Project2:OxidativeDDQcyclizationinpresenceofMeSO3Hisexaminedasathree-stepapproachfromarylaceticacidsandaromaticaldehydestofunctionalizedcondensedarenes.Themethodis limitedtosystemsinwhichoneorbothofthetwoaryl moieties are more reactive than a phenyl group, such as 1-naphthyl or, especially, 3-thienyl. The extension of thisapproach to multiple cyclizations and, thus, to extended partially condensed systems with multiple alkoxycarbonylsubstituents appears promising with highly active precursors derived from 3-thienylacetic acid.

Concept

Project4:Isomericdinaphthopyrene-tetracarboxydiimideshavebeensynthesizedfollowingsimilarrouteofProject3.Theseelongated GNR fragments self assemble into columnar liquid crystals of hexagonal and rectangular symmetry, of whichrectangular mesophases have unusually elongated unit cells. The cisoid diimides show a much greater tendency to self-assembleintofluidstacksofdisksthantheircentrosymmetricisomers

Project 5: [5]helicene and [7]helicene derivatives have been synthesized by two fold Perkin condensation followed byphotocyclodehydrogenation. The helicenes combine bathochromically shifted absorption and hypsochromically shiftedfluorescencewithrespecttotheirprecursors.
