摘要：
Here, we synthesized the salicylidene-aniline (anil) photochromes with thiol group (thiolated Schiff base) to modify silver nanoparticles (AgNPs) surface and their photochromic properties were described. A photochromic response related to the light induced tautomerization of the anils functionality along with bathochromic shift in the absorption band is observed in AgNPs surfaces. We have also examined that enol -> keto photoisomerization rate by UV light for functionalized AgNPs are clearly faster than free anils. (C) 2016 Elsevier B.V. All rights reserved.
