Two novel donor–π–acceptor-type dithienylethene derivatives, in which the triphenylamine group acts as electron donor and the formyl group functions as electron acceptor, have been developed. Their structures were confirmed by 1H NMR, 13C NMR and HRMS (ESI). Investigation of their photochromic properties indicated that they had good photochromic behaviour and excellent fatigue resistance on irradiation with UV or visible light. DFT calculations further validated these experimental results for photochromic behaviour. Moreover, these compounds can be utilised as versatile building blocks to construct novel near-infrared photochromic materials.

Monodisperse porous polystyrene microspheres were prepared with the mixed solution of ethanol and water as dispersion medium and poly (vinylpyrrolidone) was used as dispersant. The even size of microspheres prepared at optimal process was about 1μm. Photochromic microspheres were obtained using polystyrene microspheres to absorb the photochromic materials. The effect of dispersion medium on the microspheres morphology was investigated. The adsorption parameters affecting microspheres adsorption quantity, such as the concentration of spiropyran solution and adsorption temperature, were studied in detail. Furthermore, photochromic properties of the microspheres were analyzed and PVA as coating was used to increase the fatigue resistance of photochromic microcapsules. The photochromic microspheres obtained could rapid reversibly change color under UV or sun light at room temperature and common pressure.

New photochromic 2-acylaminoderivatives of 1-p-t-butylphenoxy-9,10-anthraquinone with the various substituents in acyl groups are synthesized. The quantitative dependence of photochemical characteristics of synthesized compounds on character of substituent and nature of the solvent are established. Comparative study of their properties in solutions and polymer layers is realized. Tests show that acylaminoderivatives can be used as components of photochromic materials.

Photochromic Materials

A novel unsymmetrical diarylethene derivative containing thiophene moieties, in which a methoxy group was substituted at the para-positions of the terminal phenyl ring, was synthesized. Its photochromic properties were investigated in detail, the results indicated that the diarylethene 1o changed the color from colorless to blue, which the absorption maxima were observed at 611 and 627 nm in hexane and PMMA film when irradiation with 297 nm UV light. Additionally, the open-ring isomer of the diarylethene 1o exhibited relatively strong fluorescence at 305 nm in hexane when excited at 322 nm and the fluorescence intensity progressively decreased accompany with the photocyclization occurs. Finally, using this diarylethene as recording medium, polarization optical recording was carried out successfully.

An asymmetrical photochromic diarylethene 1-(3,5-Dimethyl-4-isoxazolyl)-2-[2-methyl-5-(p-ethoxyphenyl)-3-thienyl] perfluorocyclopentene (1o) was synthesized and its photochromic properties were investigated. Upon irradiation with 297 nm UV light, 1o exhibited photochromism in hexane solution. The kinetic experiments showed that the cyclization and cycloreversion processes were zeroth and first order reaction, respectively. Moreover, diarylethene 1o also exhibited obviously fluorescence switches along with the photochromism.
