                                   Abstract

   Photochromic compounds have been applied to optical memories, optical switches, electronic paper, and other electric devices. However, in general, organic photochromic compounds have low light stability and are not suitable for long-time repetitive use or use under a harsh environment. Therefore, in this study, we tried to develop a new photochromic compound by selecting phthalocyanine, which as high light stability and thermal stability, as the skeleton of the photochromic compound and synthesizing Pc1, which was substituted for electron-withdrawing sulfonyl side chains. Synthesis of Pc1 was carried out in three stages, and the formation of Pc1 was confirmed by 1H-NMR, 13C-NMR, a UV-vis absorption spectrum, and MALDI-MS measurement.

 

Keywords: phthalocyanine, binding Sites, metal ion binding, photochromic compounds
