Ionic organic cage-encapsulating phase-transferable metal clusters

Abstract

A phase-transferrable metal cluster (MC) in an ionic organic cage serving as a recyclable and reaction-switchable catalyst is presented.

Accelerating Crystallization of Open Organic Materials by Poly(ionic liquid)s

“…This discovery starts with synthesis of CC3R, aprototypical porous organic [4+ +6] cycloimine.I tw as synthesized first by Coopersgroup, [2a] and is useful in fields of gas storage and separation, catalysis,a nd so on. [15] Thes tate-of-the-art synthesis of CC3R at room temperature requires ap rolonged time to yield well-shaped micrometer-sized single crystals in the presence of an acid (CF 3 COOH) to catalyze the imine bond formation. To speed up this synthesis,i no ur initial experiments CC3R was prepared at room temperature by condensation of 8mgo f( R,R)-1,2-diaminocyclohexane (DACH) and 8mgo f1 ,3,5-benzenetricarbaldehyde (BTA) in the presence of 25 mg of a1 ,2,4-triazolium PIL, poly(4hexyl-1-vinyl-1,2,4-triazolium iodide) (denoted as Ptriaz, Figure 2a,i i) in 0.7 mL of chloroform ( Figure 1a).…”

Selective Separation of Polyaromatic Hydrocarbons by Phase Transfer of Coordination Cages

“…25,26 Porous organic cages have also been developed for the selective separation of xylene isomers, 27 noble gases, 28 and chiral molecules. 28 Our group has recently focused on the use of phase transfer 29−35 of coordination cages 36−48 and their molecular cargoes as a new strategy aiming to address practical separation problems. 49…”
