Fulgide, a kind of thermally irreversible photochromic compound, can be used for polarization holographic recording owing to its photoinduced anisotropy and photochromic property under the irradiation of linear polarization light. In this letter, a n

The isomerization kinetics of a spiropyran (1) and a spirooxazine (2) embedded in bilayer membranes of sodium 1-pentadecylhexadecyl sulfate (3) and sodium 1-undecyl dodecyl sulfate (4), respectively, were investigated. The thermal decay of 2 obeyed f

The red protonated photomerocyanine (PMCH) of spirooxazine (SPO) experiences a stepwise color modulation from red to purple and ultimately blue upon gradual addition of water. Both UV–vis absorption spectra and thermal bleaching kinetics indicate t

A series of spirooxazines containing phenanthroline were synthesized; the opened forms of such molecules have two potential metal-binding sites. By studying the photochromic and thermochromic properties of the complexes of europium ion (Eu 3+ ) with

A series of new spirooxazines (SPO) containing phenanthroline were synthesized and their photochromic properties were investigated. Photoisomerization of the spirooxazine was facilitated by electron donating groups in the indole moiety, a polar solve

The nanoparticles of a spirooxazine (SPO) and its photomerocyanine (PMC) were prepared through the reprecipitation method. Two distinct features were observed. One is that the decaying lifetime for PMC nanoparticles was 600 times of that for the disp

Often it is assumed that absorbance decays in photochromic materials with the time dependence of the photochemical kinetics, i.e. exponentially for first order kinetics. Although this may hold in the limiting case of vanishing absorbance, deviations
