Site-selective hexa-hetero-functionalization of α-cyclodextrin an archetypical C6-symmetric concave cycle

Selective recognition of endocrine disruptors by fluorogenic gamma-cyclodextrin having pyrene-tosyl substituents on hetero rims.

Functionalization of α-synuclein fibrils

The propensity of peptides and proteins to form self-assembled structures has very promising applications in the development of novel nanomaterials. Under certain conditions, amyloid protein α-synuclein forms well-ordered structures - fibrils, which have proven to be valuable building blocks for bionanotechnological approaches. Herein we demonstrate the functionalization of fibrils formed by a ...

Selective functionalization of arbitrary nanowires.

We report the selective functionalization of uniform and heterostructured nanowires with self-assembled monolayers (SAMs) of (3-mercaptopropyl)trimethoxysilane (MPTMS). The wires were grown electrochemically in anodic aluminum oxide (AAO) templates. Selective deposition and removal of SAMs during nanowire growth permits the decoration of specific regions of the surface along the length of the n...

Selective functionalization of imidazoles via an iodine-copper exchange reaction.

The reaction of protected 4,5-diiodoimidazoles with (PhMe2CCH2)2CuLi regioselectively provides 5-cuprated imidazoles, which readily react with various electrophiles furnishing functionalized imidazoles in good yields; remarkably, these resulting mono-iodoimidazoles undergo again an iodine-copper exchange reaction in the presence of sensitive functional groups, like an aldehyde or a ketone.

Site-selective electronic correlation in α-plutonium metal.

An understanding of the phase diagram of elemental plutonium (Pu) must include both, the effects of the strong directional bonding and the high density of states of the Pu 5f electrons, as well as how that bonding weakens under the influence of strong electronic correlations. Here we present electronic-structure calculations of the full 16-atom per unit cell α-phase structure within the framewo...
