Abstract

A thin film semiconductor comprising a compound of formula I or II wherein: R 1 and R 2 , at each occurrence, independently are selected from a C 1-30 alkyl group, a C 2-30 alkenyl group, a C 2-30 alkynyl group and a C 1-30 haloalkyl group, R 3 , R 4 , R 5 , and R 6 independently are H or an electron-withdrawing group, wherein at least one of R 3 , R 4 , R 5 , and R 6 is an electron-withdrawing group; and a non-conductive polymer.

Claims (19)

1 . A thin film semiconductor comprising a compound of the following formula II:

wherein:

R 1 and R 2 , each independently, are selected from the group consisting of a C 1-30 alkyl group, a C 2-30 alkenyl group, a C 2-30 alkynyl group, and a C 1-30 haloalkyl group,

R 3 , R 4 , R 5 , and R 6 , each independently, are H or an electron-withdrawing group, wherein at least one of R 3 , R 4 , R 5 , and R 6 is an electron-withdrawing group; and

a non-conductive polymer.

2 . The thin film semiconductor of claim 1 , wherein R 1 and R 2 , each independently, are selected from the group consisting of a C 1-12 alkyl group and a C 1-12 haloalkyl group.

3 . The thin film semiconductor of claim 1 , wherein R 3 , R 4 , R 5 , and R 6 , each independently, are selected from the group consisting of H, F, Cl, Br, I, and —CN.

4 . The thin film semiconductor of claim 1 , wherein each of R 3 and R 4 is Br or —CN and R 5 and R 6 are H.

5 . The thin film semiconductor of claim 1 , wherein each of R 3 and R 6 is Br or —CN and R 4 and R 5 are H.

6 . The thin film semiconductor of claim 1 , wherein the compound of the formula II is

7 . The thin film semiconductor of claim 1 , wherein the non-conductive polymer is poly(methylmethacrylate).

8 . A solution comprising:

a compound of the following formula II

wherein:

R 1 and R 2 , each independently, are selected from the group consisting of a C 1-30 alkyl group, a C 2-30 alkenyl group, a C 2-30 alkynyl group, and a C 1-30 haloalkyl group,

R 3 , R 4 , R 5 , and R 6 , each independently, are H or an electron-withdrawing group, wherein at least one of R 3 , R 4 , R 5 , and R 6 is an electron-withdrawing group,

a non-conductive polymer, and

a solvent.

9 . The solution according to claim 8 , wherein the non-conductive polymer is poly(methylmethacrylate).
