Fluorene‐containing tetraphenylethylene molecules as lasing materials
A series of star-shaped oligofluorene molecules, each containing a TPE core, have been specifically designed and produced to show effective aggregation-induced emission (AIE). Each molecule differs either in the number of fluorene units within the arms (e.g., 1 or 4, compounds 4 and 5), or the terminal group positioned at the end of each arm (e.g., H, TMS, or TPA, compounds 4, 6, and 7). Althou...
متن کاملAromatic-ring-layered polymers composed of fluorene and xanthene
INTRODUCTION Conjugated polymers show intriguing properties such as electrical conductivity,1–4 electroluminescence5–9 and chemical-sensing ability.10–12 Synthesis of new conjugated polymers is an important subject in polymer chemistry as well as in material chemistry, owing to their potential applications in optoelectronic devices. Generally, p-electrons are delocalized throughout the conjugat...
متن کاملIsolation and characterization of a fluorene-degrading bacterium: identification of ring oxidation and ring fission products.
An Arthrobacter sp. strain, F101, able to use fluorene as the sole source of carbon and energy, was isolated from sludge from an oil refinery wastewater treatment plant. During growth in the presence of fluorene, four major metabolites were detected and isolated by thin-layer chromatography and high-performance liquid chromatography. 9-Fluorenol, 9H-fluoren-9-one, and 3,4-dihydrocoumarin were i...
متن کاملTransmittance of MIM Waveguides Containing Semi-Circular Ring Shaped and Rectangular Ring Shaped Grooves
In this paper the transmittance of metal-insulator-metal (MIM) waveguides containing semi-circular ring shaped and rectangular ring shaped grooves are investigated. By varying groove parameters their effects on the transmittance of the MIM waveguides are investigated. The results show that the transmittance spectra of the waveguides have maximum and minimum points, and by using appropriate para...
متن کاملDyeing Properties of Some New Disperse Dyes Containing Piperazine Moiety
Four novel azo disperse dyes based on 1-4-bromobenzyl-4-phenylpiperazine were synthesized in two steps, using alkylation and azo coupling reactions. Chemical structure of the dyes was characterized and confirmed by the Ultraviolet Visible UV-Visible, Fourrier Transform Infrared FT-IR, Proton Nuclear Magnetic Resonance 1H NMR and Carbon Nuclear Magnetic Resonance 13C NMR analyses. The solvatochr...
