A New, Aqueous 1H NMR Shift Reagent Based on Host−Guest Molecular Recognition Principles for Organic Compound Structural Analysis: Non-covalent π−π and Hydrophobic Interactions Using a Supramolecular Host, [Cp*Rh(2‘-deoxyadenosine)]3(OTf)3
Journal of Organic Chemistry, 1998Co-Authors: Shigeyuki Nakamura, Kiyoshi Isobe, Yoshihito Watanabe, Hong Chen, Richard H. FishAbstract:We have discovered that the supramolecular host [Cp*Rh(2‘-deoxyadenosine)]3(OTf)3 (1, Cp* = η5-C5Me5, OTf = CF3SO3-) has utility as a new, aqueous 1H NMR shift reagent, via a host−guest molecular recognition process that occurs by non-covalent π−π and hydrophobic interactions, with a wide variety of H2O-soluble organic substrates. These organic compound guests that we present, to illustrate the utility of host 1 as a novel, aqueous 1H NMR shift reagent, encompass examples such as aromatic Carboxylic Acids, phenylacetic Acid (G1), 1-naphthoic Acid (G2), and 2-naphthoic Acid (G3), an Aliphatic Carboxylic Acid, cyclohexylacetic Acid (G4), as well as biological compounds, a di- and a tetrapeptide containing terminal l-tryptophan (Trp) or l-phenylalanine (Phe) groups, l-Trp-l-Phe (G5) and l-Trp-l-Met-l-Asp-l-Phe amide (G6) in the pH range 5−10.

bioorganometallic chemistry 8 the molecular recognition of aromatic and Aliphatic amino Acids and substituted aromatic and Aliphatic Carboxylic Acid guests with supramolecular η5 pentamethylcyclopentadienyl rhodium nucleobase nucleoside and nucleotid
Journal of the American Chemical Society, 1996Co-Authors: Hong Chen, Seiji Ogo, Richard H. FishAbstract:Molecular recognition, via non-covalent processes such as hydrogen bonding, π−π, and hydrophobic interactions, is an important biological phenomenon for guests, such as drugs, proteins, and other important biological molecules with, for example, host DNA/RNA. We have studied a novel molecular recognition process using guests that encompass aromatic and Aliphatic amino Acids [l-alanine, l-glutamine (l-Gln), l-histidine, l-isoleucine (l-Ile), l-leucine (l-Leu), l-phenylalanine (l-Phe), l−proline, l-tryptophan (l-Trp), l-valine (l-Val)], substituted aromatic Carboxylic Acids [o-, m-, p-aminobenzoic Acids (G1-3), benzoic Acid (G4), phenylacetic Acid (G5), p-methoxyphenylacetic Acid (G6), o-methyoxybenzoic Acid (G9), o-nitrobenzoic Acid (G10)], and Aliphatic Carboxylic Acids [cyclohexylacetic Acid (G7), 1-adamantaneCarboxylic Acid (G8)] with supramolecular, bioorganometallic hosts, (η5-pentamethylcyclopentadienyl)rhodium (Cp*Rh)−nucleobase, nucleoside, and nucleotide cyclic trimer complexes, [Cp*Rh(9-methylade...

tailoring block copolymer nanoporous thin films with acetic Acid as a small guest molecule
Polymer International, 2019Co-Authors: Alberto Alvarezfernandez, Fernando Valdesvango, J I Martin, M Velez, C Quiros, Daniel Hermidamerino, Giuseppe Portale, J M Alameda, Francisco Garcia J AlonsoAbstract:Block copolymers offer the fabrication of mesoporous thin films with distinct nanoscale structural features. In this contribution, we present the use of acetic Acid (CH3COOH) as a low-molecular-weight guest molecule to tune the supramolecular assembly of poly[styrene-block-(4-vinylpyridine)] (PS-b-P4VP), offering a versatile and straightforward method to obtain tailored nanostructured films with controlled topography and pore size. Spin-coating toluene solutions of PS-b-P4VP, with a variable amount of CH3COOH, leads to micellar thin films, where the micelles contain the Carboxylic Acid as a guest molecule. The size can be conveniently modified in these films (from 48 to 75 nm) by varying the amount of organic Acid in the starting solutions. Subsequent surface reconstruction of micellar films using ethanol leads to ring-shaped copolymer nanoporous films with modulated diameter. Controlling the micelle reconstruction process, cylindrical porous films are also obtained. Interestingly, changing the type of Aliphatic Carboxylic Acid leads to a modification of the observed film morphology from micelles to out-of-plane P4VP cylinders (or lamellae) in a PS matrix.
