promote their self-assembly with BDBA as well as the stability of the resulting assemblies in the presence of protic solvents. A model is proposed to describe how solvent choice and starting material functionality must be carefully balanced in order to shift many competing equilibria toward the formation of discrete, solublecovalentorganicpolygons. The results are expected to provide additional insight
Novel pentacenequinonederivatives 3, 7, and 10 have been synthesized via Suzuki−Miyaura coupling. Derivatives 3 and 7 having OTBS groups undergo irreversible fluoride-induced cyclization to substituted higher quinones in the presence of TBAF in dry THF using one-pot, two-step strategies in moderate yields. These functionalized higher quinone derivatives are freely soluble in THF and DMSO and can be

Terphenyl derivatives 3 and 4 having OTBS groups have been synthesized via a Suzuki-Miyura coupling reaction, These compounds undergo unprecedented irreversible cyclization to symmetrically/unsymmetrically substituted triphenylenes while carrying out the deprotection of OTBS groups using tetrabutylammonium fluoride. Terphenyl 3 also serves as a new chemodosimeter for fluoride ions.
