ABSTRACT:
Disclosed are (i) a boron-dipyrrin compound having thienyl groups, (ii) a preparation method thereof and (iii) a chemosensor comprising the boron-dipyrrin compound having thienyl groups. More particularly, the present invention provides a boron-dipyrrin compound having thienyl group, furyl (OC4H3) group or selyl (SeC4H3) group, which is represented by the following formula (1), a preparation method thereof and a chemosensor comprising the above boron-dipyrrin compound having thienyl groups, characterized in that the chemosensor exhibits variations in colors and fluorescent properties caused by reaction of the boron-dipyrrin compound with metal ions, including, but not limited to, Cu2+and Hg2+:in-line-formulae description="In-line Formulae" end="lead"?3-(R)-4,4-di(R)-8-(R)-4-bora-3a,4a-diaza-s-indacene formula (1)in-line-formulae description="In-line Formulae" end="tail"?wherein R is any one selected from 2-thienyl group and 3-thienyl group.
