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.
wherein M is a transition metal; A+ 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):
(wherein R1 is an alkyl group having 1 to 4 carbon atoms),
(wherein n is 3, 4 or 5),
(wherein R2 is one of a hydrogen atom and a substitutent having 1 to 4 carbon atoms).
本文提供了一种通式(1)表示的新型取代苯二硫醇金属络合物。该取代的苯二硫醇金属络合物可用作单线态氧淬灭剂和光学数据记录介质本身。
其中 M 是过渡金属;A+ 是季铵基;R 是有机基团,选自由式(i)、(ii)、(iii)和(iv)代表的有机基团组成的组:
(其中 R1 是具有 1 至 4 个碳原子的烷基)、
(其中 n 为 3、4 或 5)、
(其中 R2 是氢原子和具有 1 至 4 个碳原子的取代基)。
