    Abstract: Disclosed herein is a novel method for preparing cyclophanes, comprising forming a disulfide cyclophane by contacting a linker moiety which includes two or more thiol groups, with a metal salt and an oxidant. The disulfide cyclophane is then desulfurized to form a thiacyclophane comprising thioether bridges. This thiacyclophane optionally may be further desulfurized to form an unsaturated hydrocarbon cyclophane, which can then be reduced to form a saturated hydrocarbon cyclophane. The various cyclophanes can be synthesized in a ring form, such as a dimer, trimer or tetramer etc., or they can be synthesized in a tetrahedral or larger structure. Also disclosed are novel cyclophanes formed by the disclosed method.

    Abstract: The present invention discloses an oxidized mixed cyclic phenol sulfide which is a mixture of the oxidized cyclic phenol sulfide wherein in is 8 and the oxidized cyclic phenol sulfide wherein m is an integer other than 8, the oxidized cyclic phenol sulfide being represented by the following formula (1): wherein R is a straight or branched alkyl group having 1 to 6 carbon atoms, m is an integer from 4 to 9, and n is 1 or 2; or an oxidized cyclic phenol sulfide of formula (1) wherein m is 8. The present invention also discloses a charge control agent which comprises the above sulfide(s) as the active ingredient; and a toner which comprises the charge control agent, a coloring agent and a binder resin. This charge control agent is particularly useful for color toners, and it speeds up charging risetime, and has a high charge amount and charging characteristics excellent in environmental stability. Further, the charge control agent is safe since it does not have any problem with the waste regulations.

    Abstract translation: 本发明公开了氧化型环状苯酚硫化物，其中在8中的氧化环状苯酚硫化物和其中m为8以外的整数的氧化型环状苯酚硫化物的混合物，氧化的环状苯酚硫化物由下式 （1）表示：其中R是具有1-6个碳原子的直链或支链烷基，m是4至9的整数，n是1或2; 或式（1）的氧化环状苯酚硫化物，其中m为8.本发明还公开了一种电荷控制剂，其包含上述硫化物作为活性成分; 以及包含电荷控制剂，着色剂和粘合剂树脂的调色剂。 该电荷控制剂对于彩色调色剂特别有用，并且其加速时间上升，并且具有高的电荷量和环境稳定性优良的充电特性。 此外，充电控制剂是安全的，因为废物规定没有任何问题。
