Multichannel Chromogenic and Chiral Anions Recognition by Imidazolium Functionalized BINOL Derivatives

引用

Chinese Journal of Chemistry 2013年第5期31卷 641-650页

作者： Qiaosen Lu Jiting Hou Jian Wang Bangyu Xu Ji zhang xiaoqi Yu Key Laboratory of Green Chemistry and Technology Ministry of Education College of Chemistry Siehuan University Chengdu Sichuan 610064 China

New imidazolium/benzimidazolium-containing receptors （R）-1-（R）-6 were developed as multifunctional re- ceptors for both chromogenic and chiral anion recognition through multichannel. The fluorescence spectra of （R）-1 showed a distinct and intense peak at 454, 474 nm with AcO- and F-, respectively, indicating that （R）-1 can be ap- plied to the detection of fluoride and acetate ions by naked eye. Receptor （R）-5, containing a lipophilic dodecyl ap- pendage at imidazolium nitrogen, exhibited larger fluorescent responses than （R）-1. The ratio of fluorescence en- hancement for （R）-5 with AcO- （I460/I369= 16） and F- （I485/I369= 11） was 32-fold and 18-fold over （R）-1 with AcO- （1454/I369=0.5） and F （I474/I369=0.6）, respectively. Less electron-deficient benzimidazolium receptor （R）-2 only gave fluorescence enhance at 555 nm for F. Only chelation enhanced quenching （CHEQ） effect was obtained in the case of mono-imidazolium receptor （R）-4. Furthermore, （R）-I and （R）-5 displayed a remarkable binding ability for the t-Boc alanine anion with interesting enantioselectivity [KL/KD=4.5 for （R）-1 and 4.1 for （R）-5）], whereas only negligible enantioselectivity ability （KL/KD = 1.1） was obtained by using C1 symmetric receptor （R）-4.

对东亚夏季季风(EASM)模拟的评估可以提高我们对亚洲季风动力和气候模拟的理解.在这项研究中,通过使用中国科学院(CAS)全球海洋-大气-陆地系统(FGOALS-f3-L)模式参加的第六次耦合模式相互比较计划(CMIP6)中的大气模式相互比较计划(AMIP)和历史(historical)试验,明确了EASM的年际变率的模拟能力.通过多变量经验正交函数(MV-EOF)分析发现,观测的EASM的主导模态为西太平洋上的太平洋-日本模态,并伴有局部反气旋异常.主导模态的方差贡献率为24.6%.历史(historical)试验可以基本再现这种空间模态,其方差贡献率较AMIP试验更接近于观测.与AMIP试验相比,历史(historical)试验还能更好地模拟EASM变率的时间频率.然而,由于历史(historical)模拟没有在积分开始时应用初始化过程,而AMIP试验受到海表面温度(SST)的约束,因此主成分(PC1)的位相在历史(historical)试验中没有得到较好地再现.进一步分析发现,印度洋和西太平洋热带地区的海气相互作用对EASM的模拟非常重要,而EASM气候变率的模拟可能与厄尔尼诺-南方涛动(ENSO)的模拟能力有关,这值得进一步分析.
