Linear 1,4-coupled oligoanilines of defined length: Preparation and spectroscopic properties

A facile synthetic method involving SNAr coupling of 4-fluoronitrobenzene to arylamines, followed by reduction of the nitro groups, has been developed. The method allows the preparation of symmetric (NH 2/ NH2 end-capped) and asymmetric (Ph/NH2 end-capped) oligoanilines of even or odd chain lengths. The preparation of the NH2/NH2 end-capped trimer to octamer and Ph/NH2 end-capped trimer to pentamer is described. The effect of the chain length on the spectroscopic properties of the oxidized oligomers has been investigated by UV-Vis-NIR spectroscopy.

Temperature Control of Sequential Nucleation–Growth Mechanisms in Hierarchical Supramolecular Polymers

Upon cooling insolution, chiral triarylamine tris-amide unimers produce organogels by stacking into helical supramolecular polymers, which subsequently bundle into larger fibers. Interestingly, circular dichroism, vibrational circular dichroism, and AFM imaging of the chiral self-assemblies revealed that monocolumnar P-helical fibrils formed upon fast cooling, whereas bundled M-superhelical fibers formed upon slow cooling. The mechanistic study of this structural bifurcation reveals the presence of a strong memory effect, reminiscent of a complex stepwise combination of primary and secondary nucleation-growth processes. These results highlight the instrumental role of sequential self-assembly processes to control supramolecular architectures of multiple hierarchical order.

Amino surface-functionalized tris(calix[4]arene) dendrons with rigid C 3-symmetric propeller cores

Dendrons composed of three functionalized cone calix[4]arene substructures covalently bound to rigid C3-symmetric tris-anilino cores through amide linkages have been obtained by a divergent synthetic protocol involving the coupling of p-nitrocalix[4]arene butanoic acid 9 with tris(4-aminophenyl) amine (TAPA), 1,3,5-tris(4-aminophenyl)benzene (TAPB), and 2,4,6-tris(4- aminophenyl)-s-triazine (TAPT). Two different amidation procedures were used to generate the dodecanitro intermediates (through activation of acid 9 with PyBOP catalyst or transformation into its acid chloride). The final reduction to the title dodecaamino dendrons was smoothly carried out with H2 and Raney-Ni catalyst.
