Towards implementing hierarchical porous zeolitic imidazolate frameworks in dye-sensitized solar cells

Abstract

A one-pot method for encapsulation of dye, which can be applied for dye-sensitized solar cells (DSSCs), and synthesis of hierarchical porous zeolitic imidazolate frameworks (ZIF-8), is reported. The size of the encapsulated dye tunes the mesoporosity and surface area of ZIF-8. The mesopore size, Langmuir surface area and pore volume are 15 nm, 960–1500 m 2 · g −1 and 0.36–0.61 cm 3 · g −1 , respectively. After encapsulation into ZIF-8, the dyes show longer emission lifetimes (greater than 4–8-fold) as compared to the corresponding non-encapsulated dyes, due to suppression of aggregation, and torsional motions.

“…[ 15–17 ] However, the small pore size of ZIFs such as ZIF‐8 prevents diffusion of large molecules efficiently. Thus, several approaches were reported to increase ZIF's porosity via methods including the use of multiple linkers [ 18 ] or using a template molecule [ 8,19–23 ] or nanoparticles. [ 24 ] The synthesis of ZIF‐8 with large pore size in most cases required a template molecule as porogen additives.…”
