unsymmetrical salan fluorescent sensors 2a and 2b have been designed and synthesized. The chiral recognition of N-Boc-protected amino acids by 2a and 2b has been investigated. Sensor 2a possesses higher sensitivity and enantioselectivity than sensor 2b does. Job analysis and nonlinear regression results show that 2a can form a 1:1 stoichiometric complex with a N-Boc-protected amino acid. The obtained response
已经设计并合成了新颖的不对称的萨兰荧光传感器2a和2b。已经研究了2a和2b对N -Boc保护的氨基酸的手性识别。传感器2a比传感器2b具有更高的灵敏度和对映选择性。作业分析和非线性回归结果表明2a可以与N -Boc保护的氨基酸形成1:1的化学计量配合物。获得的响应选择性和缔合常数表明2a是对N的高度对映选择性和灵敏的荧光传感器-Boc保护的氨基酸。
