In Chapter 5, photo-induced absorption is used to study the intersystem crossing from singlet to triplet states of two polyfluorenes after doped with Ir-complex. It is found that the triplet exciton lifetime of PFs is reduced by the dopants. But instead of decreasing, the population density of PF triplet exciton increases by almost one order of magnitude. The finding shows that the ISC rate can increase over 100 times due to the spin-orbital interaction with the Ir ions.
