Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 148893-10-1, Name is O-(7-Azabenzotriazol-1-yl)-N,N,N,N-tetramethyl uronium hexafluorophosphate, molecular formula is , belongs to benzoxazole compound. In a document, author is Chernyshev, Anatoly V., Name: O-(7-Azabenzotriazol-1-yl)-N,N,N,N-tetramethyl uronium hexafluorophosphate.
The obtained spiroindolinebenzopyrans bearing benzoxazole fragment in the position 8 of the benzopyran part appear as polychromogenic molecular systems exhibiting not only photochromic but also ionochromic properties. Photochromic properties demonstrate variability of spectral kinetic characteristics in the wide range depending on structural features and a solvent nature. Efficiency of photocoloration process is more than one order of magnitude higher than the photobleaching quantum yield. Owing to the presence of a benzoxazole fragment ionochromic properties allow detecting presence of such metal cations as Co2+, Ni2+, Zn2+,Cu2+, Cd2+. Exemplified by Ni2+, Zn2+ ionochromic effect has been quantitatively described. Combination of photochromism and ionochromism in the obtained spiropyrans afford an opportunity to create metal ion chemosensor with photodriven recognition function.
