Optical Power Limiters: Symmetric Versus Unsymmetric Platinum(II) Bis(aryleneethynylene)s with Distinct Electronic Structures for Optical Power Limiting/Optical Transparency Trade‐off Optimization (Adv. Mater. 8/2009)

Abstract

The development of symmetric and unsymmetric platinum(II) bis(acetylide)s as highly transparent optical limiters is described by Wong and co-workers. Their excited state character is governed by electronic structure, which signifi cantly affects their photophysical properties and optical power limiting (OPL) behavior. The sound OPL responses and low OPL thresholds together with their excellent optical transparency render these materials very promising candidates for practical devices for the protection of human eyes and other delicate electro-optic sensors.
