We investigate the interaction between conjugated polyelectrolytes and surfactants in solution and solid phases. We identify multiple modes of interaction and propose a model that accounts for their interplay and pronounced variation in photophysics over a wide range of conditions.

A P-C bond-forming reaction has been applied to the convenient preparation of tetraarylphosphonium polyelectrolytes (TPELs) from aryl dihalides and diphenylphosphine. A TPEL having a thermal decomposition temperature of 460 °C that is also stable to heating at 65 °C in 6 M NaOH(aq) for at least 24 h has been prepared by this method.

Three-dimensional conjugated poly(azomethine) networks were found to be promising candidates for applications in photocatalytic water splitting. Straightforward synthetic protocols lead to fully organic photocatalysts that showed enhanced long-time stability. Furthermore, the catalytic performance of these materials was correlated to the molecular composition and the optoelectronic properties o...

Chemical oxidation of poly(enetetramine)s was demonstrated as a new synthetic route to prepare conjugated polyelectrolytes.

Bactericidal efficacy of gold nanoparticles conjugated with ampicillin, streptomycin and kanamycin were evaluated. Gold nanoparticles (Gnps) were conjugated with the antibiotics during the synthesis of nanoparticles utilizing the combined reducing property of antibiotics and sodium borohydride. The conjugation of nanoparticles was confirmed by dynamic light scattering (DLS) and electron microsc...

We herein find that graphene oxide (GO) can enhance the fluorescence signal of conjugated polyelectrolytes (CPEs) with charge transfer characteristics under certain conditions, which is due to a relative hydrophobic environment of CPEs upon complexation with GO.

background: considering the effect of preterm delivery in morbidity and mortality of newborns, its precaution and prevention is so important. objective: to investigate the association between second trimester maternal serum biomarkers (human chorionic gonadotropin, alpha-fetoprotein, non-conjugated estrogen, inhibin a) and pre-term delivery. materials and methods: this is a historical cohort st...

An enzyme-linked immunosorbent assay for neopterin using penicillinase as marker enzyme is reported here by polyclonal antibodies against neopterin conjugated to bovine serum albumin which were raised in rabbits. Immunoglobulin fractions were purified and coated on wells of microtiter plates. A chain heterology was introduced in neopterin derivative and conjugated to penicillinase. The assa...
