Using 7-hydroxy-1-indanone as a prototype (I), which exhibits excited-state intramolecular proton transfer (ESIPT), chemical modification has been performed at C(2)-C(3) positions by fusing benzene (molecule II) and naphthalene rings, (molecule III). I undergoes an ultrafast rate of ESIPT, resulting in a unique tautomer emission (λ(max) ∼530 nm), whereas… (More)
OBJECTIVE Since virus infections in AIDS patients are mostly inevitable and as they frequently cause disease deterioration and therapeutic failures, a comprehensive investigation was made of the influence of the coinfections of 9 well-known viruses on disease progression in patients infected with human immunodeficiency virus type 1 (HIV). METHODS A… (More)
The title compound, C(17)H(12)N(2), comprises a norbornane unit having a dicyanona-phthalene ring fused on one side. Both cyano groups are twisted slightly out of the plane of the naphthalene ring system [C-C-C-C torsion angle = 1.9 (2)°]. In the crystal, inversion-related mol-ecules are linked by pairs of weak C-H⋯N hydrogen bonds, forming dimers.
The URA is one of the coded aperture imaging techniques. It has been used or proposed for X-ray imaging. In the URA, the pinhole is replaced by multi-pinholes array arranged in m-sequences. The pattern of the array is set as its correlation between the multi-pinholes and the decoding operator must be the delta function. So the URA can provide a… (More)
High performance thin-film transistors were fabricated using a new precursor of pentacene through a multiple spin-heat procedure. High quality pentacene thin films can be prepared by this method and hence a FET device can be made in a top-contact configuration. The device exhibited a remarkable field-effect mobility of 0.38 cm(2) V(-1) s(-1) with an on/off… (More)
