBT) unit and the high FET performance was attributed to the low LUMO level and the film morphology.

BENZOBISTHIADIAZOLE COMPOUND, ORGANIC THIN FILM CONTAINING THE SAME, AND ORGANIC SEMICONDUCTOR ELEMENT

PROBLEM TO BE SOLVED: To provide a benzobisthiadiazole compound usable as an organic semiconductor material excellent in electron transportability and operation stability. SOLUTION: The benzobisthiadiazole compound is represented by formula (I). (X1 and X2 are each independently an alkynylene group, a thienylene group, or a thiazolylene group; Ar1 and Ar2 are each independently a pyridyl group substituted with R, an N-oxypyridyl group substituted with R, a pyrimidinyl group substituted with R, a pyrazyl group substituted with R, or a phenyl group substituted with R; R is an electron-withdrawing substituent; and when both X1 and X2 are thienylene groups, Ar1 and Ar2 are each independently a pyridyl group substituted with R, an N-oxypyridyl group substituted with R, a pyrimidinyl group substituted with R, or a pyrazyl group substituted with R).
