  Spectroscopy and kinetics of dithiophosphinate radicals coordinated with dithiophosphinate Ni(II) complex

  摘要：

  The laser flash photolysis was used to study the mechanism of photochromic transformations for solutions of phosphinate disulfide ((S2P(i-Bu)(2))(2) equivalent to (S2PR2)(2)) and Ni(S2P(i-Bu)(2))(2)(Ni(S2PR2)(2)) complex in acetonitrile. Under the excitation of an XeCl excimer laser (308 nm), this system manifests transient absorption in the visible and UV ranges which vanishes over a millisecond time domain. The cycle of phototransformations can be repeated without degradation of the optical spectrum of the solution. The process is initiated by photodissociation of a disulfide molecule into two S-radicals ((S2P)-S-.(i-Bu)(2) equivalent to (S2PR2)-S-.). The radical with a constant of 2.5 x 10(9) M-1 s(-1) enters the coordination sphere of Ni(S2PR2)(2) complex to form the radical complex (R2PS2.)Ni(S2PR2)(2). When analyzing the kinetics of changes in the optical density of transient absorption, it is assumed that coordination of the second radical with a constant of 1.5 x 10(10) M-1 s(-1) results in the formation of the secondary or biradical complex (R2PS2.)(2)Ni(S2PR2)(2). The radical complexes dissociate with a radical escaping from the coordination sphere with rate constants equal to 7.5 x 10(3) s(-1) and 7 x 10(2) s(-1) for mono- and biradical particles, respectively. As a result. the system regains its initial state due to recombination of (S2PR2)-S-. radicals into initial disulfide. (C) 2003 Elsevier Science B.V. All rights reserved.

  摘要：

  激光闪光光解法已被用于记录由二苯二硫，全氟二苯二硫，全氟-2,2'-二萘二硫，二异丙基二黄原和双（二异丁基硫代-磷酰基-二硫）的光解形成的含硫自由基的光谱。吸收带的消光系数由S-自由基与稳定的硝酰基自由基反应确定。对于所有自由基，该反应的速率常数均为接近10 9 M -1 s -1并成功地与重组反应竞争。在硝酰自由基的光谱中窄且强的吸收带的存在以及反应产物中没有吸收的吸收使得人们可以准确地确定S-自由基的吸收带的消光系数。

  nitroxyl radical. The rate constant of this reaction was for all radicals close to 109 M−1 s−1 and successfully competes with the reaction of recombination. The presence of a narrow and strong absorption band in the optical spectrum of a nitroxyl radical and the absence of absorption in the reaction products allows one to accurately determine the extinction coefficients of the absorption bands of S-radicals
