Abstract
AbstractVapor deposition method was used to obtain nanocrystals of N‐(3,5‐di‐tert‐butylsalicylidene)‐4‐ aminopyridine (1) and N‐(3,5‐di‐tert‐butylsalicylidene)‐4‐iodoaniline (2), and nanoscale thin layers (65 nm thick) of cis‐1,2‐dicyano‐1,2‐bis(2,4,5‐trimethyl‐3‐thienyl)ethene (3). Compound 3 was also deposited on a substrate previously covered by gold nanoparticles (Ø = 100 nm). Nanoscale crystals of 1 and 2 showed similarities with bulk crystals: they exhibit photochromic properties and they have similar shapes according to Atomic force microscopy (AFM) investigations. The thin layers of 3, with and without gold nanoparticles, showed light‐induced absorption change in the visible. Copyright © 2007 John Wiley & Sons, Ltd.
