Abstract
Abstract A small quantity of zinc(II) tetraphenylporphyrin (ZnTPP) moieites were covalently incorporated into an amphiphilic copolymer of sodium 2-acrylamido-2-methylpropanesulfonate and N-cyclododecylmethacrylamide. The ZnTPP moieties were compartmentalized in the hydrophobic cluster of the cyclododecyl pendants in the polymer in aqueous solution, and showed a unusual blue-shifted phosphorescence due to a high energy triplet-excited (T1) state. The lifetime of the high energy T1 state was extraordinarily long: ca. 56 ms at 20 °C in aqueous solution.
