The development of small molecules that can recognize specific RNA secondary and tertiary structures is currently an important research topic for developing tools to modulate gene expression and therapeutic drugs. Expanded CUG trinucleotide repeats, known as toxic RNA, capture the splicing factor MBNL1 and are causative of neurological disorder myotonic dystrophy type 1 (DM1). Herein, the rational molecular design, synthesis, and binding analysis of 2,9-diaminoalkyl-substituted 1,10-phenanthroline (DAP), which bound to CUG trinucleotide repeats, is described. The results of melting temperature (Tm) analyses, surface plasmon resonance (SPR) assay, and electrospray spray ionization time-of-flight (ESI-TOF) mass spectrometry showed that DAP bound to r(CUG)9but not to r(CAG)9and r(CGG)9. The dual luciferase assay clearly indicated DAP bound to the r(CUG)nrepeat by affecting the translation in vitro.

Cobalt complexes are well-known catalysts for photocatalytic proton reduction in water. Macrocyclic tetrapyridyl ligands (pyrphyrins) and their CoII complexes emerged in this context as a highly efficient class of H2 evolution catalysts. On the basis of this framework, a new macrocyclic CoII complex consisting of two keto-bridged bipyridyl units (Co diketo-pyrphyrin) is presented. The complex is synthesized along a convenient route, is well soluble in water, and shows high activity as a water reduction catalyst (WRC). In an aqueous system containing [Ru(bpy)3]Cl2 as a photosensitizer and NaAscO as a sacrificial electron donor, turnover numbers (TONs) of 2500 H2/Co were achieved. Catalysis is terminated by a limited electron supply and decomposition of the photosensitizer but not of the WRC, highlighting the distinct stability of Co diketo-pyrphyrin.

Pyridine and oligopyridines bearing halide or triflate groups react smoothly with CO (1 atm) and n-butanol in the presence of a tertiary amine and a catalytic amount of bis(triphenylphosphine)palladium dichloride to afford the corresponding esters. When ethanol and a disubstituted substrate are used under milder conditions, selective mono-carboalkoxylation occurs. Amidation is effected using a primary amine as nucleophile.

Reaction of 6,6?-dibromo-2,2?-bipyridine with phenylphosphine under palladium-promoted cross-coupling conditions provides a variety of linear oligomers bearing two reactive bromo substituents as well as a cyclic dimer, characterized by X-ray crystallography, in which the bipyridine units are constrained to a cis configuration by two phenylphosphine oxide bridges. Derivatives of the linear species containing both carboxylate and phosphonate substituents are readily obtained.

Utilizing an induced-fit model and taking advantage of rotatable acetylenic C(sp)-C(sp2) bonds, we disclose the synthesis and solid-state structures of a series of conformationally diverse bis-sulfonamide arylethynyl receptors using either pyridine, 2,2?-bipyridine, or thiophene as the core aryl group. Whereas the bipyridine and thiophene structures do not appear to bind guests in the solid state, the pyridine receptors form 2 + 2 dimers with water molecules, two halides, or one of each, depending on the protonation state of the pyridine nitrogen atom. Isolation of a related bis-sulfonimide derivative demonstrates the importance of the sulfonamide N-H hydrogen bonds in dimer formation. The pyridine receptors form monomeric structures with larger guests such as BF4- or HSO4-, where the sulfonamide arms rotate to the side opposite the pyridine N atom.

In this study, we show that 1) different isomers of the same mononuclear iron(II) complex give materials with different spin-crossover (hereafter SCO) properties, and 2) minor modifications of the bapbpy (bapbpy=N6,N6?- di(pyridin-2-yl)-2,2?-bipyridine-6,6?-diamine) ligand allows SCO to be obtained near room temperature. We also provide a qualitative model to understand the link between the structure of bapbpy-based ligands and the SCO properties of their iron(II) compounds. Thus, seven new trans-[Fe{R 2(bapbpy)}(NCS)2] compounds were prepared, in which the R2bapbpy ligand bears picoline (9-12), quin-2-oline (13), isoquin-3-oline (14), or isoquin-1-oline (15) substituents. From this series, three compounds (12, 14, and 15) have SCO properties, one of which (15) occurs at 288 K. The crystal structures of compounds 11, 12, and 15 show that the intermolecular interactions in these materials are similar to those found in the parent compound [Fe(bapbpy)(NCS)2] (1), in which each iron complex interacts with its neighbors through weak N-H…S hydrogen bonding and pi-pi stacking. For compounds 12 and 15, hindering groups located near the N-H bridges weaken the N-S intermolecular interactions, which is correlated to non-cooperative SCO. For compound 14, the substitution is further away from the N-H bridges, and the SCO remains cooperative as in 1 with a hysteresis cycle. Optical microscopy photographs show the strikingly different spatio-temporal evolution of the phase transition in the noncooperative SCO compound 12 relative to that found in 1. Heat-capacity measurements were made for compounds 1, 12, 14, and 15 and fitted to the Sorai domain model. The number n of like-spin SCO centers per interacting domain, which is related to the cooperativity of the spin transition, was found high for compounds 1 and 14 and low for compounds 12 and 15. Finally, we found that although both pairs of compounds 11/12 and 14/15 are pairs of isomers their SCO properties are surprisingly different.
