“…Williams and co-workers recently used FTIR spectroscopy to quantitatively assess the azide/triazole surface coverage on particles over the course of a cycloaddition reaction. FTIR was chosen because the technique is highly sensitive and is able to examine molecules that remain attached to the particle surface [34]. As shown in Fig.…”

“…1‐Azidooctane (4) was prepared following a literature procedure for the analogous C12 compound . NaN 3 (12.1 g, 0.18 mol) was stirred in 80 mL of dried dimethyl sulfoxide (DMSO) for 1 h whereupon 1‐bromooctane (20 g, 0.1 mol) in tetrahydrofuran (THF, 300 mL) was added.…”

Dialkynes are grafted onto hydrogen‐passivated silicon wafers, porous silicon, and silicon nanowires via thermally induced hydrosilylation followed by surface functionalization via azide alkyne cycloaddition. The surfaces are characterized with Fourier transform infrared spectroscopy (FTIR) and electrochemical measurements that indicate a correlation between the quality of the organic layer and the morphology of the substrate. After the initial hydrosilylation reaction, the amount of accessible surface bonded alkynes is observed to be substantially lower on porous, irregular surfaces compared to flat wafers and well‐defined vertically aligned silicon nanowire arrays, thus precluding an effective subsequent azide‐alkyne cycloaddition on porous silicon.

“…[175,176] By the synthesis of block copolymers, the desirable properties of two different types of polymers can often be combined. [177] PNIPAm can be crosslinked to form a hydrogel. Typical crosslinkers are N,N ′methylene-bis-acrylamide and N,N ′ -cystamine-bis-acrylamide.…”

“…[174] Boisselier et al [122] (2008) have shown that it is possible to perform this reaction on the surface of AuNPs, which are decorated with ligands bearing azide groups. [175] Using specific conditions (a 1:1mixture of water and THF as solvent, stoichiometric copper sulfate and sodium ascorbate in an inert atmosphere at 20°C), the problems caused by the presence of copper in performing this reaction on colloidal gold [176,177] can be overcome. As a potential coupling partner for azide-decorated surfaces, RAFT agent ρ − − − -6 , bearing the complementary alkyne group at its R-group, was designed.…”

The series "Springer Theses" brings together a selection of the very best Ph.D. theses from around the world and across the physical sciences. Nominated and endorsed by two recognized specialists, each published volume has been selected for its scientific excellence and the high impact of its contents for the pertinent field of research. For greater accessibility to non-specialists, the published versions include an extended introduction, as well as a foreword by the student's supervisor explaining the special relevance of the work for the field. As a whole, the series will provide a valuable resource both for newcomers to the research fields described, and for other scientists seeking detailed background information on special questions. Finally, it provides an accredited documentation of the valuable contributions made by today's younger generation of scientists.Theses are accepted into the series by invited nomination only and must fulfill all of the following criteria • They must be written in good English.• The topic should fall within the confines of Chemistry, Physics, Earth Sciences, Engineering and related interdisciplinary fields such as Materials, Nanoscience, Chemical Engineering, Complex Systems and Biophysics.
