The design embraces the specific motivation of incorporating the nitrogen-containing heterocycle viz. .phenazine in poly(phenylenevinylene) backbone. P(PHN-PV) exhibited reversible redox properties. In the field emission measurements performed on the film of P(F'HN-PV), the turn-on field was observed to be 1.93 V/mu m for the current density of 10 mu A/cm(2). The maximum current density of similar to 4.87 mA/cm(2) was achieved at the applied field of 3.84 V/mu m. The emission current showed impressive stability for 6 h at a constant current of 1 mu A (current density of about 20 mu A/cm(2)). These results emphasize the role of phenazine heterocycle with lone pair of electrons on nitrogen in lowering the oxidation onset and in turn reduction of the turn-on voltage.</p>10afield emission10aPhenazine10aPoly(phenylenevinylene)1 aChhatre, Shraddha1 aIchake, Amol1 aHarpale, Kashmira1 aPatil, Sumati1 aDeshpande, Aparna1 aMore, Mahendra1 aWadgaonkar, Prakash, P.  uhttps://library.ncl.res.in/content/phenazine-containing-polyphenylenevinylene-new-polymer-impressive-field-emission-properties
