Carbazole-functionalized organic photosensitizer for dye-sensitized solar cells

We designed and synthesized the photosensitive ?? -conjugated organic dyes (CB-1, CB-2 and CB-3) with the carbazole substituted triphenylamine moiety as an electron donor unit and the cyanoacetic acid moiety as an acceptor for the application as a photosensitizer of dye-sensitized solar cells. The dyes with two carbazole units connected to triphenylamine moiety (CB-2 and CB-3) showed enhanced electron donating property than the one with one carbazole moiety as an electron donor unit (CB-1), which resulted in longer absorption maximum wavelength, higher overall photon to current conversion efficiency and IPCE values. In particular, CB-3 showed an absorption maximum wavelength at 428 nm and overall solar-to-energy conversion efficiency of 7.58% at AM 1.5 illumination (100 mW.cm-2) without mask.

Hole-transporting host-Polymer series consisting of triphenylamine basic structures for phosphorescent polymer light-Emitting diodes

A series of novel styrene derived monomers with triphenylamine-based units, and their polymers have been synthesized and compared with the well-known structure of polymer of N,N′-bis(3-methylphenyl)-N,N′- diphenylbenzidine with respect to their hole-transporting behavior in phosphorescent polymer light-emitting diodes (PLEDs). A vinyltriphenylamine structure was selected as a basic unit, functionalized at the para positions with the following side groups: diphenylamine, 3-methylphenyl-aniline, 1- and 2-naphthylamine, carbazole, and phenothiazine. The polymers are used in PLEDs as host polymers for blend systems with the following device configuration: glass/indium-tin-oxide/PEDOT:PSS/polymer-blend/CsF/Ca/ Ag. In addition to the hole-transporting host polymer, the polymer blend includes a phosphorescent dopant [r(Me-ppy)3] and an electron-transporting molecule (2-(4-biphenyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole). We demonstrate that two polymers are excellent hole-transporting matrix materials for these blend systems because of their good overall electroluminescent performances and their comparatively high glass transition temperatures. For the carbazole-substituted polymer (Tg = 246 °C), a luminous efficiency of 35 cd A -1 and a brightness of 6700 cd m-2 at 10 V is accessible. The phenothiazine-functionalized polymer (Tg= 220 °C) shows nearly the same outstanding PLED behavior. Hence, both these polymers outperform the well-known polymer of N,N′-bis(3-methylphenyl)-N,N′- diphenylbenzidine, showing only a luminous efficiency of 7.9 cd A-1 and a brightness of 2500 cd m-2 (10 V).
