Thanthapatra Bunchuay

Thanthapatra (Valentine) Bunchuay, a recipient of the Royal Thai Scholarship (2004 – 2018), graduated from Mahidol University (Thailand) with a first class honour B.Sc. degree in 2011 and M.Sc. degree in chemistry in 2014. Having finished his D.Phil.in November 2018, he is now working as associate professor in organic chemistry (supramolecular chemistry) at Mahidol University where he has started The SupraValentine Research Lab. His research focuses on synthetic supramolecular chemistry of macrocyclic molecules and investigations of their host-guest behavior via suite spectroscopic techniques. Novel macrocycles are also used as the basis of functional materials for applications in sensing, extraction and recovery, delivery, and soft materials.

要旨:

Since the pioneering work of Cram, Lehn, and Pedersen laid the foundation for supramolecular host-guest chemistry, macrocyclic motifs have been indispensable tools in molecular assembly. Their accessibility and well-established complementarity for a diverse range of guest molecules have made them central to the field. In 2008, Ogoshi and collaborators introduced a breakthrough in macrocyclic chemistry with the synthesis of a novel family of macrocycles, the pillararenes. These unique structures, named for their pillar shape, consist of cyclic oligomers (n = 5–15) of dialkylated hydroquinone monomers linked by methylene spacers at the 2,5-positions. This arrangement creates a highly symmetric and rigid cavity with exceptional properties, propelling pillararenes to prominence in supramolecular chemistry and nanomaterials. This seminar will first introduce the fundamental aspects of pillararene chemistry followed by highlight recent advances made by the SupraValentine Laboratory at MUSC, covering synthetic methodologies, host-guest interactions, molecular assemblies, and applications in nanomaterials. In the second half, the focus will turn to other innovative supramolecular host designs, emphasizing their structural diversity and applications in recognizing cations, anions, and ion pairs.
