Oligothiophene

An interesting application of the Paal thiophene synthesis was documented for the synthesis of a polystyrene-oligothiophene-polystyrene copolymer. In the Stetter reaction of aldehyde 13 and P-dimethylaminoketone 14, in situ generation of the a,p-unsaturated ketone preceded nucleophilic 1,4-conjugate addition by the acyl anion... [Pg.210]

Linear monodisperse tt-conjugated oligopyrroles and oligothiophenes as model compounds for polymers 99AG(E)1350. [Pg.219]

The chemical scheme of oligothiophenes (wT, where rt stands for the number of thiophene units) is shown in Figure 14-14. [Pg.259]

Mobilities up to 1.5 cm2 V-1 s 1 have been obtained for films deposited on hcale substrates [94—96]. As in the case of oligothiophenes, this has been attributed to a highly ordered morphology, close to that of a single crystal [94]. However, high values are only obtained under very acute deposition parameters (in particular an opti... [Pg.261]

In addition, highly enantioselective nitroaldol reactions were performed by Bandini et al. by using a new class of C2-symmetric oligothiophene ligands, in 2007. Thus, associated to copper, these C2-symmetric bis(amino) ligands allowed the synthesis of a wide range of enantiomerically enriched nitroalcohols... [Pg.319]

Since thiophenes are regarded as being good substructures for organic electronic materials, phosphorylthiophenes are taken as reference compounds for thiophene based materials [45] and phosphorylthiophenes such as 16 are employed as synthetic intermediates for phosphoryl substituted organic electronic materials such as oligothiophenes or thienylene bridged donors (Scheme 26) [46],... [Pg.27]

Amino pyrimidine-terminated oligothiophenes such as 78 were components of donor-acceptor photovoltaic devices <06T2050>. [Pg.405]

A recent publication by the group of Barbarella has disclosed the rapid preparation of poorly soluble unsubstituted and modified a-quinque- and sexithiophenes by the extensive use of bromination/iodination steps and microwave-assisted Suzuki and Sonogashira cross-couplings (Scheme 6.16) [42]. Suzuki reactions were either carried out under solvent-free conditions on a strongly basic potassium fluoride/ alumina support for the synthesis of soluble oligothiophenes, or in solution phase for the preparation of the rather insoluble a-quinque- and sexithiophenes. In both cases, 5 mol% of [l,l -bis(diphenylphosphino)ferrocene]dichloropalladium(II)... [Pg.117]
