Modification by Fluorine as Efficient Tool for the Enhancement of the Performance of Organic Electroactive Compounds – A Review

Functionalization of organic semiconductors with fluorine atoms and fluorine-containing groups can give rise to a wide variety of properties, for example, increase the rate of electron transport, induce harvesting of non-emissive triplet excitons through thermally activated delayed fluorescence (TADF) or room temperature phosphorescence (RTP), improve photoluminescence quantum yield (PLQY) by forming multiple intra- and intermolecular interactions, and increase solution- processabitily of the compounds, therefore, lowering the cost of device fabrication.

Synthesis, Characterization and Photophysical Study of 4,4’-Diamino-2,2’-stilbenedisulfonate with Lanthanide Ions Complexes

Complex of 4,4’-diamino-2,2’-stilbenedisulfonic acid (DSD) with trivalent lanthanide ions Eu3+ and Tb3+ were prepared at the ratio of 3:1 (DSD:Ln). The complexes with ions present in the form of powder show black (Eu3+) and brown (Tb3+) colors.

Structural Organization of Polymer Metal Complexes with Water or Phenanthroline and their Influence on Luminescence Properties

A monomer – 2-methyl-5-phenylpentene-1-dione-3,5, its solvent metal complex  Eu(III)-water, hybrid metal complex Eu(III)-phenanthroline, new metallopolymers based on them are obtained. The results of above studies have shown that the configuration of the chelate unit is unchanged during polymerization. Using the electron microscopy the homogeneity of metal distribution in the polymer matrix of synthesized metallopolymer was confirmed.
