Abstract
Description
式1又は式2で表される、
ことを特徴とする。
本発明の第1の観点に係る蛍光発光性化合物を試料に添加して前記蛍光発光性化合物と前記試料中の水とを反応させ、
紫外線を照射して前記蛍光発光性化合物が発する蛍光の強度を測定して前記試料中の水分量を検出する、
ことを特徴とする。
上述した蛍光発光性化合物を用いて、以下のように有機溶剤や固体材料等の試料中に含まれる微量水分を検出できる。
NaH0.08g(2.1mmol)を添加し、室温で1時間撹拌した。
その後、2−ブロモメチルフェニルボロン酸ピナコールエステル1.0g(3.37mmol)をゆっくり加えながら室温で1時間撹拌した。
反応終了後、反応溶液を減圧濃縮して塩化メチレン−水で抽出・洗浄した後、減圧下で濃縮した。
得られた濃縮物をカラムクロマトグラフィー(展開溶媒:塩化メチレン:メタノール=10:1)により分離精製し、化合物1(0.08g,収率:22%)を得た。
M.p.52−55℃;
IR(ATR):ν=2976(m),1343(s),1142(m)cm−1;
1HNMR(400MHz,[D2]dichloromethane,25℃,TMS)δ=1.27(s,12H,CH3×4),2.17(s,3H,CH3),4.0(s,2H,CH2),4.36(s,2H,CH2),7.26−7.30(m,1H),7.38−7.47(m,6H),7.8(d,J=8.2Hz,1H),7.96−7.99(m,2H),8.34(dd,J=1.9and8.9Hz,2H),8.38(s,1H);
HRMS(APPI):m/z(%):438.2597(100)[M+H+].
得られた化合物1を用いて、各種溶液の水分量の検出を行った。
測定装置:HITACHI F−4500 測定条件:励起波長(光照射波長):366nm スキャンスピード:1200nm/min 励起側スリット:5.0nm 蛍光側スリット:5.0nm ホトマル:400V レスポンス:0.004s
なお、それぞれの検出限界及び定量限界は以下の式31及び式32を用いて算出した。
検出限界=3.3σ/slope・・・(式31)
定量限界=10σ/slope・・・(式32)
式31及び式32中、σはブランクの標準偏差、slopeは図17及び図18それぞれの検量線の傾きである。
