Synthesis of oligoferrocenylenearylenes and the X-ray structure of 1,4-bis(tricarbonylmethyltungstentetramethylcyclopentadienyl)benzene
Southard, Glen E.,Curtis, M. David
, p. 1177 - 1184 (2002)
Soluble oligo-(1,1′-ferrocenylene-2,5-dihexylphenylene) and oligo-(1,1′-ferrocenylene-2,5-didodecyloxylphenylene) were prepared by the Suzuki coupling of the ferrocene diboronic acid and the 1,4-phenylene diiodide. Direct reaction of lithium 1,4-bis(tetramethylcyclopentadienide)benzene or lithium 2,5-bis(tetramethylcyclopentadienide)thiophene with Fe(II) halides afforded insoluble ferrocenylenearylene oligomers, and with W(CO)6 followed by MeI gave a model dimer whose crystal structure was determined. The magnetic properties of the ferrocene oligomers exhibit anomalous behavior that is explained in terms of the properties of the individual ferrocene groups, rather than to cooperative behavior.

A family of rigid rod like 2,5-dodecanoxy-phenyleneethynylene oligomers having 3, 5, 7, and 9 repeating units was selectively synthesized by a bi-directional iterative divergent-convergent approach. Starting from a central 1,4-bis(dodecanoxy)-2,5-diiodobe
Benzylidenecyclohexanone-triazole-based conjugated polymer: Click synthesis, Staudinger end-capping and application as optical probe scaffold

A type of benzylidenecyclohexanone-triazole based conjugated polymer (P5) was successfully synthesized by Cu+-catalyzed Click reaction. The THF solution of P5 exhibited specific optical response (increase in absorption and decrease in fluorescence) toward I?. With the further addition of Hg2+ into the assembly of P5-I?, distinctive recovery of optical properties was detected, suggests that P5-I? adduct can act as fluorescence turn-on probing platform for Hg2+. Post-polymerization of P5 was implemented by catalyst-free Staudinger reaction between P5 and triphenylphosphine to afford phosphinimine-endcapped polymer (P5-TPP). Different from the blue-greenish emission (~490?nm) of P5, P5-TPP emitted yellow light (~550?nm) in THF–water mixture (VTHF/Vwater?=?2/8). P5-TPP displayed specific fluorescence ratiometric alteration toward hypochlorite ion in THF–water mixture (VTHF/Vwater?=?2/8, pH?=?7.4), which might be due to the hypochlorite-induced hydrolysis of phosphinimine energy-transfer acceptors in P5-TPP. The results suggest that P5 can act as structure scaffold for the construction of optical probe for triple analytes (I?, Hg2+ and ClO?).

Functional phenylethynylene side arm poly(arylene ethynylene) conjugated polymers: Optical and electrochemical behavior for enrichment of electronic applications
Arun Kumar,Gomathi Priya,Alagar
, p. 5767 - 5773 (2018)
The poly(arylene ethynylene) (PAE) conjugated polymers (CPs) with a donor-acceptor (D-A) side arm have been designed and synthesized using Sonogashira cross coupling in the presence of cyano methylene, or cyano thiophene gave diethynyl (A) and alkoxy and alkyl substituted diiodo aryl monomers (D). An interesting electronic response in optical measurements such as UV-visible (UV-vis) and fluorescence (FL) spectra was observed in tetrahydrofuran solvent. From the FL spectra, it was observed that the CP solutions possess an interesting long bathochromic shift when compared with the UV-vis spectra, because of the electron withdrawing, electron releasing and conjugation effects. The electrochemical and thin film UV-vis spectral measurements provided highest occupied molecular orbital-lowest unoccupied molecular orbital (HOMO-LUMO) electronic energy levels and their corresponding semiconducting electronic energy gaps (Eg) of the PAE CPs. Among the side arm CPs, polymers P1 and P5 have low Eg of 2.14 eV and 2.17 eV. The new PAE CPs are reliable for use in electronic and photonics applications.

A novel αchromophoric 1,4-bis(anthracenylethynyl)benzene (BAB)-based highly emissive J-aggregated organogel has been synthesized and characterized. Single-crystal structure determination of asymmetric π-chromophoric bola-amphiphilic BAB1 (dodecyl and triethyleneglycolmonomethylether containing side chains of bis(anthracenylethynyl)benzene) supports J-aggregation. Further, a photochromic acceptor chromophore, 4,4′-(perfluorocyclopent-1-ene-1,2-diyl)bis(5-methylthiophene-2-carbaldehyde), is noncovalently encapsulated in the gel and photoswitching studies have been performed based on photochromic F?rster resonance energy transfer. The modulated emission of the processable soft material is further exploited for rewritable display. However, BAB2 (dodecyl side chain on both sides) does not show gelation property due to its low solubility.

A solvent responsive dynamic nanoscale metal-organic framework (NMOF) [Zn(1 a)(H2O)2] has been devised based on the self-assembly of ZnII and asymmetric bola-amphiphilic oligo-(p-phenyleneethynylene) (OPE) dicarboxylate linker 1 a having dodecyl and triethyleneglycolmonomethylether (TEG, polar) side chains. In THF solvent, NMOF showed nanovesicular morphology (NMOF-1) with surface decorated dodecyl chains. In water and methanol, NMOF exhibited inverse-nanovesicle (NMOF-2) and nanoscroll (NMOF-3) morphology, respectively, with surface projected TEG chains. The pre-formed NMOFs also unveiled reversible solvent responsive transformation of different morphologies. The flexible NMOF showed cyan emission and no cytotoxicity, allowing live cell imaging. Cisplatin (14.4 wt %) and doxorubicin (4.1 wt %) were encapsulated in NMOF-1 by non-covalent interactions and, in vitro and in vivo drug release was studied. The drug loaded NMOFs exhibited micromolar cytotoxicity.
Pure white light emission and charge transfer in organogels of symmetrical and unsymmetrical π-chromophoric oligo-: P -(phenyleneethynylene) bola-amphiphiles
Roy, Syamantak,Samanta, Debabrata,Kumar, Pramod,Maji, Tapas Kumar
supporting information, p. 275 - 278 (2018/01/12)
Two novel bola-amphiphilic oligo-p-(phenyleneethynylene) (OPE) dicarboxylates have been synthesized having non-polar and mixed-polar side chains. This led to gelation in both with vesicular morphology. Upon in situ loading of a suitable dye and redox-active molecule, pure white light emitting and charge transfer (CT)-gels, respectively, were realized.
