Abstract: New indoline dye (DN319) having strong electron-withdrawing dicyanovinylidene moiety and octyl group in the terminal rhodanine ring gave higher efficiency than D205, which was known as an excellent organic dye sensitizer. This result is attributed to the bathochromic shift in the UV–vis absorption band and positive shift in the E ox level of DN319. [Copyright &y& Elsevier]

Abstract (2 R ,3a R ,8b R)- and (2 S ,3a S ,8b S)-2-Methyl indoline dye tetrabutylammonium carboxylates exhibited the highest conversion efficiency among four regio and stereo isomers. These indoline dyes also showed higher conversion efficiency than DN350. Graphical abstract 9D ‒ -Bu 4 N + exhibited the highest conversion efficiency among indoline dyes. Image 1 Highlights • Identification of indoline isomers by NMR and X-ray studies. • Solubility improvement by forming tetrabutylammonium salts. • The highest conversion efficiency of (2 R ,3a R ,8b R)- and (2 S ,3a S ,8b S)-2-methyl indoline dye tetrabutylammonium carboxylates.

An indoline dye attached with a carboxylated indan-1,3-dione moiety linked with a hexylthiophene ring exhibited the highest conversion efficiency among six analogues and D205 . This result comes from the bathochromic UV–vis absorption band, suitable energy levels, good stability for redox process, and sufficiently long excited-state lifetime. [ABSTRACT FROM AUTHOR]

The performance of a new indoline dye having a carboxylated 1,3-idandione unit linked with a hexythienyl ring showed higher conversion efficiency than the analogous dye without the hexyl group. [ABSTRACT FROM AUTHOR]

A new single rhodanine indoline dye GU112 having both cyanoacrylic and rhodanine acetic acid groups in an anchor moiety showed the best stability among GU110 , GU111 , and GU112 in zinc oxide dye-sensitized solar cell. [ABSTRACT FROM AUTHOR]

Abstract: DN350 exhibited better performance than D149 in zinc oxide dye-sensitized solar cell in the presence of cholic acid (CA). The performance of DN350 was improved in the order of cholic acids: ursodeoxycholic acid (UDCA) > chenodeoxycholic acid (CDCA) > CA. This result could come from the bathochromic shift of the UV–vis absorption band of DN350 on zinc oxide to improve short-circuit photocurrent density. [Copyright &y& Elsevier]

Abstract: A new indoline dye in which a double rhodanine acceptor is attached to the indoline moiety by a p-phenylene spacer on the indoline–nitrogen, has been examined for its performance as a sensitizer for zinc oxide dye-sensitized solar cells. In the presence of cholic acid, chenodeoxycholic acid, or lithocholic acid; the performance was greatest for lithocholic acid as this showed the greatest reduction in dye H-aggregate formation.

Abstract: The effect of N-(2-alkoxyphenyl) group in double rhodanine indoline dye on the performance of zinc oxide dye-sensitized solar cell was examined. Both J sc and V oc were improved by introducing long alkoxy group due to prevention of H-aggregates formation and inhibition of electron recombination from zinc oxide surface to electrolyte.

Abstract: The cell performance of novel benzoindoline dyes on zinc oxide prepared by template cathode electro-deposition method was compared with that of known indoline dyes. Among cyanoacrylic, single and double rhodanine acetic acid derivatives, the cyanoacrylic benzoindoline dye showed better performance than the indoline dye (D131) due to larger J sc value which comes from its positive E ox level and bathochromic UV–vis absorption band.
