In 2022,Zong, Zezhou; Zhang, Qi; Qiu, Shu-Hai; Wang, Qian; Zhao, Chengxi; Zhao, Cai-Xin; Tian, He; Qu, Da-Hui published an article in Angewandte Chemie, International Edition. The title of the article was 《Dynamic Timing Control over Multicolor Molecular Emission by Temporal Chemical Locking》.Product Details of 6149-41-3 The author mentioned the following in the article:
Dynamic control over mol. emission, especially in a time-dependent manner, holds great promise for the development of smart luminescent materials. Here we report a series of dynamic multicolor fluorescent systems based on the time-encoded locking and unlocking of individual vibrational emissive units. The intramol. cyclization reaction driven by adding chem. fuel acts as a chem. lock to decrease the conformational freedom of the emissive units, thus varying the fluorescence wavelength, while the resulting chem. locked state can be automatically unlocked by the hydrolysis reaction with water mols. The dynamic mol. system can be driven by adding chem. fuels for multiple times. The emission wavelength and lifetime of the locking states can be readily controlled by elaborating the mol. structures, indicating this strategy as a robust and versatile way to modulate multi-color mol. emission in a time-encoded manner. In the experimental materials used by the author, we found Methyl 3-hydroxypropanoate(cas: 6149-41-3Product Details of 6149-41-3)
Methyl 3-hydroxypropanoate(cas: 6149-41-3) belongs to esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
