Synthesis and photophysical properties of two Platinum(II) diimine diacetylides - A new approach for fluorescent two-photon absorption materials from organometallics

► Two new Platinum(II) diimine diacetylides were designed and synthesized. ► One compound exhibited orange-red fluorescence with relatively high fluorescence quantum yield and strong two-photon absorption cross-section. ► The influence of metal on the electronic structure and property was investigated.
