Highly transparent metal electrodes via direct printing processes

Highlights: • Pt(NO₃)₂(ACN)₂ as a new molecular platinum complex has been introduced. • The complex shows excellent printability in nanoimprint lithography. • Pt line and grid pattern with linewidths as small as 40 nm could be printed. • The printed electrodes show resistance below 100 Ω and transmittance up to 90%. - Abstract: Transparent platinum electrodes are prepared using nanoimprint lithography of a newly developed molecular platinum complex. Thermal decomposition at moderate temperature of this complex gives rise to elemental platinum line and grid pattern with linewidths down to 40 nm. These electrodes exhibit transmittances of 90% and resistances below 100 Ω. Thus, for the first time, highly transparent electrodes are prepared by a direct soft lithographical printing process.
