A green, solvent-free one-pot synthesis of disubstituted quinolines via A3-coupling using 1 mol% fecl3

A simple and green route towards disubstituted quinolines via A3-coupling using 1 mol% FeCl3 is described. Using this approach, the above-mentioned derivatives were synthesized in moderate to good yields (45-95%) under solvent-free, microwave conditions. Preliminary investigations have indicated that a further decrease in catalyst amount is possible with a satisfactory yield still observed.

ORGANIC LIGHT EMITTING DEVICE WITH THERMALLY ACTIVATED DELAYED FLUORESCENT LIGHT EMITTING MATERIAL

The present disclosure is directed to organic electroluminescent devices comprising thermally activated emission material(s) in an emission layer. The present disclosure is also directed to compounds capable of providing thermally activated delayed fluorescence, and to emission layers comprising at least one of the compounds. The compounds may be used in organic layers such as emission layers of an organic electroluminescence device such as fluorescent OLEDs.

Organic reactions in water: A distinct approach for the synthesis of quinoline derivatives starting directly from nitroarenes

Three-component reactions of nitroarenes, aldehydes, and phenylacetylene in the presence of indium in dilute hydrochloric acid produce the corresponding quinoline derivatives under reflux. The conversion in this one-pot synthesis involves the following steps: (i) reduction of the nitroarenes to anilines, (ii) coupling of the anilines, aldehydes, and phenylacetylene, (iii) cyclization of the resulting species, and (iv) dehydrogenation of the cyclic intermediates. Several new quinolines have been prepared. Georg Thieme Verlag Stuttgart · New York.

Synthesis and photophysics of new donor-acceptor copolymers based on fluorene and phenylquinolines

The synthesis and photophysics of two new donor-acceptor conjugated A-B type copolymers based on conjugated 2,6-disubstitued-4-phenyl-quinoline and 2-substitued-4-phenyl-quinoline, and 9,9-dialkyl-fluorene linked through the 1,4 and 1,3,5 phenyl rings via the Friedlnder condensation and Suzuki coupling reaction are presented. The band gap energy of the polymers 1 and 2 measured from the thin films were 430nm and 380nm corresponding to 2.88eV and 3.26eV, respectively. The photoluminescence (PL) spectra of the thin films of the polymers 1 and 2 showed maximum peaks at 427 and 397nm corresponding to the deep blue and UV ranges respectively. The red shift of the polymer 1 relative to the polymer 2 can be accounted for by the increased conjugation length because the quinoline unit is oriented to include the phenyl ring in the backbone of polymer 1. Both polymers have similar trends of irreversible oxidation. The ionization energy of polymers 1 and 2 were measured by cyclic voltammetry (CV) and were found to be 5.60 and 5.65eV, respectively.

Microwave enhanced solvent-free synthesis of a library of quinoline derivatives

A minilibrary of 12 quinoline derivatives was synthesized in the presence of 0.1-0.5 equiv. of diphenylphosphate without any solvents. Each compound was obtained with high yield in 4 min of microwave irradiation.
