Polymers 103-111 epoxide hydrolase 1 Homo sapiens 35-38 15884078-2 2005 We demonstrate this with the example of one of the most commonly studied polymers, poly(2-methoxy-5-(2"-ethylhexoxy)-1,4-phenylenevinylene), MEH-PPV, which is shown to exhibit sharp fluorescence signatures over one hundred times narrower than the ensemble. Polymers 73-81 epoxide hydrolase 1 Homo sapiens 141-144 15053595-4 2004 The fluorescence (photoluminescence) of isolated MEH-PPV conjugated polymer molecules imbedded in the device was observed to exhibit diverse time- and electrical bias-dependent effects. Polymers 68-75 epoxide hydrolase 1 Homo sapiens 49-52 16095381-1 2005 We study electrochemical p- and n-type doping in the well-known light-emitting polymer poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV). Polymers 79-86 epoxide hydrolase 1 Homo sapiens 146-149 15169428-1 2004 We determine the efficiencies for the formation of excitons and charge carriers following ultrafast photoexcitation of a semiconducting polymer (MEH-PPV). Polymers 136-143 epoxide hydrolase 1 Homo sapiens 145-148 10958774-0 2000 Unmasking electronic energy transfer of conjugated polymers by suppression of O(2) quenching The photochemistry of poly[2-methoxy, 5-(2"-ethyl-hexyloxy)-p-phenylene-vinylene] (MEH-PPV) has been found to be highly dependent on the presence of O(2), which increases singlet exciton quenching dramatically. Polymers 51-59 epoxide hydrolase 1 Homo sapiens 176-179 10958774-1 2000 Spectroscopy on isolated single molecules of MEH-PPV in polycarbonate films that exclude O(2) reveals two distinct polymer conformations with fluorescence maxima near 555 and 580 nanometers wavelength, respectively. Polymers 115-122 epoxide hydrolase 1 Homo sapiens 45-48 34610057-3 2021 This article presents a detailed investigation on the influence of defective electronic states of MgO nanoparticles on the photophysical properties and photostability of a conjugated polymer, poly(2-methoxy-5-(2-ethylhyxyloxy)-1,4-phenylene vinylene) (MEH-PPV). Polymers 183-190 epoxide hydrolase 1 Homo sapiens 252-255 35506539-4 2022 All of the polymers when highly diluted (c = 0.1 wt %) exhibited massive eta increases after stretching to very large strains (~300-500%) via micronecking, with the rigid polyfluorene (PFO) and semirigid MEH-PPV both manifesting eta 90%, while the most flexible yet regioregular polythiophene (P3HT-rr) exhibited a 10-fold increase to ~21%.
