A surface-enhanced Raman scattering study on the structure of salicylideneamine with long alkyl chains on silver colloid and silver mirror

摘要

In recent years, the study of photochromic and thermochromic materials has grown because of their possible applications in the optical processing of information in addition to the scientific interest. It is generally agreed that, in the salicylideneamine system, photoexcitation is followed by a rapid barrierless proton transfer and subsequent rearrangement to form a colored photoproduct[1]. The photochemistry of the system in fluid solution is different from that of the solid, even in fluid solution, the photo- and thermo-chromic behavior is changed with the polarity of solvent[2].
