Yang, Jingjing Trickett, Christopher A. Alahmadi, Salman B. Alshammari, Ahmad S. Yaghi, Omar M. Calcium l‑Lactate Frameworks as Naturally Degradable Carriers for Pesticides Two porous, chiral metal–organic frameworks (MOFs), Ca<sub>14</sub>(l-lactate)<sub>20</sub>(acetate)<sub>8</sub>(C<sub>2</sub>H<sub>5</sub>OH)­(H<sub>2</sub>O) (MOF-1201) and Ca<sub>6</sub>(l-lactate)<sub>3</sub>(acetate)<sub>9</sub>(H<sub>2</sub>O) (MOF-1203), are constructed from Ca<sup>2+</sup> ions and l-lactate [CH<sub>3</sub>CH­(OH)­COO<sup>–</sup>], where Ca<sup>2+</sup> ions are bridged by the carboxylate and hydroxyl groups of lactate and the carboxylate group of acetate to give a three-dimensional arrangement of Ca­(−COO, −OH) polyhedra supporting one-dimensional pores with apertures and internal diameters of 7.8 and 9.6 Å (MOF-1201) and 4.6 and 5.6 Å (MOF-1203), respectively. These MOFs represent the first examples of extended porous structures based on Ca<sup>2+</sup> and lactate. They show permanent porosity of 430 and 160 m<sup>2</sup> g<sup>–1</sup>, respectively, and can encapsulate an agriculturally important fumigant, <i>cis</i>-1,3-dichloropropene. MOF-1201 shows a 100 times lower release rate compared with liquid <i>cis</i>-1,3-dichloropropene under the same test conditions (25 °C, air flow rate of 1 cm<sup>3</sup> min<sup>–1</sup>). The hydrolysis of MOF-1201 in water makes it the first example of a degradable porous solid carrier for such fumigants. OH;H 2 O;CH;air flow rate;acetate;MOF -1201;l-lactate 2017-06-04
