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?).

An eumelanin-inspired core derived from the natural product, vanillin (vanilla bean extract) was utilized for the synthesis of eumelanin-inspired small molecules and polymer via Sonogashira cross coupling. The materials demonstrate that the methyl 4,7-dibromo-5,6-dimethoxy-N-methyl-1H-indole-2-carboxylate core can serve as a new building block for organic semiconductors.

Oligo(p-phenylene ethynylene)-BODIPY derivatives: Synthesis, energy transfer, and quantum-chemical calculations

The synthesis and energy-transfer properties of a series of oligo(p-phenylene ethynylene)-BODIPY (OPEB) cassettes are reported. A series of oligo(p-phenylene ethynylene)s (OPEs) with different conjugated chain lengths as energy donor subunit in the energy-transfer system were capped at both ends with BODIPY chromophores as energy-acceptor subunits. The effect of the conjugated chain of OPEs on energy transfer in the OPEB cassettes was investigated by UV/Vis and fluorescence spectroscopy and modeling. With increasing number n of phenyl acetylene units (n=1-7), the absorption and emission maxima of OPEn are bathochromically shifted. In the OPEBn analogues, the absorption maximum assigned to the BODIPY moieties is independent of the length of the OPE spacer. However, the relative absorption intensity of the BODIPY band decreases when the number of phenyl acetylene units is increased. The emission spectra of OPEBn are dominated by a band peaking at 613 nm, corresponding to emission of the BODIPY moieties, regardless of whether excitation is at 420 or 550 nm. Furthermore, a very small band is observed with a maximum between 450 and 500 nm, and its intensity relative to that of the BODIPY emission increases with increasing n, that is, the excited state of OPE subunits is efficiently quenched in OPEBn by energy transfer to the BODIPY moieties. Energy transfer (ET) from OPEn to BODIPY in OPEBn is very efficient (all φET values are greater than 98 %) and only slightly decreases with increasing length of the OPE units. These results are supported by theoretical studies that show very high energy transfer efficiency (φET>75 %) from the OPE spacer to the BODIPY end-groups for chains with up to 15-20 units.

A new type - π-conjugated copolymers of 2-amino-pyrimidine was prepared between 2-amino-4,6-diiodidepyrimidine and 1,4-dibromo-2,5-dialkoxybenzene by Sonogashira polycondensation. The structures of the copolymers were elucidated by FT-IR, 1H NMR and 13C NMR, fluorescence spectroscopy, gel permeation chromatography, thermal analysis and element analysis. The derived polymers were soluble in common organic solvents and trifloroacetic acid and exhibited good thermal stability. They emitted green light under UV irradiation in solid state and blue or green light in solution phase, respectively. Electrochemical behavior of these new polymers depicted facile p-doping and good electron-transporting properties. These polymers displayed bathochromic shift when protonated with CH3SO3H acid in chloroform solutions or m-cresol solutions and the red-shifted peaks were observed from 490 nm to 652 nm. XRD patterns of copolymers showed that the intensity of peaks was enhanced with increasing alkyloxy chain length.

body text, p. 2226 - 2232 (2011/09/16)
The click-ligands based on 1,2,3-triazole and pyridine unit has been synthesized via Cu(I)-catalyzed alkyne-azide cycloaddition from corresponding organic azides and terminal alkynes. The ligand structure was characterized by NMR, IR and elemental analysis as well as single crystal diffractions. The single crystal structure of the complexes from two different ligands coordinating to Cu(II) and Co(II) ions indicated that the N(2) atom in 1,2,3-triazole unit can act as an efficient donor to metals through the rational molecular design.
