The information in the text is summarized as follows:

This work describes (i) an eco-friendly approach for in situ immobilization of Pd nanoparticles on the surface of Fe3O4 nanoparticles, with help of green tea extract and ultrasound irradiations, without using any toxic reducing agents and (ii) development of ultrasound assisted simple protocol for synthesis of biphenyl compds RC6H5 (R = C6H5, 4-C(O)CH3C6H4, 2-thienyl, etc.). The structural, morphol. and physicochem. characteristics of the catalyst were determined by different anal. methods including inductively coupled plasma (ICP) anal., Fourier transform IR spectroscopy (FT-IR), field emission SEM (FESEM), energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM), XPS and vibrating sample magnetometry (VSM). Catalytic performance of Pd/Fe3O4 NPs as magnetic and heterogeneous catalyst was evaluated in synthesis of various biphenyl compounds throughout Suzuki coupling reactions by using the ultrasound-assisted method that was developed in this study. The Pd/Fe3O4 NPs demonstrated a noticeable catalytic activity by giving high product yields. Furthermore, the heterogeneous nanocatalyst was successfully recovered up to six times without significant activity loss. Addnl., with respect to conventional coupling reactions, the ultrasound-assisted synthesis reactions presented the advantages of green conditions, short reaction times, high yields and easier work-up. In the experiment, the researchers used many compounds, for example, 1-Iodo-4-methylbenzene(cas: 624-31-7Synthetic Route of C7H7I)

In 2022,Jia, Jingwen; Bu, Xiubin; Yang, Xiaobo published an article in Journal of Materials Chemistry A: Materials for Energy and Sustainability. The title of the article was 《A cobalt covalent organic framework: a dual-functional atomic-level catalyst for visible-light-driven C-H annulation of amides with alkynes》.Recommanded Product: 15164-44-0 The author mentioned the following in the article:

Herein, a synthesis of a dual-functional cobalt covalent organic framework (CoCOF-SYNU-1) for visible-light-driven C-H annulation of amides with alkynes was reported. An at.-level cobalt center ensures the occurrence of powerful chelation with amides and subsequent precise C-H activation, while the photoactive covalent organic framework was responsible for absorbing visible light to accelerate the catalytic cycle. In the presence of CoCOF-SYNU-1, visible-light-driven regioselective [4 + 2] C-H annulation proceeded smoothly, delivering a wide range of isoquinolin-1(2H)-one derivatives I [R1 = n-Pr, n-Bu, Ph, etc.; R2 = H, n-Pr, trimethylsilyl, etc.; R3 = H, 6-Me, 8-I, etc.; Q = 8-quinolyl] with high efficiency.

Feng, Zhao; Yu, Yue; Yang, Xiaolong; Sun, Yuanhui; Zhong, Daokun; Deng, Xuming; Zhou, Guijiang; Wu, Zhaoxin published an article in 2021. The article was titled 《Manipulating MLCT transition character with ppy-type four-coordinate organoboron skeleton for highly efficient long-wavelength Ir-based phosphors in organic light-emitting diodes》, and you may find the article in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices.Safety of 1-Bromo-3-iodobenzene The information in the text is summarized as follows:

Inspired by the intriguing optoelectronic characteristics of the 2-phenylpyridine-type (ppy-type) four-coordinate organoboron skeleton, we envisage a mol. design strategy by manipulating the MLCT transition character to develop high-performance long-wavelength Ir-based phosphors with a ppy-type four-coordinate organoboron skeleton for organic light-emitting diodes (OLEDs). Three ppy-type cyclometalated Ir(III) complexes are successfully prepared IrOBN and IrPBN exhibit the expected long-wavelength phosphorescent emission at 620 and 604 nm, resp., due to the electron-accepting ability of the pyridine coordinated with the boron atom (pyd(B)) in extending the π-conjugated length for the LUMO, thus leading to stabilization of the LUMO. Interestingly, IrMBN shows a green phosphorescence at 514 nm. The more electron-deficient pyd(B) in IrMBN leads to a reorganized and localized LUMO distribution pattern mainly on pyd(B) rather than the pyridine coordinated with the Ir atom (pyd(Ir)), shortening the π-conjugation length for the LUMO, hence resulting in an elevated LUMO. Benefiting from the high rigidity of the ppy-type four-coordinate organoboron skeleton, these three ppy-type cyclometalated Ir(III) complexes show high PLQY (ca. 0.6-1). Beneficially, we can achieve impressive electroluminescence (EL) performance based on IrPBN with the highest efficiencies of a maximum external quantum efficiency (ηext) of 26.0%, a maximum current efficiency (ηL) of 42.0 cd A-1, and a maximum power efficiency (ηP) of 38.5 lm W-1, resp. All these excellent results convincingly demonstrate the effectiveness of our mol. design strategy and the great potential of the ppy-type four-coordinate organoboron skeleton in developing high-performance Ir-based phosphors.

And the article was published in Proceedings of the National Academy of Sciences of the United States of America in 2019. Safety of 4-Iodobenzoic acid The author mentioned the following in the article:

The direction of electron flow in mol. optoelectronic devices is dictated by charge transfer between a mol. excited state and an underlying conductor or semiconductor. For those devices, controlling the direction and reversibility of electron flow is a major challenge. We describe here a single-mol. photodiode. It is based on an internally conjugated, bichromophoric dyad with chem. linked (porphyrinato)zinc(II) and bis(terpyridyl)ruthenium(II) groups. On nanocrystalline, degenerately doped indium tin oxide electrodes, the dyad exhibits distinct frequency-dependent, charge-transfer characters. Variations in the light source between red-light (∼1.9 eV) and blue-light (∼2.7 eV) excitation for the integrated photodiode result in switching of photocurrents between cathodic and anodic. The origin of the excitation frequency-dependent photocurrents lies in the electronic structure of the chromophore excited states, as shown by the results of theor. calculations, laser flash photolysis, and steady-state spectrophotometric measurements. After reading the article, we found that the author used 4-Iodobenzoic acid(cas: 619-58-9Safety of 4-Iodobenzoic acid)
