Strong solid-state greenish-blue emitting, mono-cyclometalated iridium complexes, [Ir(ppy)(PPh(3))(2)(H)(Cl)], 2a and [Ir(F(2)ppy)(PPh(3))(2)(H)(Cl)], 2b [ppyH = 2-phenylpyridine; F(2)ppyH = 2-(2',4'-difluoro)phenylpyridine], have been synthesized by a convenient route. The 'aggregation induced enhanced phosphorescence (AIEP)' activity exhibited by these complexes has been rationalized.

We have synthesized polyacrylamide-polypyrrole (PPy/PA) microparticles which present conductivity in the range of the semiconductor materials (around 10 S/cm). Glucose Oxidase was immobilized within microparticles with composition 50/50 (w/w) PPy/PA. These microparticles were used as biological component of an amperometric biosensor which shows similar glucose response in both aerobic and anaer...

Polypyrrole nanoparticles (PPy NPs) exhibit strong absorption in the near infrared (NIR) region. With an excellent photothermal efficiency of ~45% at 808 nm, sub-100 nm PPy NPs are demonstrated to be a promising photothermal agent for in vivo cancer therapy using NIR irradiation.

OBJECTIVE To compare exercise tolerance testing (ETT) with gated single photon emission computed tomography-myocardial perfusion imaging (SPECT-MPI) risk stratification in women with an intermediate to high CAD pretest risk and known estrogen status (ES). BACKGROUND SPECT-MPI is an effective test for risk stratifying patients with stable angina. However in women, the current guidelines recomm...

An antibacterial and conductive bionanocomposite (BNC) film consisting of polypyrrole (Ppy), zinc oxide (ZnO) nanoparticles (NPs), and chitosan (CS) was electrochemically synthesized on indium tin oxide (ITO) glass substrate by electrooxidation of 0.1 M pyrrole in aqueous solution containing appropriate amounts of ZnO NPs uniformly dispersed in CS. This method enables the room temperature elect...

In this study, a simple one-step preparation of polypyrrole (PPy) assisted by an organic dye, acriflavine hydrochloride (AF), was investigated. The presence dye resulted in the development PPy nanofibers with conductivity enhanced up to 14 S cm–1. structural analysis Fourier-transform infrared and Raman spectroscopies confirmed interaction AF PPy. As far as electrochemical activity is concerned...

This paper presents the design and fabrication of proximity coupled feed disk resonator coated with Multi Walled Carbon Nanotubes (MWCNTs) and Polypyrrole-Chitosan (PPy-CHI) layers as a napropamide sensor. Computer Simulation Technology (CST) microwave studio was used to obtain the best design of disk resonator and feed line position in 5 GHz resonant frequency. Also, MWCNTs - PPy-CHI layers we...

Because of the widespread use wireless communication and electronic devices, electromagnetic radiation has become a global environmental pollutant. Therefore, finding excellent microwave absorbers (MAs) with appropriate magnetic loss dielectric matching is an urgent assignment. In this work, we successfully fabricated 3D architectures cabbage-like CoFe2O4 (CFO) cauliflower-like polypyrrole (PPy...

A series of triscyclometalated iridium complexes with oligofluorene-substituted ppy ligands manifest impressive two- and three-photon absorption properties. In particular, a star-shaped complex bearing three carbazole-terminated trifluorenyl ppy demonstrates a large three-photon absorption cross section up to 81 × 10(-78) cm(6) s(2) photon(-2). In combination with optimal phosphorescence quantu...
