In this study, we used click chemistry to synthesize new linear polypeptide-g-pyrene polymers from a mono-azido-functionalized pyrene derivative (N3-Py) and several poly(γ-propargyl-l-glutamate) (PPLG) oligomers. Incorporating the pyrene units as side chains enhanced the α-helical conformations of these PPLG oligomers in the solid state, as determined using Fourier transform infrared (FTIR) spectroscopy; it also increased the temperature stability of the α-helical secondary structures of the grafted PPLG oligomers, relative to those of the pure PPLG species, as revealed through temperature-dependent FTIR spectroscopic analyses. In addition, the thermal properties of the PPLG-g-Py polypeptides (e.g., glass transition temperatures increased by ca. 100 °C) were superior to those of pure PPLG oligomers. Mixing the PPLG-g-Py oligomers with multiwalled carbon nanotubes (MWCNTs) in dimethylformamide led to the formation of highly dispersible PPLG-g-Py/MWCNT organic/inorganic hybrid complex materials. Fluorescence emission spectra revealed significant π-π stacking between the PPLG-g-Py oligomers and the MWCNTs in these complexes. 2013 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

Synthesis, photophysical and electrochemical properties and DSSC application of triphenylaminochalcone cored dendrimers with anthracene and pyrene as surface groups and triazolylcholanoate as the bridging unit

, p. 16542 - 16554 (2018)
Triphenylaminochalcone-cored dendrimers decorated with anthracene and pyrene at the periphery have been synthesized by a convergent methodology using a click chemistry approach and characterized from spectral data and elemental analyses. All the dendrimers show excellent optical and electrochemical properties. Higher generation dendrimers exhibit better power conversion efficiency than lower-generation dendrimers when used as additives in dye-sensitized solar cells (DSSCs).

A click-reaction was site-selectively carried out on 1000 and 12000 microelectrode arrays and characterized using TOF-SIMS.
Evaluation of readily accessible azoles as mimics of the aromatic ring of D-phenylalanine in the turn region of gramicidin S
