The Development of Synthetic Routes to 1,1,n,n-Tetramethyl[n](2,11)teropyrenophanes

A concise synthetic approach to 1,1,n,n-tetramethyl[n](2,11)teropyrenophanes has been developed. It involves the construction of triply-bridged pyrenophanes, during which the three bridges are installed successively using Friedel-Crafts alkylation, Wurtz coupling and McMurry reactions. At the same time, the innate regiochemical preferences of pyrene toward electrophilic aromatic substitution are relied upon to control the substitution pattern. A cyclodehydrogenation reaction is then employed to generate the teropyrene system directly in a nonplanar conformation. The crystal structure of 1,1,7,7-tetramethyl[7](2,11)teropyrenophane was determined and the teropyrene system was found to have an end-to-end bend angle of 177.9°.

Acyclic monomers which when cured are reworkable through thermal decomposition

Compounds containing unsaturated aliphatic moieties which are linked to each other by a tertiary oxycarbonyl containing acyclic moiety are basis for compositions which are cured to polymer networks which are thermally decomposable to provide residue which can be dissolved to allow repair of inoperative assemblies by replacement of inoperative components or recovery or recycling of operative elements which are affixed in assemblies by the cured compositions.
