In 2022,Ling, Huan; Wu, Jianchang; Su, Fengyu; Tian, Yanqing; Yan, Jun Liu published an article in Chemical Engineering Journal (Amsterdam, Netherlands). The title of the article was 《High performance electrochromic supercapacitors powered by perovskite-solar-cell for real-time light energy flow control》.Computed Properties of C4H2Br2S The author mentioned the following in the article:
Electrochromic devices (ECDs) can alter their optical transmittances under external elec. power but are unable to spontaneously modulate the light flow in real-time along with the intensity change of surrounding light. To address this problem, a module of smart perovskite solar cell (PSC)-powered all-in-one gel ECDs was reported. The PSC-powered ECDs could modulate their transmittance swiftly in visible-IR regions, hence regulating the photo energy flow in real time according to the surrounding light intensity. The ECD based on 4, 4′-(thiophene- 2, 5-diyl)bis(1-ethylpyridin-1-ium) diiodide (TEV) showed large optical contrast (79.7% at 570 nm, 64.9% at 908 nm), excellent coloration efficiency (231.2 cm2/C), and outstanding stability (only 1.1% ΔT change after 60,000 cycles). The PSC-powered ECDs showed fast response time (≤5 s) and high stability (negligible degradation after 5000 s consecutive switching between bright and dark conditions in air). Meanwhile, the stored power accompanied with the electrochromic process could drive a red LED with high cyclic stability (95.6% of areal capacitance maintained after 10,000 charging-discharging cycles), indicating that ECDs can serve as ideal electrochromic supercapacitors (ECSs). In addition, the fabricated ECD with large area (5.0 cm x 5.4 cm) showed excellent thermal regulation (7°C of temperature difference between colored and bleached states). We expect this work would pave a new way to save energy and improve energy efficiency in modern buildings and automobiles. In the experiment, the researchers used 2,5-Dibromothiophene(cas: 3141-27-3Computed Properties of C4H2Br2S)
2,5-Dibromothiophene(cas: 3141-27-3) , is mainly used as pharmaceutical intermediate and synthesis intermediate. 2,5-Dibromothiophene may be used as starting reagent for the synthesis of α,α′-didecylquater-, -quinque- and -sexi-thiophenes.Computed Properties of C4H2Br2S
