Usage

General Description

2,5-Dibromo-3-furancarboxylic acid, also known as CAS No. 100033-04-6, is a specialized chemical compound with the molecular formula C5H2Br2O3. It is characterized by a furan ring structure, which is a five-membered ring compound containing an oxygen atom, and has two bromine atoms and a carboxylic acid group attached to it. 2,5-Dibromo-3-furancarboxylic acid is primarily used in scientific research and is not very common in everyday applications. As with most chemicals, it should be handled with care to avoid potential risks or hazards. Its physical and chemical properties, stability and reactivity, as well as toxicological and ecological information are generally outlined in its material safety data sheet.

Simple furan-based polymers with the self-healing function enable efficient eco-friendly organic solar cells with high stability

Herein, two simple polymers PFO3 and PFO4 based on furan-3-carboxylate and 3-alkylfuran are developed. PFO3 and PFO4 feature high hole mobility, large dielectric constant and good solubility. Compared to PFO4, PFO3 with shorter oligoethylene glycol (OEG) side chains demonstrates a larger absorption coefficient and deeper electronic energy level. The air- and ethanol/water-processed OSCs based on the PFO4:fullerene derivative (PCBO-12) show a modest efficiency of 2.06%. However, PFO3:PCBO-12 OSCs yield a higher efficiency of 3.03% due to the simultaneously enhanced photovoltaic parameters. PFO3- and PFO4-based devices retain 64.5% and 51.2% of their initial efficiency after continuous illumination for 200 h in an inert atmosphere, respectively. Surprisingly, the retained efficiency ratio is increased to 81.6% and 69.1% for PFO3- and PFO4-based devices suffering from discontinuous illumination yet with the same soaking time of 200 h in an inert atmosphere. However, the above phenomenon is not observed for three other photovoltaic systems without abundant OEG groups when adopting discontinuous illumination. Infrared spectroscopy and X-ray photoelectron spectroscopy unravel that the repair efficiency of PFO3- or PFO4-based devices should have resulted from the self-healing of hydrogen bonds in the photoactive layer. Our work will provide guidance for the future design of donor polymers for eco-friendly OSCs featuring high stability.
