摘要:Disclosed are a 2,8-disubstituted tetracene derivative represented by formula (I), a preparation method therefor, and the use thereof. The compound can be used for preparing an organic semiconductor device, particularly an organic field-effect transistor (OFET). A single crystal and a thin-film device, as prepared from the above-mentioned tetracene derivative, have a higher mobility, threshold voltage and switch ratio. The preparation method is simple, can greatly increase the yield of 2,8-dibromotetracene, reduces the number of post-treatment steps of intermediates, increases the synthetic efficiency, reduces the preparation time, and has a relatively low cost. The total yield of the synthesis route reaches approximately 50%. The present invention is very suitable for scaled-up preparation in a laboratory, and can provide sufficient raw materials for the preparation of a photoelectronic device containing the tetracene derivative.
