The preparation and study of alkylated phosphazenes
… yields of mono- and di-alkylated chlorocyclotriphosphazenes. This method is limited in that higher substitution products can not be obtained. The reaction of trimethylaluminum (TMA) with (N₃P₃Cl₆) was examined and found to yield the fully substituted hexamethylcyclotriphosphazene (N₃P₃(CH₃)₆) in …

Determination of High Mass, Low Intensity and Transient Mass Spectra by Computer
… proposal of hexakis(multifluoroalkoxy)cyclotriphosphazenes as standards. The phosphazenes tend to give only molecular ions in the FI/FD mode. Their peaks' negative mass defects rarely interfere with sample peaks at high or low resolution while their volatility at low temperatures, even for …

Novel Host Materials for Blue Phosphorescent Organic Light-Emitting Diodes
… approach, the class of low molecular weight phosphazenes, which is less described in the context of OLED-materials, was chosen as hosts for blue phosphorescent emitters. As a common characteristic all host materials consist of a six-membered ring of alternating phosphorus and nitrogen atoms. …

Understanding and Preventing the Degradation of Silicon as a Lithium Ion Battery Anode
… overcome it using electrolyte additives and poly(phosphazenes) as artificial SEIs. Chapter 1 outlines the need for LIBs and their functionality and introduces silicon as an anode material and the chemistry of (poly)phosphazenes. Chapter 2 describes the relevant techniques such as scanning electron …

Polarity Inversion in Silicon and Phosphorus Compounds
… constrained phosphine imides (i.e., phosphazenes) will be discussed. By imposition of non-VSEPR geometries through cyclic constraint, these vicinal ambiphilic P(V) compounds readily undergo unorthodox 1,2-addition reactions as a function of increased electrophilic character at the …
