Photochromic Diarylethene-Containing Coordination Compounds And The Production Thereof
- Summary
- Diarylethene-Containing Ligands And Their Coordination Compounds Are Described. The Ligands Display Photochromism With Uv Excitation, While The Coordination Compounds Display Photochromism With Both Excitation In The Uv Region And Excitation Into Lower Energy Absorption Bands Characteristic Of The Coordination Compounds, Through Which The Excitation Wavelengths For The Photocyclization Can Be Extended From Lambda<=340 Nm To Wavelengths Beyond 470 Nm. Switching Of The Luminescence Properties Of The Compounds Has Also Been Achieved Through Photochromic Reactions.
