Abstract

The novel butterfly-shaped tetracarboxylic acid [9,9'-methylene- bis(9-methylfluorene-2,7-dicarboxylic acid), H4L] featuring a co- facial bifluorene core was designed and synthesised. Reactions of H4L with CdII produced the luminescent supramolecular frameworks 2 and 3, with different dimensionality and wingspan of L4–. The solid-state emission properties were rationalised based on the torsional dynamics of the facing bifluorene units by means of X- ray diffraction analysis and TD-DFT calculations.
