초록
본 연구는 다양한 치환기를 포함하고 있는 3종의 보레인 화합물을 합성하고, UV/Vis 하에서 합성된 화합물이 내는 흡광을 이용하여 유기 용매 하에서 매우 적은 농도로 존재하는 불소 이온($F^-$)의 검출에 적용하고자 하는 것이다.
We propose a research for detection of the fluoride ion using borane compounds. Based on the Lewis acid-base reaction, we discussed the fundamental of sensing for fluoride ion. One of the important aspects in the chemistry of organoboranes is their behaviors as Lewis acids, which is a result of the vacant $2p_{\pi}$ orbital on the tricoordinate boron center. The electronic interaction between boron atoms and ${\pi}$-orbitals of donor molecules, constructed from the carbon 2p orbitals, is generally strong. Boron atoms can reach the desired octet configuration either through ${\pi}$-overlap with a suitable X or through formation of Lewis acid-Lewis base complexes.
