In this work, we synthesize two new dyes with phenothiazine (PTZ) as π-bridge, benzothiadiazole (BTD) as acceptor moiety, and rhodanine-3-acetic acid (-RA) / cyanoacrylic acid (-CA) as anchoring group. In combination with a previously reported one with anchoring group of carboxylic acid (-CH), the effects of the three anchoring groups on material properties and the performance of dye-sensitized solar cells (DSSCs) are investigated. It is found that in terms of anchoring group for DSSC dye, the moiety features of electron-pulling ability, the spatial stretching, as well as its conjugation to the main mol. axis should be considered simultaneously. When attached over a para-Ph group to a phenothiazinyl-benzothiadiazolyl dye, among the three commonly used anchoring groups of -RA, -CA and -CH, the last one is the best, with which the CBPTZ-BTD1 based DSSC exhibits the highest power conversion efficiency of 6.69%, mainly due to the highest dye loading, open-circuit voltage, and rather high fill factor. In the experiment, the researchers used many compounds, for example, 1-Bromopyrrolidine-2,5-dione (cas: 128-08-5Name: 1-Bromopyrrolidine-2,5-dione).
1-Bromopyrrolidine-2,5-dione (cas: 128-08-5) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.Name: 1-Bromopyrrolidine-2,5-dione
