The two linear poly(phenyleneethynylene) structures 88 and 89 <1995JA7017, 1995JA12593>, synthesized by a palladium-catalyzed cross-coupling reaction, act as very sensitive fluorescence chemosensors by forming in the presence of paraquat side-chain polypseudorotaxanes. Binding of the analyte causes a quenching of the fluorescence associated with the polymer backbone much more pronounced than that observed for a model monomeric species.

Of the various primary conjugated polymer backbones, such as poly (p-phenylenevinylene)s, poly(thiophene)s, poly(phenyleneethynylene), etc., [42] poly(fluorene) and related structures have been widely used in biological... 

Very recently, microporous poly(p-phenylene) and poly(phenyleneethynylene) materials based on a spirobifluorene building block were reported (BET surface areas 450-510 m g ) [63]. These interesting materials exploit two of the aforementioned design strategies - that is, spiro linkers (as found in soluble PIMs [9, 10], Sect. 2.2.1) combined with rigid phenylene [24] and phenylene ethynylene...

Aida and coworkers synthesized water-soluble poly(phenyleneethynylene) wrapped with poly(benzyl ether) dendrimer frameworks bearing negatively exterior surfaces, as a photosensitizer [130]. The wrapping of the conjugated backbone suppressed self-quenching of the excited state. The negatively charged surface incorporated to form a spatially separated donor-...
