Knoevenagel condensation reaction is well known as modified aldol condensation with a nucleophilic addition between an aldehyde or ketone, and an active hydrogen compound in the presence of a basic catalyst, resulting in C-C bond formation. CN-PPV (cyano substituted p-phenylene vinylene) is synthesized through this reaction and we identified that CN-PPV formed thin shell at the w/o emulsion interface between base solution and oil phase containing monomers. Furthermore, we try to entrap QAPS (quasi-amorphous photonic solution) in CN-PPV thin shell and introduce microfluidics on-chip fabrication process. Because CN-PPV has electrical conductivity, we expect that unusual phenomena and optical property contrary to insulating shell microcapsules when apply electric field to CN-PPV thin shell containing QAPS in double emulsion core part. Consequentially, these electrical conductive double emulsion can be applicated in sensors, displays and so on. |
