- 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?).

- Eumelanin-inspired core derived from vanillin: A new building block for organic semiconductors
-
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.

- Molecular spoked wheels: Synthesis and self-assembly studies on rigid nanoscale 2D objects
-
We present the efficient synthesis of a new molecular spoked-wheel structure (MSW-3). Two derivatives with diameters of approximately 4 nm have been prepared. By highlighting the importance of pseudo-high-dilution conditions during cyclization, we were able to access the compounds on a several hundred milligram scale. In addition to the standard characterization (NMR spectroscopy, MS), we describe a detailed investigation of the optical properties of the fluorescent MSWs by comparison with appropriate model chromophores. Furthermore, a comprehensive study of the structure in solution by means of light- and X-ray scattering experiments has been conducted. Scanning tunneling microscopy (STM) revealed the two-dimensional organization of the molecules on highly oriented pyrolytic graphite and emphasized the spoked-wheel structure. The diameter of these molecules measured by small-angle X-ray scattering is in very good agreement with that obtained from STM and matches the results of molecular modeling. This confirms the rigidifying effect of the spokes, which results in highly shape-persistent nanometer-sized oblate organic compounds. Copyright

- New soluble rigid rod copolymers comprising alternating 2-amino-pyrimidine and phenylene repeat units: Syntheses, characterization, optical and electrochemical properties
-
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.
