Mesostructured molecular solid material |Co(en)₃|(Zr ₂F₁₁H₂O) with enhanced photoelectronic effect

A novel molecular solid material |Co(en)₃|(Zr₂F ₁₁H₂O) containing a H-bonded assembly of [Zr ₄F₂₂O₂]^10- and [Co(en) ₃]³⁺ ions was synthesized. Moreover, we demonstrated the successful preparation of this molecular solid with a mesostructured framework using a triblock co-polymer P123 (PEO-PPO-PEO) as the structure directing agent under acidic conditions. A study on its photoelectronic property revealed that the mesostructured molecular solid material significantly enhanced the photoelectronic conversion compared to that of its bulk counterpart, which may be attributed to a remarkable increase of the density of accessible optically active sites in the mesostructured molecular solid material.
