Herein, we have designed and synthesized a series of MeO-rofecoxib based fluorophore (MORF1-6) for exploiting new promising mechanochromic luminescent (MCL) materials. Among them, MORF1 and MORF3 exhibit aggregation-induced emission (AIE) effects when the substituent is located at the ortho-position on the benzene ring of b. Meanwhile, by changing the type and position of the substituent, the corresponding compounds MORF2, MORF4, MORF5, MORF6 show aggregation caused-quenching (ACQ) behavior. These results demonstrate that the position and type of the substituent have a great effect on their fluorescent properties. Furthermore, an X-ray crystal structure anal. of MORF3 revealed that the intermol. π-π stacking was suppressed and intramol. hydrogen bonding were formed, which could effectively restrict the mol. motions, thus causing typical AIE effect and mechanochromic property. Finally, a re-writable data recording device was fabricated using MORF3 as the active material. Our mol. design strategy may provide a new avenue for achieving efficient MCL materials. In the experiment, the researchers used many compounds, for example, 4-(4-Methylpiperazin-1-yl)benzaldehyde (cas: 27913-99-1Application of 27913-99-1).
4-(4-Methylpiperazin-1-yl)benzaldehyde (cas: 27913-99-1) belongs to piperazine derivatives. Industrial applications of piperazine include the manufacture of plastics, resins, pesticides and brake fluids. Piperazines are very broad chemical group, covering a wide range of drugs from antidepressants to antihistamines. The connecting property of all these chemicals is the presence of a piperazine functional group.Application of 27913-99-1
