Ciou, Yan-Syun published the artcileCross-Dehydrogenative Coupling (CDC) as Key-Transformations to Various D-π-A Organic Dyes: C-H/C-H Synthetic Study Directed toward Dye-Sensitized Solar Cells Applications, Product Details of C18H12FN, the publication is Journal of Organic Chemistry (2017), 82(7), 3538-3551, database is CAplus and MEDLINE.

A variety of push-pull type organic dyes are facilely synthesized through the most atom-economical C-H/C-H dehydrogenative coupling reactions. After comprehensive synthetic optimizations, a broad substrate scope is achieved and functional groups, such as ester, ketone, nitrile, nitro, and triazene are well tolerated. The sensitive aldehyde group required for the conversion into anchoring groups for DSSCs applications is also compatible under present oxidant-containing reaction conditions. Based on this optimum C-H/C-H coupling approach, three new organic sensitizers are readily prepared and submitted to solar cell device fabrications, giving the power conversion efficiency (PCE) up to 4.85%. This work constitutes the first example that connects high atom-efficiency C-H/C-H green catalysis with dye-sensitized solar cell applications.

Wang, Lei published the artcileSite-Selective N-Arylation of Carbazoles with Halogenated Fluorobenzenes, Category: isoxazole, the publication is Synthesis (2016), 48(5), 737-750, database is CAplus.

A method for the highly site-selective C-N bond-formation reaction of halogenated fluorobenzenes with carbazoles was described. The selectivity of iodine and fluorine atoms on the aromatic ring of fluorinated iodobenzenes was initially determined with a copper-N,N-diisopropylethylamine catalytic system. By changing the position of the iodine atom on the aromatic ring from the 3- or 4-position to the 2-position, the preferred coupling site was switched from the iodine atom to the fluorine atom. Steric hindrance of the fluorinated iodobenzenes was responsible for the selectivity switch. After elucidating the reaction mechanisms of these reaction processes, a metal-free method for the highly site-selective C-N bond-formation reaction of halogenated fluorobenzenes with carbazoles was revealed through C-F bond activation. The metal-free system was able to handle a range of halogenated groups. Thus, a broad range of chlorinated, brominated, and iodinated N-arylated carbazoles were generated, which are widely useful in organic chem.

A Rh(III)-catalyzed C-H activation of boronic acid with aryl azide to obtain unsym. carbazoles, 1H-indoles, or indolines has been developed. The reaction constructs dual distinct C-N bonds via sp²/sp³ C-H activation and rhodium nitrene insertion. Synthetically, this approach represents an access to widely used carbazole derivatives The practical application to CBP and unsym. TCTA derivatives has also been performed. Mechanistic experiments and DFT calculations demonstrate that a five-membered rhodacycle species is the key intermediate.

Wu, Yehui published the artcileLow-cost and efficient hole transport materials based on 9-phenyl-9H-carbazole branch for perovskite solar cells, Name: 9-(4-Fluorophenyl)-9H-carbazole, the publication is Surfaces and Interfaces (2022), 101598, database is CAplus.

Hole transport materials (HTMs) play a pivotal role in the hole extraction and transportation processes in perovskite solar cells (PSCs). Although a great number of HTMs based on various planar conjugated cores have been explored, the development of branches is rather limited. In this work, branches of 9-phenyl-9H-carbazole derivatives have been incorporated in different N-alkylated dithieno[3,2-b:2�3�d]pyrrol (DTP) core to construct HTMs (TM-9 to TM-14). Among them, TM-13 with 9-(4-methoxyphenyl)-9H-carbazole branch exhibites excellent performance in hole extraction and transportation ability. Consequently, the PSCs based on TM-13 have achieved the power conversion efficiency (PCE) of 20.44%, which is comparable to the PCE of 20.62% with the widely used Spiro-OMeTAD HTM. More importantly, the synthetic cost of TM-13 (62 dollar/g) is much lower than that of Spiro-OMeTAD (400 dollar/g), suggesting its promising commercialization for low-cost and efficient HTMs for PSCs.

A copper nanocluster-based catalyst, [Cu₆₁(S^tBu)₂₆S₆Cl₆H₁₄] (Cu₆₁NC) that enabled C-N bond-forming reactions of aryl chlorides under visible-light irradiation at room temperature A range of N-heterocyclic nucleophiles and electronically and sterically diversed aryl/hetero chlorides react in this new Cu₆₁NC-catalyzed process to afford the C-N coupling products in good yields. Mechanistic studies indicated that a single-electron-transfer (SET) process between the photoexcited Cu₆₁NC complex and aryl halide enabled the C-N-arylation reaction.

Wu, Xiulan published the artcileFace-to-face order-packed mode promotes thermally activated delayed fluorescence to achieve stronger aggregation-induced emission, HPLC of Formula: 57103-14-7, the publication is Journal of Science: Advanced Materials and Devices (2022), 7(2), 100432, database is CAplus.

Two novel aggregation-induced delayed fluorescence materials (AIDF) FCP-BP-PXZ [9- (4-Fluorophenyl) -9H-carbazole-3-yl] [4- (10H-phenoxazine-10-yl) phenyl] methane and FCP-BP-PTZ [9- (4-Fluorophenyl) -9H-carbazole-3-yl] [4- (10H-penzothiazin-10-yl) phenyl] methane were synthesized. Experiments and mol. dynamics (MD) simulations revealed that FCP-BP-PXZ exhibits orderly face-to-face arrangement stacking mode, which inhibits non-radiation inactivation channel and reduces energy loss by restricting larger vibration and rotation of the mol. due to abundant intermol. hydrogen bonds and strong intermol. π-π interactions. FCP-BP-PTZ′s performance was hampered by erratic relaxation aggregation. The maximal external quantum efficiency (EQE_max) of non-doped and doped organic light-emitting diodes (OLEDs) constructed on FCP-BP-PXZ was 11.2% and 18.2%, resp. Furthermore, at a brightness of 1000 cd m^-2, non-doped and doped devices had a low turn-on voltage of 3.0-3.5 V, with 2.0% and 3.3% efficiency roll-off, owing to the microsecond-scale delayed lifetime. The FCP-BP-PXZ-based non-doped device, in particular, achieved a brightness of 62,390 cd m^-2, which was crucial in non-doped yellow OLEDs.

We report the synthesis and optical properties of a series of ten organic compounds with biphenyl as the backbone and asym. modified by triphenylamines, carbazoles and tetraphenylsilanes (BP 1-10). BP 1-10 were synthesized mainly by Ullmann coupling reaction and Suzuki cross-coupling reaction and characterized by EA, NMR, MS, UV-Vis, DSC, TGA, fluorescence spectra and cyclic voltammetry. They exhibit reversible electrochem. behavior with low oxidation potentials and emit intense pure-blue light with high fluorescence quantum yields (up to 80%). BP 1 was fabricated into multi-layered light-emitting diodes as blue-emitting, host and hole transport materials. Based on the performance of BP 1 and the similarity in chem. structure to those compounds reported in literature, these compounds are expected to be good and versatile hole transport, host and blue emitting materials.
