Poly[(9-anthrylmethyl methacrylate)-co-(methyl methacrylate)]
through RAFT with different AnMMA ratios, resulting in tunable
inter-chromophore distances. These polymers can serve as
emitters, with PtOEP as sensitizer, in TTA-UC systems. TTA-UC
intensity of the Poly(AnMMA-co-MMA)/PtOEP mixtures
displays interesting dependence on the AnMMA ratio in the
polymer. It increases initially with increasing AnMMA ratio, and
decreases after the AnMMA ratio is above an optimal value,
ultimately disappearing when AnMMA ratio reaches 40%.

10 Interactions between chromophores on the same polymer chain
play the key role in affecting the TTA-UC intensity in these
systems. It is critical to minimize intra-chain chromophore
quenching in order to achieve high UC intensity.
