Hydrogen-bond organized 2D metal-organic microsheets:direct ultralong phosphorescence and color-tunable optical waveguides
文献摘要：
Ultralong phosphorescent materials have numerous applications across biological imaging,light-emitting devices,X-ray detection and anti-counterfeiting.Triplet-state molecular phosphorescence typ-ically accompanies the singlet-state fluorescence during photoluminescence,and it is still difficult to achieve direct triplet photoemission as ultralong room temperature phosphorescence(RTP).Here,we have designed Zn-IMDC(IMDC,4,5-imidazoledicarboxylic acid)and Cd-IMDC,two-dimensional(2D)hydrogen-bond organized metal-organic crystalline microsheets that exhibit rarely direct ultralong RTP upon UV excitation,benefiting from the appropriate heavy-atom effect and multiple triplet energy levels.The excitation-dependent and thermally stimulated ultralong phosphorescence endow the metal-organic systems great opportunities for information safety application and temperature-gated afterglow emission.The well-defined 2D microsheets present color-tunable and anisotropic optical waveguides under different excitation and temperature conditions,providing an effective way to obtain intelligent RTP-based photonic systems at the micro-and nano-scales.
