چکیده

The dramatically different DNA-binding properties of the two isomeric forms of a photochromic spiropyran have been demonstrated, enabling photoswitched DNA binding. The closed, UV-absorbing form shows no signs of interaction with DNA. Upon UV exposure the spiropyran is isomerized to the open form that binds to DNA by intercalation. The process is fully reversible as the corresponding dissociation process is induced by visible light.

Interactions of a photochromic spiropyran with liposome model membranes.

The interactions between anionic or zwitterionic liposomes and a water-soluble, DNA-binding photochromic spiropyran are studied using UV/vis absorption and linear dichroism (LD) spectroscopy. The spectral characteristics as well as the kinetics of the thermal isomerization process in the absence and presence of the two different liposome types provide information about the environment and wheth...

Aqueous solubilization of photochromic compounds by bile salt aggregates.

Bile salts form aggregates in aqueous solutions which were shown to efficiently solubilize aqueous insoluble photochromic compounds. Photochromic switching was observed for a spiropyran and a diarylethene. In the case of the spiropyran, the incorporation into the bile salt aggregate led to improved hydrolytic stability and changes in thermal rate constants.

Functionalized polyoxometalates with intrinsic photochromic properties and their association with spiropyran cations.

The presence of alkylammonium groups covalently grafted on bisphosphonato ligands induces photochromic properties to ligand-coordinated polyoxomolybdate systems. Such intrinsically photoactive polyanions can be used for the preparation of materials combining photochromic polyoxometalates and functional countercations.

Reversible Energy-Transfer Switching on a DNA Scaffold

We show that FRET between Pacific Blue (PB) and Alexa488 (A488) covalently attached to a DNA scaffold can be reversibly controlled by photochromic switching of a spiropyran derivative. With the spiropyran in the closed spiro isomeric form, FRET occurs freely between PB and A488. UV-induced isomerization to the open merocyanine form shuts down the FRET process by efficient quenching of the PB ex...
