Photo-switchable surfaces with controllable physico-chemical properties |
| abstract |
Photochromic materials, such as spiroyran dyes, are disclosed that can be used for high-density optical storage and molecular switches. According to the disclosure these compounds can be used as transducers in optical sensors. When the spiropyran dye absorbs UV light it switches to the merocyanine form, and this structure has an active binding site for cations. When cations bind to the site, the resulting colored complex has a new absorption band in the visible spectrum. By shining white or green light on the colored complex, the dye is reverted to the closed spiropyran form, and the cation is released. The disclosure optimizes the immobilization of the spiropyran dye onto a polymer substrate via long chain alkyl groups. These long chain alkyl linkers enable the dye to reversibly form the preferred merocyanine (2):(1) cation sandwich complex. |
