Paper Abstract

In this paper we report measurements of the photophysical behavior of poly(p-pyridine) (PPY), including thin film absolute photoluminescence quantum yield, photoluminescence properties of solid, solution and solid-solution states, electroluminescence and nanosecond time-resolved luminescence. The influence of vacuum and air on the quantum yield of the PPY is also reported. We find a significant decay of the efficiency under vacuum whereas it is very stable in air. The role of aggregate versus excimer will be discussed and also it will be demonstrated that with appropriate fabrication conditions, good single layer PPY light emitting diodes can be fabricated.
