一個由化學物質設計的螢光離子感測器，必須結合受體與發光團兩個部分，分別用於抓取-示現。其中受體擇取離子，可視為控制電子轉移的開關，並影響發光團發出螢光與否。
我們合成一系列以蒽為螢光發射基團的新螢光感測器。並使用多種陽離子做螢光測試，發現在水與二甲基亞碸(DMSO)的混合溶劑系統中，當化合物5加入鉻(Ⅲ)離子，形成錯合物後抑制光誘導電子轉移從而放射出螢光，使螢光強度增強，可達120倍。

The design of fluorescent molecular sensors for chemical species combines a receptor and a fluorophore for a “catch-and-tell” operation. The fluorescence emission depends on combination of the receptor and ion which can be seemed as switch of electron transfer.
We synthesized a series of new fluorescent sensors with anthracene as fluorescence emission group and fluorescent sensors can be used in fluorescence test of different cations. We found that adding Chromium (III) into the compound 5. The formation of the complex inhibits the photoinduced electron transfer. A fluorescence enhancement of about 120-fold was observed for 5-Cr3+ system in a water-DMSO mixed solvent system.
