Transition Metals in Polymeric π‐Conjugated Organic Frameworks

Ground and excited state communication within a ruthenium containing benzimidazole metallopolymer

“…4,5 In particular, benzimidazole polymers are attractive since metal complexes can be coordinated to the polymer backbone opening up the possibility of site-to-site electron hopping as well as electron transfer mediated by the polymer backbone 30 itself. 6,7,8,9,10,11,12 These conjugated metallopolymers are attracting increasing attention because of their potentially widespread applications, 13,14,15,16,17,18 and significant attention has been paid to polymers containing poly(pyridyl) complexes of 35 ruthenium(II) and osmium(II). 19,20,21,22 These metal complexes confer attractive redox and photophysical properties on the polymer and different metal loadings can be prepared by simply varying the relative mole ratio of the reactants.…”

Organometallic Ferrocene- and Phosphorus-Containing Polymers: Synthesis and Characterization

“…Until recently, synthetic difficulties associated with the creation of macromolecular chains possessing metal atoms as a key structural component have held back progress in the field. Over the past decade or so, these synthetic obstacles have been, in part, overcome through many creative procedures to prepare new materials [1,[20][21][22][23][24][25][26][27]. The new approaches that are now available have led to macromolecular structures in which metals are not only incorporated via the use of traditional covalent bonds but also by potentially reversible coordination interactions of comparable importance to these synthetic developments, these new materials have shown that they can possess a diverse range of interesting and useful properties and potential applications that complement those of organic macromolecules [1,[20][21][22][23][24][25][26][27].…”

Unique Metal‐Diyne, ‐Enyne, and ‐Enediyne Complexes: Part of the Remarkably Diverse World of Metal‐Alkyne Chemistry

“…Reaction of MgBr 2 with alkynyl-Li salts is also an effective route to such Grignard reagents (29). More recently, calcium, strontium, and barium triphenylsilylethynyl derivatives of the form [M( [18]crown-6)(C À À À À À À CSiPh 3 ) 2 ] (M ¼ Ca, Sr, Ba) have been prepared via treatment of alkaline earth amides [M(N(SiMe 3 ) 2 ) 2 (thf) 2 ] (M ¼ Ca, Sr, Ba; thf ¼ tetrahydrofuran, ligand), with Ph 3 SiC À À À À À À CH in the presence of [18]crown-6 in THF (advent) (35).…”
