Synthesis, optical power limiting, and DFT calculations of triplet–triplet absorption of three novel Pt(II)-diacetylide chromophores

• Three novel rod-like Pt(II)-diacetylides have been synthesized. When subjected to intense laser light, all three compounds showed strong optical power limiting at 532 and 600 nm. DFT calculated triplet–triplet electronic excitations were found to correlate with the nonlinear absorption.
