A series of platinum (II) acetylide complexes containing p-phenylenevinylene and moieties end-capped with triphenylamine groups have been incorporated into poly (methyl methacrylate)(PMMA) monoliths for optical power limiting applications. The one-and two- photon photophysical properties were investigated and compared to the photophysical properties in THF. The absolute two-photon absorption cross-section values for the ...
