title: Two blue-light excitable yellow-emitting LMOF phosphors constructed by triangular tri(4-pyridylphenyl)amine.
abstract: Two luminescent metal-organic-frameworks (LMOFs) constructed by a molecular chromophore [tri(4-pyridylphenyl)amine] (tppa) were synthesized by solvothermal reactions and characterized by single crystal and powder X-ray diffraction, thermogravimetric analysis, optical diffuse reflection, photoluminescence spectroscopy, and internal quantum yield measurements. Both compound 1 [Zn(tppa)(ndc)·(DMF)4] and compound 2 [Zn4(tppa)2(sdc)3(NO3)2·(DMF)4·(ACN)2] (ndc = 2,6-naphthalenedicarboxylic acid, sdc = (E)-4,4'-(ethene-1,2-diyl)dibenzoic acid, DMF = dimethylformamide, ACN = acetonitrile) exhibit intense yellow emission under blue light (455 nm) excitation. The Commission International de I'Eclairage (CIE) coordinates of 1 (0.42, 0.53) and 2 (0.42, 0.54) are close to that of YAG:Ce3+(0.41, 0.55) (λex= 455 nm). The two phosphor materials show promise for use in phosphor-converted white LEDs (PC-WLEDs).
