Effect of the linkage location in double branched organic dyes on the photovoltaic performance of DSSCs

Two novel double branched D-pi-A organic dyes (DB dyes) are synthesized to investigate the influence of the linkage location in DB dyes on the performance of dye-sensitized solar cells (DSSCs), where phenothiazine is introduced as a donor, thiophene-benzotriazole unit as the pi-bridge and cyanoacrylic acid as the electron-acceptor. The photophysical, electrochemical and photovoltaic properties of the dyes are systematically investigated. The results show that the location of the linkage unit has a small effect on the physical and electrochemical properties of the dyes. However, when the dyes are applied in DSSCs, an obvious decline of short-circuit current (Jsc) and open-circuit voltage (Voc) is found by moving the linkage unit from the donor part to the pi-bridge part. The DSSC based on the dye DB-D with the linkage unit in the donor obtains an overall power conversion efficiency of 6.13%, which is about 68% higher than that (3.65%) of the DSSC based on the dye DB-B with the linkage unit in the pi-bridge. The DB-B based device exhibits a lower efficiency due to its serious aggregation and short electron lifetime. The results indicate that the linkage location of the dyes has a big effect on the performance of the DSSCs.

Bromination of 10-Phenylphenothiazine and 10-Phenylphenoxazine

The reaction of either 10-phenylphenothiazine (1) with bromine in acetic acid or the cation radical of 1 with bromide ion gives ring substitution only and in accord with customary stoichiometry for nucleophilic substitution of aromatic cation radicals.However, the reaction of 1 with pyridinium bromide perbromide (2) gives predominantly 10-phenyl ring substitution and a small amount of ring substitution products.Evidence is presented which indicates that ring substitution occurs via cation radical whereas 10-phenyl substitution proceeds via electrophilic attack on the neutral molecule 1.Substitution of 10-phenylphenoxazine (4) occurs predominantly but not exclusively on the phenoxazine ring; some bromination does occur on the 10-phenyl ring.In contrast, the reaction of 4 with bromine gives only ring mono- and disubstitution products.These results indicate that both 1 and 4 react similarly under the same conditions.

Ratiometric polymer probe for detection of peroxynitrite and the application for live-cell imaging

Peroxynitrite (ONOO?) is one of the sources of oxidation stress involved in many biological signaling pathways. The role of ONOO? being a double-edged sword in biological systems drives the development of effective detection tools. In this work, a boronate-based polymeric fluorescent probe PB-PVA was synthesized and the probe performance was evaluated. The probe exhibits ratiometric sensing of ONOO? in a range of 0?6 muM. There is good linear relationship between the probe fluorescence intensity ratio and ONOO? concentration. The probe also displays moderate selectivity towards ONOO? over other ROS. Moreover, it is water-soluble and possesses good biocompatibility which aids the imaging of ONOO? in living cells. These properties could make the probe a promising tool in in vitro study related to ONOO?

Phenothiazine-based benzoxazole derivates exhibiting mechanochromic luminescence: The effect of a bromine atom

Two phenothiazine-based benzoxazole derivates (PVB and BPVB) were designed and synthesized, and their photophysical properties were studied and compared. The results showed that both compounds emitted strong fluorescence in solution and in the solid state. Their emission wavelengths were also strongly affected by solvent polarity, indicating intramolecular charge transfer (ICT) transitions. Interestingly, the two compounds exhibited different mechanochromism. The ground film of PVB without bromine atoms can self-cure and change into the original film within 15 min at room temperature. The fluorescence of the ground film for BPVB showed no changes for at least 2 weeks. Meanwhile, a higher contrast fluorescence change was observed for the solid film of BPVB with bromine atoms under grinding, although PVB and BPVB exhibited similar spectral red shifts after grinding. Based on the spectral results and single-crystal structures, a mechanochromic mechanism is given.
