“…There is widespread interest in the properties and potential applications of liquid crystalline conjugated polymers [1][2][3][4][5][6][7][8][9][10][11][12] , and pyrrole is one of the most promising building-blocks for the backbones of such polymers. However, the frequently-used 3-substituted pyrroles are nonsymmetrical monomers, effectively having a head (H) and a tail (T) 1 .…”

The synthesis and characterisation of a pyrrole monomer substituted at the Nposition with a liquid crystal group are reported. Polymerisation of this compound produced an infusible, soluble liquid crystalline semiconducting polymer. The sidechain of the polymer had a flexible spacer of nine methylene units, terminated by a mesogenic cyanobiphenyl group. All the new compounds were chemically characterised and some were found by hot-stage polarised optical microscopy to exhibit liquid crystal mesophases. The polymer was lightly doped p-type by iodine vapour, and its electrical conductivity was measured.

“…Antitubercular, 5,6 anti-tumour, 7 anti-inflammatory, 8 HIV fusion inhibitory 9 and cholesterol-lowering 10 activities are amongst the biological activities demonstrated by several pyrrole derivatives. Furthermore, pyrrole has been used as a building block for the synthesis of new materials for the development of solar cells, 11 chiral liquid crystals 12 and supramolecular 13,14 assemblies.…”

A new class of diaryl-pyrrole derivatives of the polyaromatic hydrocarbons (PAH) benzene, naphthalene, anthracene and pyrene were synthesized in a multicomponent reaction under microwave irradiation and studied in solution at room (293 K) and low (77 K) temperature. The study includes a complete spectroscopic evaluation (singlet-singlet and triplet-triplet absorption, fluorescence and phosphorescence spectra) as well as photophysical evaluation (fluorescence, phosphorescence and triplet lifetimes together with fluorescence and triplet occupation and singlet oxygen sensitization quantum yields). From the above evaluation, a complete set of deactivation rate constants (kF, kIC and kISC) could be obtained. The study was further complemented with TDDFT calculations. It is shown that, with the exception of the anthracene derivative, the diaryl-pyrrole moiety strongly influences the spectral and photophysical properties of the PAH and that with the exception of the benzene derivative, the excited state internal conversion deactivation channel of the diaryl-pyrrole derivatives is higher than that of the PAH counterparts.

“…To improve electrochemical and/or thermal behavior of pyrrole‐derived polymers, for instance, pyrrole‐based liquid crystals6–8 and 3‐cyanopropyl pyrrole, pentafluorophenyl 1‐ H ‐pyrrole,9 1‐substituted crown pyrroles,10 and 1‐alkyl pyrroles11 were synthesized and polymerized. Attempts to electrochemically polymerize 1‐hydroxyalkyl pyrroles and tosylated 1‐hydroxyalkyl pyrroles were not successful because of the steric hindrance when the alkyl chain has 2 or 3 carbon atoms 12–14…”

1-Substituted pyrroles such as 1-(hydroxymethyl)pyrrole, 1-(3-hydroxypropyl) pyrrole, 1-H-1-pyrrolylmethyl 4-methyl-1-benzenesulfonate, 1-H-1-pyrrolylpropyl 4-methyl-1-benzenesulfonate, and 1-H-pyrrolylmethyloctanoate were synthesized and oxidative polymerized and copolymerized with pyrrole by using (NH 4 ) 2 Ce(NO 3 ) 6 and FeCl 3 . Some of the copolymers were slightly soluble in DMF and DMSO. The products were characterized by FTIR, 1 H-NMR, and four-point probe conductivity.
