On November 25, 2020, Shi, Weimin; Zhang, Jingjie; Zhao, Fengqian; Wei, Wei; Liang, Fang; Zhang, Yin; Zhou, Shaolin published an article.Related Products of 321-28-8 The title of the article was Nucleophilic Aromatic Substitution of Unactivated Aryl Fluorides with Primary Aliphatic Amines by Organic Photoredox Catalysis. And the article contained the following:

A mild and transition-metal-free approach for the nucleophilic aromatic substitution (SNAr) of unactivated fluoroarenes with primary aliphatic amines to form aromatic amines was reported. This reaction is facilitated by the formation of cationic fluoroarene radical intermediates in the presence of an acridinium-based organic photocatalyst under blue-light irradiation Various electron-rich and electron-neutral fluoroarenes are competent electrophiles for this transformation. A wide range of primary aliphatic amines, including amino acid esters, dipeptides and linear and branched amines are suitable nucleophiles. The synthetic utility of this protocol is demonstrated by the late-stage functionalization of several complex drug mols. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Related Products of 321-28-8

Wang, Dinghui; Wang, Jun; Wang, Yan; Yang, Yingwei published an article in 2022, the title of the article was A Fluorescent Linear Conjugated Polymer Constructed from Pillararene and Anthracene.Reference of 1,4-Dimethoxybenzene And the article contains the following content:

Over the past few years, conjugated polymers (CPs) have aroused much attention owing to their rigid conjugated structures, which can perform well in light harvesting and energy transfer and offer great potential in materials chem. In this article, we fabricate a new luminescent linear CP p(P[5](OTf)2-co-9,10-dea) via the Sonogashira coupling of 9,10-diethynylanthracene and trifluoromethanesulfonic anhydride (OTf) modified pillar[5]arene, generating enhanced yellow-green fluorescence emission at around 552 nm. The reaction condition was screened to get a deeper understanding of this polymerization approach, resulting in an excellent yield as high as 92% ultimately. Besides the optical properties, self-assembly behaviors of the CP in low/high concentrations were studied, where interesting adjustable morphologies from tube to sheet were observed In addition, the fluorescence performance and structural architecture can be disturbed by the host-guest reorganization between the host CP and the guest adiponitrile, suggesting great potential of this CP material in the field of sensing and detection. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Reference of 1,4-Dimethoxybenzene

Elacqua, Elizabeth; Gregor, Maria published an article in 2019, the title of the article was Poly(arylenevinylene)s through Ring-Opening Metathesis Polymerization of an Unsymmetrical Donor-Acceptor Cyclophane.Recommanded Product: 146370-51-6 And the article contains the following content:

Reported are well-defined donor-acceptor alternating copolymers prepared using ring-opening metathesis polymerization (ROMP). Unsym. cyclophanedienes comprising electron-donating (4-methoxy-1-(2-ethylhexyl)oxy)benzene (MEH) and electron-accepting benzothiadiazole (BT) rings were synthesized from the corresponding [3.3]dithiaparacyclophanes. ROMP of the strained unsym. and “electronically-ambiguous” cyclophanedienes proceeded in a controlled manner in the presence of either Hoveyda-Grubbs II or Grubbs II initiator in wake of both steric and electronic encumbrance. The resulting polymers, comprising alternating BT and MEH-PPV units, are achieved in mol. weights exceeding 20k with D values ranging from 1.1-1.4. The living nature of the polymerization is verified through the formation of rod-coil and rod-rod block copolymers. Our strategy to develop previously unrealized polymers from functional building blocks featuring a locked-in D-A unit is significant in a field striving to achieve well-defined and sequence-specific materials. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Recommanded Product: 146370-51-6

On September 20, 2021, Mao, Xiaowei; Cheng, Ming; Chen, Linfeng; Cheng, Jing; Li, Haibing published an article.Electric Literature of 150-78-7 The title of the article was Host-Guest Chemistry Triggered Differential HeLa Cell Behavior Based on Pillar[5]arene-Modified Graphene Oxide Surfaces. And the article contained the following:

The regulation of surface wettability and cell adhesion behavior in a mild and unperturbed state at the interface remains a challenging task. To address this task, we adopt a strategy, based on bridging the host-guest recognition capacities of pillar[5]arene and good attachment for cell adhesion abilities of graphene oxide, to construct a smart pillar[5]arene triazole-linked naphthalene-modified graphene oxide interface. The hybrid surface exhibited a good stimuli-responsive selectivity toward arginine, as demonstrated by the wettability and cell adhesion behavior. Further studies at mol. levels indicated that the recognition mechanism of arginine was probably due to the formation of a host-guest complex driven by 蟺-蟺 stacking interactions between the cavity of pillar[5]arenes and arginine, which eventually resulted in the change in surface wettability and cellular adhesion behavior. It not only signifies a host-guest interaction strategy for the design of smart devices via the host-guest effect but also inspires the design of high-performance biointerface for affinity-adherent cells without exposing cells to harsh phys. and chem. conditions. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Electric Literature of 150-78-7
