Abstract:

For the fi rst time, thin-fi lm libraries of zinc(II) bis-2,2 ′ :6 ′ ,2 ′ ′ -terpyridine metallopolymers are prepared by inkjet printing to study structure–property relationships and their possible usage for organic photovoltaic (OPV) or polymer light-emitting diode (PLED) applications. By using a combinatorial approach, various important parameters, including solvent system, dot spacing, and substrate temperature, as well as UV-vis absorption and emission properties, are screened in a materials effi cient and reproducible manner. Homogeneous fi lms with a thickness of 150 –200 nm were obtained when printed at 40 –50 ° C and from a solvent mixture of N , N - dimethylformamide and acetophenone in a ratio of 90/10. In applications such as OPV and PLEDs the control over fi lm thickness and homogeneity are central to obtain good device properties.
