The two-photon absorption properties of bisfluorene dendrimers are investigated in both the nanosecond and femtosecond regime. By substituting different dendrons onto same chromophore (see figure), we examine effect on spectrum magnitude absorption. As these have high photoluminescence quantum yields, then proceed to make pumped dendrimer lasers.
