A novel substituted benzenedithiol metal complex represented by the general formula (1) is provided. The substituted benzenedithiol metal complex is useful as a singlet oxygen quencher and as an optical data recording medium per se. ##STR1## wherein M is a transition metal; A.sup.+ is a quaternary ammonium group; and R is an organic group selected from the group consisting of organic groups represented by the formulae (i), (ii), (iii) and (iv): ##STR2## (wherein R.sup.1 is an alkyl group having 1 to 4 carbon atoms), ##STR3## (wherein n is 3, 4 or 5), ##STR4## (wherein R.sup.2 is one of a hydrogen atom and a substitutent having 1 to 4 carbon atoms).
提供了一种由通式(1)表示的新型取代苯二硫醇金属配合物。该取代苯二硫醇金属配合物可用作单线态氧猝灭剂和光学数据记录介质。其中,M为过渡金属;A.sup.+为季铵基团;R为从由式(i)、(ii)、(iii)和(iv)表示的有机基团组成的群体中选择的有机基团:##STR2##(其中R.sup.1是具有1至4个碳原子的烷基基团),##STR3##(其中n为3、4或5),##STR4##(其中R.sup.2是氢原子或具有1至4个碳原子的取代基之一)。
