  摘要：

  通过UV-Vis，IR和EPR光谱研究了在3-5 K下在氩气中分离的基质中二苯卡宾5的光化学性质。尽管卡宾5证明对宽带UV辐射稳定，但在445 nm二极管激光器的强光照射期间，它会缓慢重排为1-苯基-1,2,4,6-环庚酸酯8。未观察到其他中间体。在将5重排为芴7的拟议机制中，丙二烯8是关键中间体。版权所有©2014 John Wiley＆Sons，Ltd.

  at 390 nm, interpretable in terms of a diphenyl carbene radical-cation ([(C6H5)2C]+˙). A phenyldiazomethane radical cation ([C6H5CHN2]+˙) and a phenylcarbene radical-cation ([C6H5CH]+˙) have absorption bands at 515 and 475 nm, respectively. The e.s.r. spectrum of [(C6H5)2CN2]+˙ cations, produced by the radiolysis of CCl3F–(C6H5)2CN2(0.2 mol %) mixtures at 77 K, shows a broad singlet spectrum. Upon irradiation

  The triplet-triplet fluorescence of perprotonated and perdeuterated diphenylcarbene (DPC-h10 and -d10) in n-hexane at 4.2-25 K are both composed of a sharp spectrum and a broad blue-shifted one. They are attributed to two different conformers, the sharp spectrum corresponding to DPC in a quasi-planar geometry. The excitation spectra of both emissions consist of broadbands with a large Stokes shift. A detailed CS-INDO CI investigation (configuration interaction based on an intermediate neglect differential overlap method adapted to conformation and spectroscopy problems) is performed for three different geometries of DPC having C2v, C2, and C1 symmetries. The computed triplet-triplet transition energies which indicate an hypsochromic shift going from planar C2v to nonplanar C1 structures compare favorably with the experimental data. The fluorescence decays of DPC-h10 and -d10 are nonexponential and attributed to the emission from different sublevels of the first excited triplet state. The measured decays of the broad fluorescence are longer than those of the sharp one. This is in agreement with CS-INDO CI calculations which predict a decrease of the oscillator strength of the T0-T1 transition going from C2v to C1 structures, as due to the inversion between the two excited triplets corresponding to the n-pi*1 and npi*2 configurations. The zero-field splitting (ZFS) parameter D(T1) of DPC in the first excited triplet T1 has been estimated from the magnetic field effect on the fluorescence decays. D(T1) = 0.007 and 0.20 cm-1 for measurements carried out respectively on the sharp and on the broad fluorescence. Tentative ZFS calculations give D(T1) = 0.01 55 cm-1 for the C2v structure and D(T1) = 0.01 15 cm-1 for the C1 structure. The measured and calculated D(T1) values are always smaller than the D(T0) = 0.405 cm-1 value of DPC in the ground triplet state, which indicates the delocalization of the pi electron density onto the aromatic rings upon excitation. It is therefore reasonable to detect a specific chemistry of this carbene in the presence of an intense laser which creates a high concentration of DPC in the first excited triplet T1.

  The present disclosure describes non-classical (e.g., quantum) computing systems and methods that utilize dopant molecules contained in host materials as qubits. The dopant molecules generally comprise ground-state triplet (GST) molecules, such as carbenes or nitrenes. The host materials generally comprise organic molecules. Precursors to the dopant molecules can be embedded in the host materials and then subjected to ultraviolet (UV) or visible light to form dilute molecular crystals comprising the dopant molecules embedded in the host materials. The triplet sub-levels of the dopant molecules may be manipulated using electromagnetic (EM) radiation such as optical, radiofrequency (RF), and/or microwave (MW) radiation to conduct non-classical computing operations.
