The present invention relates to a benzodithiophene based copolymer containing thieno[3,4-b]thiophene units and a preparing method and applications thereof. The polymer has a structural formula (I), wherein R
1
and R
2
are respectively selected from H, and alkyl groups of C
1
to C
16
; R
3
and R
4
are respectively selected from H, alkyl groups of C
1
to C
16
, alkoxy groups of C
1
to C
16
, or thiophene groups substituted by alkyl groups of C
1
to C
16
; R
5
is selected from alkyl groups of C
1
to C
16
; n is a natural number from 7 to 80. Applications of the benzodithiophene based copolymer containing thieno[3,4-b]thiophene units in polymer solar cells, polymer organic light-emission, polymer organic field effect transistors, polymer organic optical storage, polymer organic nonlinear materials or polymer organic laser are also provided.
