Spiropyran-based photoswitchable dimethylaminopyridine

Embedding of DMAP in a spiropyran derivative results in a molecular switch 1, which changes the coordination capability of the DMAP moiety upon exposure to external stimuli such as light and heat. In the closed form, 1c behaves as an isolated DMAP, complexing with zinc porphyrin (ZnP) with a high binding constant (K = 1.8 × 104 M-1). However, in the open form, 1o associates with ZnP with a much weaker binding strength (K = 0.5 × 104 M-1). Switching between 1c and 1o is fast and reversible. In the photostationary state under irradiation at 330 nm, 90% of 1 is transformed from 1c to 1o.

Molecules that change conformation in response to a stimulus have numerous uses, such as artificial chemoreceptors, novel drug delivery strategies and liquid crystal technology. Here we describe the design, synthesis and conformational behaviour of an iso

experimental part, p. 3847 - 3861 (2010/05/15)
A new class of [2]catenanes containing zinc(II)-porphyrin (ZnP) and/or [60]fullerene (C60) as appended groups has been prepared. A complete description of the convergent synthetic approach based on Cu(I) template methodology and "click" 1, 3-di
