4`-formylbenzo-15-crown-5와 RHD, RED의 반응에 의해 새로운 두 종류의 크라운 에테르 RHDC와 REDC를 합성하였다. RHD, RED는 로다민 6G와 hudrazine, ethylenediamine을 이용하여 합성하였다. 합성된 화합물들에 여러 가지 금속 양이온을 첨가하여 선택적인 형광 인식 특성을 알아보고, 형광 센서로서의 가능성에 대해 검토하였다. 합성된 화합물의 금속 인식 특성을 형광스펙트럼으로 측정한 결과 형광이 증가하였으며 Fe3+ 대한 인식이 가장 좋았다.
New two crown ether RHDC and REDC have been synthesized by the reaction of 4`-formylbenzo-15-crown-5 with RHD and RED, respectively. RHD and RED were prepared from the reaction of rhodamine 6G with hydrazine and ethylenediamine, respectively. To investigate the features of selective fluorescence recognition, various cations were added into the synthesized compounds, and studied of there`s possibility as the fluorescent sensors, Metal recognition characteristics of RHDC, REDC and the other compounds were measured with a spectra of fluorometer. Fluorescence intensity were increased and showed the better recognitive ability with Fe3+ than any other cations.
