“…A wide range of suitable monomers has been copolymerized comprising (hetero)polyaromatic compounds [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33], and more sophisticated functionalities like conjugated oligomers [34][35][36][37][38][39], triphenylmethane [40][41][42][43][44][45][46][47], azo [48][49][50][51][52], or polymethine [53][54][55][56][57] dyes. Even transition metal coordination compounds of aluminum [58,59], iron [60], zinc [61][62][63], ruthenium [64, 65], europium …”

“…It should be noted that using dye-functionalized vinylether terminating agents results in quantitatively dye-labeled polymer chains; using acrylate-functionalized terminating reagents results in formation of a significant amount of methylene terminated polymer chains as side product [74]. Aldehydes react with Schrock-type (molybdenum carbene) initiators as well as tungsten or titanium-based initiators in a Wittig-type reaction and can be used as terminating reagents for these systems [35,73,75].…”

Herein, highlights from the recent literature regarding functional dye-polymer conjugates obtained by ring opening metathesis polymerization (ROMP) are presented and the different approaches to incorporate dyes during the initiation, propagation, and termination step in ROMP are discussed. Applications in the field of chemical sensors, bioimaging, electroactive materials, self-assembly, photochromic and photoreactive materials are used to illustrate the versatility of ROMP as a technique to prepare complex functional materials.

“…Furthermore, any type of functionalizable dye or charge transport material may be used as a side chain, allowing a great range of emission wavelengths and charge transport properties [209]. Examples of this strategy involve side-chain polymers such as poly(norbornene)s [210], poly(methacrylate)s [209,211,212], poly(styrene)s [208, 213 -215], poly(siloxane)s [216] poly(methyltetracyclododecene) [217] or polyethers [218] with different pendant chromophores.…”

Electroluminescence has been a subject of interest for several decades because of its many applications in areas such as telecommunications or information displays. Light‐emitting diodes using p‐n junctions of inorganic semiconductors have dominated the field in the last twenty years; however, efficient blue emission has only recently been achieved and inorganic semiconductors are difficult to form over large areas, making the process uneconomic. During the last decade, an explosive growth of activity in the area of organic electroluminescence has occurred in both academia and industry, stimulated by the promise of light‐emitting plastics for the fabrication of large, flexible, inexpensive and efficient screens to be used in different applications. Thus, a substantial amount of research is presently directed towards color control and improvement of manufacturability and reliability of devices in order to make their commercialization viable. A great deal of work has been carried out by physicists and materials scientists concerned with the preparation of different device structures and with the use of different techniques for device manufacture. However, all this work would not be possible without the continuous efforts of synthetic chemists to prepare materials with enhanced luminescent properties and processabilities. This article provides a review of the main types of organic materials that have been used in the fabrica‐tion of light‐emitting diodes either as emitting materials or as charge‐transport layers. Special attention will be paid to the different synthetic strategies that have been followed in order to tune the color of the emission, to increase stability of materials and to enhance their processabilities.

“…Novel light emitting electro-and photoluminescent polynorbornenes have been synthesized by ROMP and RPP of norbornenes containing phenylenevinylene oligomer 8 and fluorescein 9 units in the side chain. One easy way to produce coumarine-containing polymers is to synthesize a coumarine-containing monomer followed by its ROMP.…”
