Field-independent grating formation rate in a photorefractive polymer composite sensitized by CdSe quantum dots

A photorefractive polymer composite sensitized by CdSe quantum dots was described. In contrast to most other photorefractive polymers reported, the hologram formation rate was observed to be independent of applied field. This result was explained by the low saturation field calculated for this material.

Core - Shell and hollow nanocrystal formation via small molecule surface photodissociation; Ag@Ag2Se as an example

Metallic Ag nanoparticles have been converted to Ag2Se nanoparticles at ambient temperature and open atmosphere by UV photodissociation of adsorbed CSe2 on the Ag core surface. The photolysis could be prevented at any stage yielding Ag@Ag2Se core - shell structures of different thickness. Depending on the initial Ag nanoparticle size, either hollow or filled nanocrystals of Ag2Se could be prepared. The Kirkendall effect has been proposed to account for the formation of hollow nanoparticles. A coated-sphere Drude model has been used to explain the redshift of the Ag plasmon band as a function of the Ag 2Se shell thickness as well as to provide the first estimates of the wavelength-dependent dielectric function of Ag2Se. This photochemical method might be especially promising for carrying out a direct room-temperature phototransformation of metallic into semiconductor nanostructures already assembled on surface templates.

The elusive ethenediselone, Se=C=C=Se

The neutral ethenediselone, Se=C=C=Se, has been characterised by neutralisation-reionisation mass spectrometry, which implies a minimum lifetime of the order of microseconds. Tetraselenafulvalene 1 and tetramethyltetraselenafulvalene 2 were used as precursor molecules. Flash vacuum thermolysis (FVT) of these compounds with isolation of the products in Ar matrices permitted the identification of ethyne, 2-butyne, CSe2, and selenoketene, H2C=C=Se, but at best traces of Se=C=C=Se survived the FVT/matrix isolation experiment. Multiconfigurational calculations indicate that Se=C=C=Se is a ground state triplet molecule with a very small singlet-triplet gap.

FTIR studies of O(3P) atom reactions with CSe2, SCSe, and OCSe

The overall rate coefficients of the reactions of CSe2, SCSe, and OCSe with O(3P) atom have been determined to be kCSe2 = (1.4 ± 0.2) × 10-10 cm3 molecule-1 s-1, kSCSe = (2.8 ± 0.3) × 10-11 cm3 molecule-1 s-1, and kOCSe = (2-4 ± 0.3) × 10-11 cm3 molecule -1 s-1 at 301-303 K using Fourier transform infrared (FTIR) absorption spectroscopy. The measurements have been accomplished by calibrating against the literature value of the rate coefficient for O( 3P) with CS2 (4 × 10-12 cm3 molecule-1s-1). A product channel giving OCSe in 32.0 ± 4.2% yield has been found for the O + CSe2 reaction. Although CO was also detected, its generation could be attributed to subsequent reactions of OCSe with O atoms. The corresponding reaction for O + SCSe gives OCS and OCSe as observable products, with their yields given as 32.2 ± 4.5 and 30.2 ± 3.3%, respectively. Computational studies using UB3LYP/aug-cc-PVTZ methods have been used particularly to determine the reaction pathways for the channels in which OCS or OCSe is produced.

Gas Phase Reactions, 40. Selenoformaldehyde: Highly Correlated Wave Function and Photoelectron Spectroscopic Evidence

A systematic search for the unknown molecule selenoformaldehyde, H2C=Se, starts with the precalculation of its ionization pattern from ab-initio-PNO-CI and CEPA wave functions.The selenium precursors H3CSeSeCH3, H3CSeCN, H3CSeCl, and (H2CSe)3 are pyrolyzed in a flow system under PE spectroscopic real-time analysis: Applying "computerized spectra stripping" to the PE spectra of the pyrolysis mixtures, an ionization pattern can be extracted which correlates satisfactorily with the quantum chemical prediction for H2C=Se.To further support the assignment, selenoacetaldehyde, CH3CH=Se, and selenocarbonyl difluoride, F2C=Se, are prepared by thermal monomerization of 3 and (F2CSe)2, respectively.

Preparations and 1H, 13C, and 31P nuclear magnetic resonance studies of some N,N-dialkyldiselenocarbamate complexes and their phosphine derivatives. X-ray crystal structure of Pt(Se2CN(i-Bu)2)2

A convenient synthesis of CSe2 is reported which can be used to prepare dialkyldiselenocarbamates. The 1H, 13C, and 31P NMR spectra of about 25 derivatives containing the metal ions Zn(II), Ni(II), Pd(II), Pt(II), Pt(IV), and Co(III) are reported. The single-crystal X-ray structure of monoclinic Pt(Se2CN(i-Bu)2)2 (a = 6.736 (1) ?, b = 12.357 (2) ?, c = 15.496 (4) ?, β = 99.03 (2)°) establishes the coordination geometry to be the same as that found1 for the Pt(S2CNEt2)2 analogue. The average Pt-Se distance is 2.427 (3) ?, an increase of ～0.11 ? over the Pt-S distance, similar to the increase observed for Ni-Se over Ni-S.

Molecular Quadrupole Moment and Magnetic Anisotropy of Carbon Diselenide

Measurements of the infinite-dilution molar Kerr constant, field-gradient birefringence constant and Cotton-Mouton constant of carbon diselenide as a solute in carbon tetrachloride at 298 K are reported.From an analysis of the observations, the molecular quadrupole moment, Θ, and the magnetic anisotropy, Δχ, emerge as (+15.4 +/- 2.7) * 10-40 C m2 and (-19.6 +/- 2.6) * 10-5 J T-2 mol-1, respectively.Trends in these and related electric and magnetic properties are considered for the sequence of six linear triatomic molecules of formula XCY (X, Y = O, S, Se).
