Precious metal-free molecular machines for solar thermal energy storage.

Four benzothiazolium crown ether-containing styryl dyes were prepared through an optimized synthetic procedure. Two of the dyes ( and ) having substituents in the 5-position of the benzothiazole ring are newly synthesized compounds. They demonstrated a higher degree of photoisomerization and a longer life time of the higher energy forms in comparison with the known analogs.

Halogen-containing thiazole orange analogues - new fluorogenic DNA stains.

Novel asymmetric monomeric monomethine cyanine dyes , which are analogues of the commercial dsDNA fluorescence binder thiazole orange (), have been synthesized. The synthesis was achieved by using a simple, efficient and environmetally benign synthetic procedure to obtain these cationic dyes in good to excellent yields. Interactions of the new derivatives of with dsDNA have been investigated by absorption and fluorescence spectroscopy.
