Tetraptycene derivatives: synthesis, structure and their self-assemblies in solid state.

As iptycenes of arenes are fused to a bicyclo[2.2.2]octatriene bridgehead system, there are only odd-sequenced iptycene family members, such as triptycene, pentiptycene and heptiptycene.

A three dimensional graphdiyne-like porous triptycene network for gas adsorption and separation.

Graphdiyne, an emerging carbon allotrope, has attracted many researchers devoted to the study of its synthesis and application. The utilization of graphdiyne in gas adsorption and separation has been predicted by computer simulation with many examples. In this work, the triangular basic unit of graphdiyne was introduced into a triptycene-based porous organic polymer to obtain a three dimensional graphdiyne-like porous triptycene network named G-PTN.

Switching porosity of stable triptycene-based cage solution-state assembly processes.

It is a great challenge to tune the porosity of porous materials. As most porous organic cages are soluble, solution processability can be a possible way to regulate the porosity of such materials. Herein, a triptycene-based cage (TC) is demonstrated to be stable in acid, base or boiling water.

Porous carbon from tobacco stalk for removal of organic dyes from water.

Tobacco stalk, a kind of agricultural residue, will cause environmental pollution because it contains some harmful substances such as nicotine. To realize the high-value utilization of this agricultural residue, we prepared porous carbon (TS-C) by high temperature carbonization using tobacco stalk as a precursor. It was found that TS-C displays a hierarchical pore structure and high Brunauer-Emmett-Teller (BET) surface area of 1416 m g.

Efficient alkaloid capture from water using a charged porous organic polymer.

Berberine hydrochloride (BH), an important alkaloid, can be captured from water and released in organic solution circularly by a charged porous polymer (TPB-HCP), which is hypercross-linked using the cost-effective Friedel-Crafts reaction using sodium tetraphenylborate as the monomer. With high BET surface area, hierarchical porous structure and charged characteristics, TPB-HCP displays excellent adsorption capacity for BH owing to the synergistic effects of size matching and electrostatic interaction.
