And the article was published in Organic Electronics in 2019. Formula: C14H15NO2 The author mentioned the following in the article:

Spiro-OMeTAD is the most popular hole transport material (HTM) for perovskite solar cells. The insertion of one carbonyl group into the spirobifluorene framework in spiro-OMeTAD gave a novel phenanthrenone-based hole transport material (spiro-PT-OMeTAD). It is found that the introduction of one carbonyl group into spiro-PT-OMeTAD led to a big difference in the absorption behaviors, frontier MO energy levels and hole mobilities. The steady-state photoluminescence characterization and the space-charge-limited-current measurement indicate that this phenanthrenone-based material plays an important role in hole collection and transportation in perovskite solar cells. As a result, the dopant-free perovskite solar cells based on spiro-PT-OMeTAD showed highly improved performance by exhibiting a short-circuit c.d. of 22.36 mA/cm2, an open-circuit voltage of 0.99 V, and a fill factor of 0.62% under 1 sun illumination, which gave an overall power conversion efficiency (PCE) of 13.83%, compared to 10.5% for the spiro-OMeTAD based devices. The experimental process involved the reaction of Bis(4-methoxyphenyl)amine(cas: 101-70-2Formula: C14H15NO2)

Developing hole-transporting materials (HTMs) with appropriate mol. configuration and charge mobility is important to improve perovskite solar cell (PSC) photovoltaic performance and their feasibility for commercialization. In this work, a novel pyramidal-shaped low-cost HTM coded MeOTTVT is prepared through extension of π-conjugation based on a triphenylamine core. Carbon-carbon double bonds are introduced between the core and p-methoxyl triphenylamine to improve the planarity of the HTM, favoring intermol. stacking of MeOTTVT and thus improving the hole mobility of the corresponding hole-transporting layer (HTL). The p-methoxyl triphenylamine-endowed HTM benefits from a HOMO level well-aligned with the perovskite active layer, facilitating effective hole extraction The champion PSC using an MeOTTVT-based dopant additive-free HTL yielded a power conversion efficiency (PCE) up to 21.30%, which is considered one of the best-performing PSCs employing a dopant additive-free small mol. HTM. In addition, the MeOTTVT-based dopant additive-free HTL exhibits outstanding thermal stability and high glass-transition temperature (Tg = 137.1 °C), combined with a more hydrophobic surface; PSCs based on an MeOTTVT dopant additive-free HTL exhibit outstanding stability against moisture, 1 sun illumination, and thermal stress. In the experiment, the researchers used Bis(4-methoxyphenyl)amine(cas: 101-70-2Related Products of 101-70-2)

In 2019,Synthetic Metals included an article by Berton, Nicolas; Nakar, Rana; Schmaltz, Bruno. SDS of cas: 101-70-2. The article was titled 《DMPA-containing carbazole-based hole transporting materials for perovskite solar cells: Recent advances and perspectives》. The information in the text is summarized as follows:

A review. Perovskite solar cells (PSC) based on metal-organic halide perovskites have emerged as one of the most promising photovoltaic technologies. Power conversion efficiency (PCE) has increased remarkably over the last few years from less than 10% up to certified efficiencies exceeding 23%. Selective interfacial layers play a critical role in charge extraction processes. In order to obtain high efficiencies, a hole transporting material (HTM) is required. Huge research efforts have been made to design efficient and low-cost materials. Carbazole-based HTMs are among the most promising new HTMs, in particular when they are substituted with dimethoxydiphenylamine (DMPA) units. This review gives an overview of the different classes of DMPA-containing carbazole-based HTMs and highlights the synthetic pathways, the structure-property relationship and the photovoltaic performances obtained in PSC devices. The relevance of structural variations and chem. doping processes is discussed with regard to efficiency and stability issues. In the experiment, the researchers used many compounds, for example, Bis(4-methoxyphenyl)amine(cas: 101-70-2SDS of cas: 101-70-2)

And the article was published in Chemistry of Materials in 2019. HPLC of Formula: 101-70-2 The author mentioned the following in the article:

Two asym. three-dimensional (3D) hole-transporting materials (HTMs) containing a triphenylethylene core and peripheral diphenylamine/triphenylamine moieties are first synthesized and successfully used in perovskite solar cells (PSCs). Both HTMs are obtained from facile preparation procedures and simple purification techniques. The X-ray diffraction, aggregation-induced emission properties, absorption and emission spectra, electrochem. properties, thermal stability, d. functional theory calculations, hole mobility, scanning electronic microscopy, at. force microscopy, steady-state and time-resolved photoluminescence, water contact angles, and photovoltaic parameters of the PSCs are compared. The highest power conversion efficiency increases from 12.57% (CJ-02) to 18.56% (CJ-01), rivaling that obtained from the state-of-the-art 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (spiro-OMeTAD) (18.69%). Further, the lab synthetic cost of CJ-01 is only about 15.5% of the price of com. spiro-OMeTAD, and the concentration of CJ-01 solution for device fabrication is less than half of the concentration of spiro-OMeTAD solution (30.0 vs 72.3 mg mL-1). These results demonstrate that the propeller-shaped compounds with a highly twisted conformation are readily available and promising alternative HTMs for PSCs. Moreover, an applicable strategy to design new HTMs with 3D structure for achieving highly efficient PSCs is proposed. In addition to this study using Bis(4-methoxyphenyl)amine, there are many other studies that have used Bis(4-methoxyphenyl)amine(cas: 101-70-2HPLC of Formula: 101-70-2) was used in this study.

Sun, Lihe’s team published research in Advanced Healthcare Materials in 2021 | CAS: 101-70-2

Sun, Lihe; Ouyang, Juan; Ma, Yunqing; Zeng, Zhuo; Zeng, Cheng; Zeng, Fang; Wu, Shuizhu published an article in 2021. The article was titled 《An Activatable Probe with Aggregation-Induced Emission for Detecting and Imaging Herbal Medicine Induced Liver Injury with Optoacoustic Imaging and NIR-II Fluorescence Imaging》, and you may find the article in Advanced Healthcare Materials.Application In Synthesis of Bis(4-methoxyphenyl)amine The information in the text is summarized as follows:

Whilte herbal medicines are widely used for health promotion and therapy for chronic conditions, inappropriate use of them may cause adverse effects like liver injury, and accurately evaluating their hepatotoxicity is of great significance for public health. Herein, an activatable probe QY-N for diagnosing herbal-medicine-induced liver injury by detecting hepatic NO with NIR-II fluorescence and multispectral optoacoustic tomog. (MSOT) imaging is demonstrated. The probe includes a bismethoxyphenyl-amine-containing dihydroxanthene serving as electron donor, a quinolinium as electron acceptor, and a butylamine as recognition group and fluorescence quencher. The hepatic level of NO reacts with butylamine, thereby generating the activated probe QY-NO which exhibits a red-shifted absorption band (700-850 nm) for optoacoustic imaging and generates strong emission (910-1110 nm) for NIR-II fluorescence imaging. QY-NO is aggregation-induced-emission (AIE) active, which ensures strong emission in aggregated state. QY-N is utilized in the triptolide-induced liver injury mouse model, and exptl. results demonstrate the QY-N can be activated by hepatic NO and thus be used in detecting herbal-medicine-induced liver injury. The temporal and spatial information provided by three-dimensional MSOT images well delineates the site and size of liver injury. Moreover, QY-N has also been employed to monitor rehabilitation of liver injury during treatment process.Bis(4-methoxyphenyl)amine(cas: 101-70-2Application In Synthesis of Bis(4-methoxyphenyl)amine) was used in this study.
