摘要:

A colorless toluene solution of benzo[1,2,3-kl:4,5,6-k′l′]dixanthene endoperoxide (BDXepo)1slowly changes to red BDX2, by refluxing at 110°C in toluene. However, in the presence of HCl,2was formed more rapidly from1even at room temperature. A novel dosimetry system was proposed using1and acid generating materials such as chlorinated alkanes. A chloroform solution of1([1] = 1.0 × 10−3M) gave red color of2after irradiation with γ ray at 73 Gy.
