Synthesis and property studies of linear and kinked poly(pyreneethynylene)s

A series of fluorescent conjugated polymers, poly(pyreneethynylene)s, have been designed and synthesized to investigate the effect of shape of polymer backbone on physical properties. Polymers with linear and kinked backbone were synthesized using 1,6- and 1,8-disubstituted pyrene. The target copolymers were designed to incorporate various spacer units, such as, alkoxyphenyl, carbazole and fluorene on the polymer backbone. Characterization of the target compounds was achieved by NMR, IR, GPC and MALDI-TOF mass spectrometry. Detailed investigation on their optical, electrochemical and thermal properties revealed significant contribution of the geometry of polymer backbone towards physical properties. Kinked backbone of cisoid-polymers was found to result in lower optical band gap, less negative EHOMO and higher thermal stability as compared to their linear analogues, most probably due to the coiling of polymer chains. Comparison of the physical properties of the polymers with those of the model compounds suggested similar extent of conjugation through 1,6- and 1,8-position of pyrene.

Tuning the intramolecular charge transfer of alkynylpyrenes: Effect on photophysical properties and its application in design of OFF-ON fluorescent thiol probes

(Figure Presented) Green and yellow-emitting 1,6- and 1,8- bis(phenylethynyl) pyrenes (dyes 7, 8, 9, and 10) with different intramolecular charge transfer (ICT) feature were synthesized and the effect of ICT on the photophysical properties of these deriva

Supramolecular helix of an amphiphilic pyrene derivative induced by chiral tryptophan through electrostatic interactions

An amphophilic pyrene derivative (PyDNH3) bearing positively charged ammonium cations has been synthesized and characterized. Self-assembly of PyDNH3 in the presence of chiral tryptophan derivatives was investigated in ethanol/water by optical and chiroptical spectra, indicating the formation of helical aggregates. Scanning electron microscope (SEM) images showed the formation of ring-shape structures.

Synthesis and photophysical properties of a highly fluorescent ditopic ligand based on 1,6-bis(ethynyl)pyrene as central aromatic core

A simple synthetic route for the efficient preparation and purification of two regioisomers of a pyrene derivative containing two ethynyl groups - 1,6- and 1,8-bis(ethynyl)pyrene - is described. The former compound was used as a building block for the ste

Synthesis and Molecular Recognition of Pyrenophanes with Polycationic or Amphiphilic Functionalities: Artificial Plate-Shaped Cavitant Incorporating Arenes and Nucleotides in Water

Water-soluble pyrenophanes possessing polycationic or amphiphilic side chains have been developed as synthetic host molecules to investigate hydrophobic and/or π-stacking interactions. By utilizing ω-acetalic alkyl side chains to retain solubility and ver

SYNTHESIS OF PYRENE DERIVATIVES

The direct iodination of pyrene with the I2-HIO3-H2SO4 system gives a mixture of 1,6- and 1,8-diiodopyrenes with a preponderance of 1,6-diiodopyrene.Increase in the reaction temperature to 100 deg C leads to an increase in the yield of the second isomer.I

Chemical process

There is disclosed a process for the direct iodination of polyarylidene compounds to provide highly pure para-substituted diiodo derivatives. The polyarylidene compound is reacted with iodine in the presence of an oxidant, unreactive with the aromatic nucleus, in a reaction medium containing a solvent for the polyarylidene compound, a catalyst and water. The reaction medium is recovered for reuse in subsequent reactions by the removal of spent oxidant which, in the preferred embodiment, is based upon the temperature dependent differences in solubility between the diiodo derivative and the spent oxidant.
