Organic light-emitting diodes (OLEDs) have great potential applications in display and solid-state lighting. Stability, cost, and blue emission are key issues governing the future of OLEDs. The synthesis and photoelectronics of 3 kinds of binaphthyl (BN) derivatives are reported. BN_1-3 are melting-point-less and highly stable materials, forming very good, amorphous, glass-like films. They decompose at temperatures ≤485-545°. At a constant c.d. of 25 mA cm^-2, an ITO/BN₃/Al single-layer device has a much-longer lifetime (>80 h) than that of an ITO/NPB/Al single-layer device (8 h). Also, the lifetime of a multilayer device based on BN₁ is longer than a similar device based on NPB. BNs are efficient and versatile OLED materials: they can be used as a hole-transport layer (HTL), a host, and a deep-blue-light-emitting material. This versatility may cut the cost of large-scale material manufacture More importantly, the deep-blue electroluminescence (emission peak at 444 nm with CIE coordinates (0.16, 0.11), 3.23 cd A^-1 at 0.21 mA cm^-2, and 25200 cd m^-2 at 9 V) remains very stable at very high current densities up to 1000 mA cm^-2. This study involved multiple reactions and reactants, such as 3-Bromo-9-(4-fluorophenyl)-9H-carbazole (cas: 922721-30-0Formula: C18H11BrFN).

3-Bromo-9-(4-fluorophenyl)-9H-carbazole (cas: 922721-30-0) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Formula: C18H11BrFN

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.

Low-cost and efficient hole transport materials based on 9-phenyl-9H-carbazole branch for perovskite solar cells was written by Wu, Yehui;Gong, Zhiming;Jiang, Yue;Wang, Ru;Xu, Dongdong;Xu, Zhengjie;Zhou, Guofu;Liu, Jun-Ming;Gao, Jinwei. And the article was included in Surfaces and Interfaces in 2022.Quality Control of 3-Bromo-9-(4-fluorophenyl)-9H-carbazole The following contents are mentioned in the article:

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.

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.

Site-Selective N-Arylation of Carbazoles with Halogenated Fluorobenzenes was written by Wang, Lei;Ji, Enhui;Liu, Ning;Dai, Bin. And the article was included in Synthesis in 2016.Synthetic Route of C18H11BrFN The following contents are mentioned in the article:

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.
