Linear soluble sulfur atom-containing pentaphene derivatives as well as preparation method and application thereof

The invention discloses novel soluble sulfur atom-containing pentaphene derivatives as well as a preparation method and application thereof. The structural formula of the sulfur atom-containing pentaphene derivatives is shown in the formula 1-1 or 1-2. A synthetic route provided by the invention is simple and efficient; the materials are simple and easily available; a synthetic method has universality and can be popularized and applied to the synthesis of the sulfur atom-containing pentaphene derivatives containing various substituent groups. The compounds have larger pi-conjugate planes and can be used for preparing a high-mobility OFET (Organic Field Effect Transistor) apparatus by virtue of a solution method due to good solubility of the compounds. The compound has low highest occupied molecular orbital energy level (HOMO) and good stability in air, and is beneficial to obtaining the OFET apparatus which has a high mobility and a high switch ratio and is stable in air. According to the embodiment of the in
