Spectroscopic investigations of pyrene butanol encapsulated in C-hexylpyrogallol[4]arene nanocapsules

Aqueous solubilization of hydrophobic supramolecular metal–organic nanocapsules

“…[13][14][15][16][17] The encapsulation sites available within these PgC n M-based nanocapsules render them captivating candidates for practical applications such as drug delivery. 13,[18][19][20][21][22] These macrocycles, PgCs, have been shown to encapsulate several ourophore probes, such as pyrene, pyrene butanol, ADMA, pentacene and acanapthene. [18][19][20][21][22] Structurally similar to PgC n , resorcin [4]arenes (RsC n ) have also been shown to encapsulate insulin monomer as a guest moiety.…”

Encapsulation of Acenaphthene within C‐Propan‐3‐ol‐pyrogallol[4]arene Dimeric Nanocapsules

“…[18][19][20][21][22][23] These hexameric nanocapsules were shown to act as a host to multiple guest molecules, mainly pyrene derivatives. The dimeric nanocapsules that are the focus of this work are seamed together with crystallisation solvent molecules (methanol) and are capable of encapsulating a single acenaphthene molecule.Investigation into the behaviour of these entities in solution has been fairly limited, although our previous reports [24][25][26][27] have provided insight through the use of molecular spectroscopy techniques, particularly steady-state and dynamic fluorescence measurements. This ground-breaking work illustrated the potential of the PgC n nanocapsules for wide-ranging applications including molecular transport, sorting and catalysis.…”

“…[20,[23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] Previous studies of pyrene butyric acid (PBA) and pyrene butanol (PBOH) encapsulated within the hexameric C-hexylpyrogallol[4]arene (PgC 6 ) nanocapsules remarkably showed that the guest remained entrapped within the hexameric nanocapsules in solution for both systems. [24,25] Single-crystal X-ray crystallographic data revealed that the nanocapsules were mainly doubly occupied by the guest. The fluorophores inside the cavity were separated by sandwiched assembly solvent, acetonitrile.…”

mPW1PW91 Calculated Structures and IR Spectra of the Conformational Stereoisomers of C-Cyanophenyl Pyrogallol[4]arene

“…[13][14][15][16][17][18][19][20][21][22][23][24] In particular, pyrogallol [4]arenes have drawn much attention since their emergence as new hydrogen-bonded dimeric and hexameric molecular receptors. [24][25][26][27][28] Many of the dimers are comprised of monomers seamed together, either directly or via hydrogen bond donor/acceptor solvent molecules. [29][30][31][32][33] The hexameric pyrogallol [4]arene spheroidal structures are held together by hydrogen bonding between the monomers.…”
