Photon-based synthesis

Photon-based synthesis could provide an avenue to preserve the structure of miCToemulsions (in the chemical reduction method, the introduction of the reducing agent into the water core from outside may damage the structure of microemulsions). A photochemically induced metal nanoparticles synthesis in the water-in-scC02 microemulsion involves microemulsion formation followed by metal ion reduction through absorption of incident light by microemulsion which contains the reactants precursors [43]. 

One may find many examples and detailed descriptions of template-based synthesis of nanomaterials including photonic crystals in some review papers (Martin, 1996 Hulteen, 1997 Huezko, 2000 Stein, 2001). 

New natural polymers based on synthesis from renewable resources, improved recyclability based on retrosynthesis to reusable precursors, and molecular suicide switches to initiate biodegradation on demand are the exciting areas in polymer science. In the area of biomolecular materials, new materials for implants with improved durability and biocompatibility, light-harvesting materials based on biomimicry of photosynthetic systems, and biosensors for analysis and artificial enzymes for bioremediation will present the breakthrough opportunities. Finally, in the field of electronics and photonics, the new challenges are molecular switches, transistors, and other electronic components molecular photoad-dressable memory devices and ferroelectrics and ferromagnets based on nonmetals.

The successful assembly of organic compounds on a solid support represents only part of the challenge in SPOS. After completion of synthetic sequence, the compounds must be cleaved from linkers attached to polymer by a chemical or photochemical reaction, for example, treatment of a polymer-bound compound with acids, bases, nucleophiles, redox reagents, and even photons. Acid-labile linker and amine-cleavable Marshall linker are two major classes of hnkers used in combinatorial synthesis. 

Carboxylates With the aim of developing highly luminescent Er111 complexes for advanced photonic applications, some of the research concentrates on the synthesis of new ligands, based on simple molecular frameworks such as alkyl chains or benzene rings fitted with carboxylate groups for coordination to the lanthanide ions. For instance, the photophys-...
