Temperature Dependence of Triplet–Triplet Annihilation Upconversion in Phospholipid Membranes

[Image: see text] Understanding the temperature dependency of triplet–triplet annihilation upconversion (TTA-UC) is important for optimizing biological applications of upconversion. Here the temperature dependency of red-to-blue TTA-UC is reported in a variety of neutral PEGylated phospholipid lipos...

description [Image: see text] Understanding the temperature dependency of triplet–triplet annihilation upconversion (TTA-UC) is important for optimizing biological applications of upconversion. Here the temperature dependency of red-to-blue TTA-UC is reported in a variety of neutral PEGylated phospholipid liposomes. In these systems a delicate balance between lateral diffusion rate of the dyes, annihilator aggregation, and sensitizer self-quenching leads to a volcano plot, with the maximum upconversion intensity occurring near the main order–disorder transition temperature of the lipid membrane.
