We demonstrate a simple method for fabricating a two-dimensional array of microdomes that consist of cyanine dye complexes. Investigation of the morphology and the fluorescence emission of microdomes was carried out before/after annealing. The principal of microdome formation is "dewetting,"

Submicrometer diameter, light emitting fibers of poly(vinyl alcohol) (PVA) doped with pseudoisocyanine (1,1'-diethyl-2,2'-cyanine bromide, PIC) dye were prepared by electrospinning. A horizontal setup was employed with a stationary collector consisting of two parallel-positioned metal strips separated by a void gap.

The trans-cis isomerization of an excited molecule converts light energy into mechanical motion, which interacts cooperatively with its surroundings. To understand such a photodynamic process in solids, we investigated the internal twisting motion of 1,1'-diethyl-2,2'-cyanine iodide (DCI) in a series
