Abstract
It is for the first time found that poly(N-vinylcarbazole)(PVCz)/polystyren e (PS) blends have lower miscibility on molecular level than that of PVCz/p olyoxyethylene (PEO) blends. This is obtained from excimer fluorescence pro perties of PVCz in PVCz (9.1-100%)/PS and PVCz (9.6-100%)/PEO blends. Schem atic diagrams of phase-separated structure of the PVCz blends are proposed consistent with emission properties and phase-contrast microscopic images.
