An alternative strategy to obtain silica immobilised catalysts, pioneered by Panster [23], is via the polycondensation or co-condensation of ligand functionalised alkoxysilanes. This co-condensation, later also referred to as the sol-gel process [24], appeared to be a very mild technique to immobilise catalysts and is also used for enzyme immobilisation. Several novel functional polymeric materials have been reported that enable transition metal complexation. 3-Chloropropyltrialkoxysilanes were converted into functionalised propyltrialkoxysilanes such as diphenylphosphine propyltrialkoxysilane. These compounds can be used to prepare surface modified inorganic materials. Two different routes towards these functional polymers can be envisioned (Figure 3.4). One can first prepare the metal complex and then proceed with the co-condensation reaction (route I), or one can prepare the metal complex after the... 

The recent progress surveyed in this review shows the promise that late transition metal catalysts can provide in the production of new materials. We will continue our exploration of new catalyst design for the synthesis of new functional materials with unconventional topologies. Given the unique features of late transition-metal polymerization catalysts and further improvement in catalyst stability and activity for copolymerization with polar comonomers, the future of designing novel functional polymeric materials with late-transition-metal catalysts is very promising. 

BAL chemistry is compatible with a wide range of functionalized polymeric supports, including PS, PEG-PS, and Synphase crowns. 

In conclusion, the BAL method is a novel and general strategy for solid-phase synthesis of peptides and peptide derivatives, is compatible with a wide range of functionalized polymeric supports, and is readily generalizable to other nitrogen-containing molecules.9...

This assumption stems from the fact that under the same conditions adopted to heterogenize conventional molybdenum catalysts using differently functionalized polymeric supports such as surface boronic (ref. 3) or phosphonic (ref. 4) acid groups, the Mo(VI)-fixation on a support such as (EGDA) invariably leads to a metal to acid group ratio equal to 2.0 rather than 1.0. 

Once again contrary to earlier results obtained with differently functionalized polymeric matrixes, for the same (EDGA)-Mo(VI) complex different core structures have been observed with time. Indeed, while no... 

In this section, we review in chronological order the development of the polymeric composite, fully functionalized polymeric, and the glassy molecular PR materials, respectively. For the latter two categories, we mainly focus on the progress made in our laboratory. More detailed accounts of the materials developed in other groups can be found in the references [9,10,37]. Another promising class of PR materials is PR liquid crystals, which have been reviewed by G. Wiederrecht, in Chapter 7. 

A wide variety of polymeric membranes with different barrier properties is already available, many of them in various formats and with various dedicated specifications. The ongoing development in the field is very dynamic and focused on further increasing barrier selectivities (if possible at maximum transmembrane fluxes) and/ or improving membrane stability in order to broaden the applicability. This tailoring of membrane performance is done via various routes controlled macro-molecular synthesis (with a focus on functional polymeric architectures), development of advanced polymer blends or mixed-matrix materials, preparation of novel composite membranes and selective surface modification are the most important trends. Advanced functional polymer membranes such as stimuli-responsive [54] or molecularly imprinted polymer (MIP) membranes [55] are examples of the development of another dimension in that field. On that basis, it is expected that polymeric membranes will play a major role in process intensification in many different fields.
