Abstract

Abstract : A highly connected (5, 5, 18)-c trinodal MOF featuring a 3D diamondoid inorganic connectivity was synthesized. Tunable color and white light emission can be achieved by inclusion of Eu 3+ into the framework. Abstract : A new heterometallic MOF, namely [Cd2 K4 (2, 3-PDC)4 ] (1 ) (2, 3-H2 PDC = 2, 3-pyridine dicarboxylic acid), has been successfully synthesized from Cd 2+ and K + salts with 2, 3-H2 PDC under the solvothermal conditions. Single crystal X-ray diffraction studies reveal that1 is a three-dimensional, highly connected trinodal (5, 5, 18)-c net. Compound1 features a rare 3D diamondoid Cd(ii )–K(i ) inorganic connectivity constructed by a {Cd2 K4 } cluster. The K + ion in the structure functions not only as a charge balancer but also as a connector in the construction of MOF. Tunable blue-green to white luminescence of1 was achieved by variation of the excitation wavelength and the inclusion amount of Eu 3+ ions in the host framework of1 .
