“…[3] In our case, a disubstituted triphenylamine 2 was utilized, which was then brominated by Nbromosuccinimide (NBS) to give the disubstituted triphenylamine bromide 3 (Scheme 1). The first Suzuki coupling reaction [4] was carried out with 2-thienylboronic acid and substituted triphenylamine bromide 1 under microwave irradiation.…”

Finely tuned: A stable dye-sensitized solar cell that contains a molecularly engineered organic dye has been prepared. The efficiency of the cell remains at 90% after 1000 h of light soaking at 60 degrees C. The remarkable stability of the cell is also reflected in the open-circuit voltage value (V(oc)), short-circuit photocurrent-density value (J(sc)), and the fill factor, which also show barely no decline (see picture).

“…Blue compounds 1-5 were synthesized by Horner-Wadsworth-Emmons reactions between corresponding phosphonate and carbonyl compound with moderate yields. 15 The molecular structures of the compounds were characterized by 1 H-and 13 C-NMR, FT-IR, and low-and high-resolution mass spectroscopy. High-pressure liquid chromatography (HPLC) analysis was carried out to establish purity of the blue-emitting materials (1-5) as at least above 99.0%.…”

In this paper, we reported the synthesis and electroluminescent properties of blue fluorescent styrylamine derivatives end-capped with a diphenylvinyl group. A new series of styrylamine derivatives have been synthesized via the HornerWadsworth-Emmons reaction. To explore electroluminescent properties of these molecules, multilayer organic lightemitting devices with the configuration of ITO/NPB/1-5 doped in MADN/Bphen/Liq/Al were fabricated. All devices exhibited blue emissions with good EL performances. Among those reported herein, the device using dopant 5 exhibited a maximum luminance of 24,000 cd/m 2 at 11.0 V, a luminous efficiency of 12.5 cd/A at 20 mA/cm 2 , a power efficiency of 6.50 lm/W at 20 mA/cm 2 , and CIEx,y coordinates of (x = 0.173, y = 0.306) at 8.0 V, all of which demonstrate the superiority of these materials in blue OLEDs.

“…[14] The distyrylbenzene derivative 1 displays a vibrant blue emission in toluene solution (l max = 457 nm). While limited solvatochromic shifts are observed in the absorption of 1, substantial solvent dependence is observed in emission, ranging from a structured emission of 457 nm in toluene to a broadened emission of 517 nm in a 2:1 mixture of methanol and water ( Figure 1).…”

We have investigated the UV/Vis absorption and emission of 1,4-bis(4'-dibutylaminostyryl)benzene (1) upon protonation with trifluoroacetic acid in dichloromethane and in acetonitrile. We find that 1 does not display significantly dynamic acidity in the excited state, that is, it is not a photoacid. Three protonation states of 1 were investigated, all of which, neutral, singly protonated, and bis-protonated, are fluorescent. As an isolable model for the mono-protonated species, a methylated derivative of 1 was prepared by reaction with methyl triflate. This species displays redshifted emission but similar absorption as the non-quaternized parent, 1. The strong observed emission of all three protonated states of 1 suggests that the kinetic photoacidity of 1* is low or absent. We assume that the lifetime of the excited state is too short to allow solvent reorganization and therefore we cannot make a statement on the thermodynamic photoacidity of the protonated forms of 1.
