PQDBP8 showed highly thermal stability (T-d = 384 degrees C, T-g = 183 degrees C), PQDBP8 showed blue fluorescence in dilute solution (lambda(max) = 449 nm) and green fluorescence in solid state (lambda(max) = 494, 540 nm) due to excimer formation. EL spectrum of PQDBP8 lies in the green region (lambda(max) = 572 nm) and PQDBP8/PVK blend film lies in the blue region(lambda(max) = 446 nm).
