Hydrogen-bonding-driven self-assembly nonporous adaptive crystals for the separation of benzene from BTX and cyclohexane

Keto-Adamantane-Based Macrocycle Crystalline Supramolecular Assemblies Showing Selective Vapochromism to Tetrahydrofuran

“…Thirdly, the preparation of macrocyclic molecules should be easy, and the raw materials should be cheap and easy to obtain. Adamantane and its derivatives, which have a highly symmetrical and rigid structure, can pack tightly with each other to form a lattice, and thus can easily form crystals in organic solvents; they have been widely used in the field of crystal engineering [44][45][46][47][48][49][50][51]. Building blocks 1,3-Dimethoxybenzene, that can act as π-donors, are frequently used in the construction of supramolecular macrocyclic molecules [37,52].…”

Potential of nonporous adaptive crystals for hydrocarbon separation

“…49,50 When the guest molecule is further removed, the structures of NACs return to the original nonporous states. 51 Furthermore, the guest molecule interacting with the host is more likely to be adsorbed by NACs to form a stable host-guest complex, which offers an opportunity for selective separation of the guest molecule. 52 The process of NACs adsorbing the guest molecule is often accompanied by energy change.…”

Recognition of naphthoflavones by calix[4]pyrrole[2]phenanthrene

“…The synthesis of novel macrocyclic hosts and molecular recognition is a permanent and challenging topic in supramolecular and host-guest chemistry. Although many synthetic hosts have been prepared over the past few decades, [23][24][25][26][27][28][29][30][31][32][33][34] selective recognition of naphthoflavones has been rarely reported, probably due to the large molecular size of naphthoflavones and relatively small cavity of the synthetic hosts.…”
