設計以鄰苯二胺為核心架構的化學感測分子，外層接上咔唑來修 飾核心架構上的共軛系統和推拉電子性，另外在二胺官能基的地方做 乙二胺的延伸，使整體具有一個離子結合位置。先藉由UV-Vis測量 其最大吸收波長 ，接著再用不同金屬離子的無機鹽纇來滴定此化合 物透過UV-Vis來觀察吸收波長變化 。 Synthesis of heavy metal cation sensing molecules based on 0-Phenylenediamine. It possesses conjugate property, and push-pull system. It can be a good Organic Light Emitting Diode. We employ 0-Phenylenediamine’s amino group to synthetize a good binding site. Finally, we titrate with solution which include heavy metal cation following measure the maximum UV- Vis wavelength. We observe color change
