New Advances in Chemical Research, April 2021.The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 2835-95-2, Name is 5-Amino-2-methylphenol, SMILES is C1=C(N)C=CC(=C1O)C, belongs to naphthyridine compound. In a document, author is Xiao, Fuming, introduce the new discover, Computed Properties of https://www.ambeed.com/products/2835-95-2.html.
For a specific fluorescent molecule, the increase of molecular conformation distortion is beneficial to endow it with aggregation-induced emission (AIE) and mechanofluorochromic (MFC) properties. Herein, 3,5-diphenyl-4H-pyran derivative5and 4,5-diphenyl-2,7-naphthidine derivative7with highly twisted conformations were synthesized. For compound5, although the introduction of phenyl rings with large steric hindrance at 3 and 5 positions of the 4H-pyran skeleton realized the transformation from aggregation-induced quenching (ACQ)-active molecule to AIE-active molecule, it only showed a low-contrast MFC activity. Compound7was accidentally obtained from compound5andn-butylamineviaa ring-opening and subsequent intramolecular ring-closing mechanism. Compound7was confirmed to have a highly twisted molecular conformation by the crystal structural analysis and exhibited AIE activity originated from the restriction of intramolecular rotation. Furthermore, compound7exhibited reversible high-contrast MFC activity. Upon grinding, the change of solid-state fluorescence color from orange to yellow was confirmed to be due to the partial destruction of crystal structure. This work provides new ideas for the design and synthesis of novel AIE-active and MFC-active fluorescent molecules based on ACQ-active parent molecules.
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. If you like, you can also browse other articles about this kind.
