Asymmetric induction in solid state photochemistry
… in chiral crystals was studied. Three achiral dibenzobarrelene carboxylic acid derivatives and one achiral amino dibenzobarrelene derivative were synthesized for this work. These compounds were induced to crystallize as chiral crystals by forming salts with chiral counterions. Photolysis of the …

Functional Polymer Materials: From Iptycenes to Ring-Opening Polymerizations
… In Chapter 4, we seek to synthesize a dibenzobarrelene-elaborated polyacetylene, whereby the dibenzobarrelene groups can provide stability by steric shielding, as well as a site for attaching solubilizing and functional groups. Routes based on dehydrogenation, bromination–elimination, …

Photochemistry of dibenzobarrelenes and [alpha]-adamantyl acetophenones in both the solution and crystalline state
Six di- and mono- aryl substituted dibenzobarrelene derivatives were synthesized for studies of the di-n-methane rearrangement in both solution and the solid state. The starting materials and their photoproducts were characterized by spectroscopic methods. The photoproduct ratios of these …

Synthese und Untersuchung der photochemischen und photophysikalischen Eigenschaften Donor-Akzeptor-substituierter Anthracenderivate
In der vorliegenden Arbeit wurde gezeigt, dass Donor-Akzeptor-substituierte Anthracen- und Ethenoanthracenderivate bemerkenswerte photophysikalische und photochemische Eigenschaften aufweisen. So bieten derartige Anthracenderivate eine interessante Grundlage sowohl zur Entwicklung von …
