Photoswitchable nonlinear optical materials about metal complexes

Abstract

Incorporating photosensitive molecules into the organic/inorganic hybrid materials may contribute to forming the photoresponsive systems. The second/third-order nonlinear optical properties can be changed via external light stimulation at an appropriate wavelength. The photochromic metal complexes seem to be the superior promising materials in the domain of photoswitchable nonlinear optics (NLO). Thus, the purpose of this review is to examine current progress of metal complexes in the field of photoswitchable NLO materials and give perspectives for the future. The overview includes the second-order and third-order NLO photoswitches NLO properties of metal complexes. Combining with the characteristics of pyrene and stilbazolium groups, we describe a kind of new photoswitchable NLO materials. The rapidly increasing investigations in this domain suggest that NLO photoswitches of metal complexes will play a critical role for inspiring applications in the future.
