In recent years

many researchers have an increasing interest in selenophene based polymers and oligomers in organic optoelectronic devices. So far

organic solar cells based on polyselenopheno[3

4-b]selenophene-co-benzodiselenophene(PSeB2) show higher power conversion efficiency of 6.87%

eld-effect transistors based on PSeDPP(P28)

consisting of selenophene and 3

6-dithiophen-2-yl-2

5-dialkylpyrrolo[3

4-c]

pyrrole-1

4-dione (DPP)

show higher hole mobility of 1.62cm
