Fluorescence of protonated pyrene and coronene in neon matrices
Please cite this article in press as: I. Garkusha e Fluorescence spectra of protonated pyrene and coronene in solid neon have been observed. Laser excitation of the Sn S0 transitions of the cations results in an extended, vibrationally-resolved S1 ? S0 fluorescence with onset at 487.8 and 695.4 nm for protonated pyrene and coronene, respectively. Vibrational assignment of the spectra has been m...
متن کاملPatterns of ring current in coronene isomers.
The ipsocentric pseudo-p model is used to predict maps of induced current density for isomeric variations of coronene in which the central hexagonal ring is surrounded by 5, 6, and 7-membered rings. All isomers in the set are predicted to support strong diatropic perimeter ring currents, thereby conforming to the magnetic criterion of aromaticity.
متن کاملDescribing curved-planar π-π interactions: modeled by corannulene, pyrene and coronene.
The specific π-π interactions between curved and planar structures, which are different from the general π-π interactions between planar arenes, have generated great attention due to their brand-new, unique, and fascinating photoelectric properties. Herein, the curved-planar (C-P) π-π interactions between corannulene, pyrene and coronene have been investigated using the DFT-D method. A series o...
متن کاملSpin Filtering in Zigzag Graphene Nanoribbons Using 7-5 Defects
Electrons carry both charge and spin. The processing of information in conventional electronic devices is based only on the electronic charge. Spin electronics, or spintronics, uses the spin of electrons as another degree of freedom [1]. Materials with zero band gap form the basis for spintronic devices and show superior performance in comparison with non-zero band gap materials [1]. Graphene, ...
متن کامل1-[(5-Bromopentyloxy)methyl]pyrene
In the title compound, C(22)H(21)BrO, other than the Br atom, the non-H atoms are approximately co-planar [maxium deviation = 0.178 (2) Å] and the alk-oxy chain shows an all-anti conformation. A weak inter-molecular C-H⋯Br hydrogen bond contributes to the stabilization of the crystal structure.
