Abstract:Pressure-induced emission enhancement is a new and effective
way
to manipulate the color of organic materials. However, the specific
fluorescence enhancement mechanism and the causes of the color change
have not been previously well explored. Herein, two rofecoxib derivatives,
MOX2 and Y7, were synthesized with methyl sulfonyl and cyan as the
terminal groups on the para-position of the benzene
ring ② (Ph-②), and their fluorescence behavior was investigated
at 0–20 GPa. The two compounds exhibit opposite pressu… Show more
