Five dioxynaphthalene[38]‐crown‐10 (DNP38C10) macrocycles bearing one, two, three, or four allyl moieties have been synthesized and their ability to spontaneously self‐assemble with methyl viologen to form [2]pseudorotaxanes has been evaluated. Association constants between methyl viologen and several of the allyl‐functionalized DNP38C10 macrocycles are found to be comparable to that of methyl viologen

Novel photosensitive azopolymer brushes were synthesized via surface initiated atom transfer radical polymerization using initiator self‐assembled on Au surface. The chemical structures of azobenzene derivatives were confirmed by Fourier transform infrared spectroscopy (FTIR) and nuclearmagneticresonance spectroscopy (NMR).

The convenient synthesis of nano-building blocks with strategically placed functional groups constitutes a fundamental challenge in nano-science. Here, we describe the facile preparation of a library of mono- and di-functional (containing three isomers) polyhedral oligomeric silsesquioxane (POSS) building blocks with different symmetries (C3v, C2v, and D3d) using thiol-ene chemistry. The method is

modifications of cyclic titanium-oxo cluster: We report an efficient thiol-Michael addition approach for the precise modifications of cyclic titanium-oxo cluster (CTOC). This approach can afford high yields of fully functionalized CTOCs, which provides a powerful platform for achieving versatilefunctionalization of precise transition metal clusters and further applications.
Disclosed is a method of preparing a modified halogenated polymer surface, comprising the steps of (a) activating the surface by modification with a polymerisation initiator by (a
