| dc.description.abstract | In recent years, with global environmental changes and increasing energy demands, green energy research has gained significant attention. Perovskite solar cells, as one of the directions of green energy research, have garnered attention mainly due to their simple production process, long lifespan, scalability, and high conversion efficiency. Perovskite solar cells have been a focal point for many research teams.
Acenes exhibit excellent potential in the optoelectronic field due to their good optoelectronic properties, performing well in many optoelectronic materials. However, acenes suffer from poor stability and complex synthesis methods, making them difficult to synthesize. Consequently, converting acenes into heteroacenes has become the goal of many research teams. Compared to acenes, heteroacenes improve on the drawbacks of acenes by being more stable and easier to synthesize. Many teams are now applying heteroacenes in optoelectronic materials, yielding excellent results.
Pyrroloindacenodithiophene (NIDT or PIDT) is a type of heteroacene compound that is easy to synthesize, cost-effective, and exhibits high planarity. Previous research teams have used pyrroloindacenodithiophene as a substrate in optoelectronic device materials such as organic light-emitting diodes (OLEDs), organic field-effect transistors (OFETs), and other optoelectronic devices. Our team focuses on perovskite solar cells, using pyrroloindacenodithiophene as the core molecule, and incorporating π-bridges between the end groups and the core molecule to increase the π-conjugation length of pyrroloindacenodithiophene. The π-bridges used are thiophene and 3,4-ethylenedioxythiophene (EDOT).
Most research teams employ cross-coupling reactions between the core molecule and the end groups using named reactions, which are complex and involve environmentally harmful reagents. Our team has adopted a step-economical synthesis method to replace traditional named reactions, aiming to reduce synthesis costs and avoid the use of environmentally harmful reagents while achieving good yields and efficient optoelectronic conversion. | en_US |
