“…Considering the strong coordination abilities and various coordination modes of 4,5-imidazoledicarboxylic acid [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] and its 2-position substituent derivatives, such as 2methyl-1H-imidazole-4,5-dicarboxylic acid (H 3 MIDC) [18][19][20], 2-ethyl-1H-imidazole-4,5-dicarboxylic acid [21,22], 2-propyl-1H-imidazole-4,5-dicarboxylic acid [23][24][25], 2-(hydroxymethyl)-1H-imidazole-4,5-dicarboxylic acid [26], 2-pyridyl-1H-imidazole-4, 5-dicarboxylic acid [27,28], and 2-phenyl-1H-imidazole-4,5-dicarboxylic acid [29][30][31], they have been used to prepare many metal-organic frameworks (MOFs) with intriguing structures and properties. Most of the reported imidazole dicarboxylatebased MOFs are of transition metal ions and MOFS of lanthanides are limited [4,6,23].…”
