In recent years, photochromic optical research has made ??great achievements, but you want to apply the photochromic material to optical storage, optical switches and other more in-depth application, there are many problems to be solved, such as thermal stability , fatigue resistance, non-destructive readout has been hampered photochromic material is applied to the important factor optical storage and optical switch. In order to develop and expand the application of photochromic materials, people try to connect other functional groups and photochromic functional groups together to form a multi-functional photochromic system. The graduation of small organic molecules photoluminescence background color materials, the basic principles of research progress and reviewed. On the basis of the experimental design of four functional groups containing synthesized photochromic properties with stable small molecule complexes. Complexes are four kinds of nuclear magnetic resonance spectroscopy (NMR), their chemical structure is verified. The UV - visible absor
