A chiral spiro compound (1a) having 1,3-dithiol units has been synthesized as a stereogenic tetrathiafulvalene analogue. Spiro 1a was resolved into two enantiomers by chiral HPLC, and they exhibited remarkable chiroptical properties featuring dehydroindene-dithiol chromophore in C2 symmetry. In addition, electrochemical properties were also investigated by using cyclic voltammetry and electronic spectra of cationic species.
The present invention is directed to novel functionalized spirocentric compounds and polymers thereof that produce hyper-rigid cross-linked membranes.

The synthesis of novel spirobisindane-based monomers for the preparation of polymers of intrinsic microporosity (PIMs) with bulky, rigid substituents is described. Polymers derived from monomers containing spiro-linked fluorene substituents display enhanced solubility and microporosity due to additional frustration of packing in the solid state.
