As a proof of concept for optical application of agZIF-62(Zn), we employ thermal microimprinting to generate concave and convex micro-optical components, on which the details for the shaping process are evaluated. For this purpose, we start by direct viscosity measurements beyond Tg (agZIF-62), as earlier data were available only from extrapolation using the value of Tg and the calorimetric fragility index . Using imprinting tools generated by two-photon polymerization and sintering of silica precursors (Figure ), concave and convex optical components were subsequently fabricated from agZIF-62(Zn) using these viscosity data for input (Figure ).
