- Abstract:
- Defined films of luminescent ruthenium(II) polypyridyl-
poly(methyl methacrylate) (PMMA) and iridium(III)
polypyridyl-polystyrene (PS) copolymers could be prepared
by ink-jet printing. The copolymers were deposited on photoresist-
patterned glass substrates. Films as thin as 120 nm
could be printed with a roughness of 1 to 2%. In addition, the
film thickness could be varied in a controlled way through the
number of droplets deposited per unit area. The topography
of the ink-jet printed films was analyzed utilizing an optical
profilometer. The absorbance and emission spectra were
measured using fast parallel UV-vis and fluorescence plate
reader.
