[0085] The present invention provides the first preparation method of the silole derivatives with the general formula (I), comprising: making the silole compound shown in the general formula (III-1) and the general formula (III-1′), ( A step in which one or more alkyne compounds shown in III-2'), (III-3'), (III-4'), (III-5') and (III-6') react,
[0086]
[0087] In the general formula (III-1), each R is independently selected from hydrogen, C 1-6 Straight chain or branched chain alkyl, each x is independently selected from integers between 0-5; each G is independently selected from hydrogen, C 1-6 Straight chain or branched chain alkyl, the group shown in formula (I-1 '), X group; Each G' is independently selected from hydrogen, C 1-6 Straight chain or branched chain alkyl, the group shown in formula (I-1 '), X group;
[0088]
[0089] In formula (I-1'), each R is independently selected from hydrogen, C 1-6 Straight-chain or branched-chain alkyl; each x is independent...
