[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Supramolecular chemistry is the study of how to form complexes through molecular self-assembly and intermolecular bonding. Our research group has been doing a lot supramolecular research based on macrocycles such as calixarenes, pyrogallolarenes and resorcinarens. This research is interested in formation of novel C-alkyresorcin[n]arene( n=4,6) based cocrystals. The basic plan is to design and synthesize cocrystals, then analyze the crystal structure via single crystal X-ray diffraction technique, and determine if the novel cocrystal has the ability to absorb gases such as carbon dioxide and nitrogen. Chapter two is about the cocrystallization of six different C-alkylresorcin[4]arene according the chain length and guest molecule 1-(2-pyridylazo)-2-naphthol( PAN) in four solvent systems. Five successfully synthesized cocrystals' structure and synthesis are discussed. Chapter three talks how to use cocrystallization as a separation method to separate C-ethylresocin[6]arene from C-ethylresorcin[4]arene. Three noval C-ethylresorcin[6]arene based cocrystals from three different solvents are discussed. Chapter four investigates the cocrystallization between C-ethylresorcin[n]arene (n=4, 6) with 4, 4'-bipyridine. It discusses how solvent and component concentration affect such cocrystallization. Chapter five uses cocrystal formed from C-ethylresorcin[6]arene and 1,2-bis(4-pyridyl)ethane in acetone as the gas sorption candidate to test its ability to absorb gases after solvent removal. The conditions of removing solvents and gas sorption results are discussed.

In this study, we successfully synthesized two types of meso/microporous carbon materials through the carbonization and potassium hydroxide (KOH) activation for two different kinds of hyper-crosslinked polymers of TPE-CPOP1 and TPE-CPOP2, which were synthesized by using Friedel–Crafts reaction of tetraphenylethene (TPE) monomer with or without cyanuric chloride in the presence of AlCl3 as a catalyst. The resultant porous carbon materials exhibited the high specific area (up to 1100 m2 g−1), total pore volume, good thermal stability, and amorphous character based on thermogravimetric (TGA), N2 adsoprtion/desorption, and powder X-ray diffraction (PXRD) analyses. The as-prepared TPE-CPOP1 after thermal treatment at 800 °C (TPE-CPOP1-800) displayed excellent CO2 uptake performance (1.74 mmol g−1 at 298 K and 3.19 mmol g−1 at 273 K). Furthermore, this material possesses a high specific capacitance of 453 F g−1 at 5 mV s−1 comparable to others porous carbon materials with excellent columbic efficiencies for 10,000 cycle at 20 A g−1.
