Strikingly, distinct luminescence properties were induced by adding different PVA samples. When PVA with a higher hydrodynamic radius (Rh) and more curly structure was added, it substituted some TPEBA molecules and then twined around the surface to lock and isolate the remaining TPEBA molecules, resulting in a blueshift in the peak together with increased intensity in the emission spectrum. However, only attenuated aggregate emission was observed upon the addition of PVA with a lower Rh and more stretched chains because the arrangem
