摘要

This report presents preliminary optical limiting and spectroscopic characterization of dendrimer capped Pt-ethynyls. Preliminary OPL and spectroscopic characterization revealed that these have better OPL properties than the non-capped analogue. The excited state properties in terms of luminescence for emission at ca 400 nm and 525 nm is in the ns and us range, respectively. The site isolation provided by the dendrimer capping also give rise to strong phosphorescence involving the same emission bands near 525 nm. The decay time for this was found to be in the range 0.2 ms, considerably longer than for other similar Pt-complexes, and we tentatively assign this to a site-isolation effect that prevents quenching of the triplete state. It was shown how the dendron capping also makes it feasible to blend the dye with e.g. MMA monomers and carry out polymerization to obtain a solid OPL device with good performance.
