Some unsymmetrical nickel 1,2-dithiolene complexes as candidate materials for optics and electronics

摘要

The unsymmetrical complexes Ni(tmedt)(dddt), Ni(dpedt)(dddt), Ni(tmedt)(dmit), and Ni(dpedt)(dmio) (where tmedt is trimethylene-ethyl-enedithiolate, dddt is 5,6-dihydro-l,4-dithin-2,3-dithiolate, dmit is l,3-dithiol-2-thione-4,5-dithiolate, dpedt is diphenyl-ethylenedithiolate, and dmio is l,3-dithiol-2-one-4,5-dithiolate) were prepared and their structural and physical properties investigated. The results were compared with those obtained from similar unsymmetrical and the corresponding symmetrical complexes. The new complexes were found to be stable in air and exhibit the necessary structural and physical properties in order to be candidate materials for optical and electronic devices.
