  The self-assembly of di-pyrene-substituted γ-CD in water showed significantly high chiroptical activities and gave gabs and glum values up to 4.3×10−2 and 5.3×10−2, respectively. Meanwhile, it provided remarkable chiral emission performance, with the BCPL and BiCPL values reaching 338.6 M−1 cm−1 and 169.3 M−1 cm−1, respectively.

  An accelerated method of orthokeratology includes the steps of softening of the cornea with a softening agent, applying a mold to reshape the cornea to a desired anterior curvature, and rapidly restabilizing or “fixing” the corneal tissues so that the cornea retains its new configuration. A chemical softening agent, such as glutaric anhydride is applied to the cornea to soften the cornea, after which a specially designed mold of predetermined curvature and configuration is applied to the cornea. Slight downward pressure is applied to the mold for a predetermined period of time to re-shape the cornea. The mold is maintained in position while a stabilizing agent, such as a UV light source, is positioned above the mold. The stabilizing agent, i.e. UV light, is applied to the cornea for a predetermined time, wherein the stabilizing agent immediately restabilizes the corneal tissue so that the cornea immediately retains its shape upon removal of the mold. The stabilization process can also be used for patients having already undergone traditional orthokeratology to eliminate the need to continue wearing a retainer to maintain the shape of the cornea.

  角膜矫形术的加速方法包括以下步骤：用软化剂软化角膜，使用模具将角膜重塑成所需的前弧度，并迅速重新稳定或 "固定 "角膜组织，使角膜保持新的形态。在角膜上涂抹化学软化剂（如戊二酸酐）以软化角膜，然后在角膜上涂抹专门设计的具有预定弧度和结构的模具。在预定时间内对模具施加轻微的向下压力，以重新塑形角膜。将稳定剂（如紫外线光源）置于模具上方时，模具将保持在原位。将稳定剂（即紫外线）照射到角膜上，持续预定的时间，其中稳定剂会立即重新稳定角膜组织，使角膜在移除模具后立即保持其形状。稳定过程也可用于已接受传统角膜矫形术的患者，使其无需继续佩戴保持器来保持角膜的形状。

  By reacting with a rigid disulfonyl chloride, beta-cyclodextrin 6-tosylate is readily disulfonylated for the first time to give 6(A),6(C),6(E)-trisulfonylated beta-cyclodextrins in good yields, which represents an efficient novel method for the regio-selective preparation of 6(A),6(C),6(E)-trifunctionalized beta-cyclodextrins.
