| Abstract |
A method of preparing molecularly imprinted polymers (MIPs) with Zn(II) as a metallic pivot was adopted to solve the problem of imprinting compound with intramolecular hydrogen bonds by forming stronger coordination binding interaction among the template-functional monomer-Zn2+ complex. A ternary porogenic system including dimethyl sulfoxide, dimethylformamide, and room temperature ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate was employed to fabricate imprinted monolith with high porosity and good flow-through properties, in which chicoric acid (CA), zinc acetate, 4-vinylpyridine (4-VP), and ethylene glycol dimethacrylate (EDMA) was the template, metallic ion, functional monomer, as well as crosslinker, respectively. The influence of polymerization factors including the 4-VP-CA ratio, monomer-crosslinker ratio, template-Zn2+ ratio on imprinting factors was systematically investigated. When the ratio of 4-VP to CA was 24:1, the greatest IF value (24.81) was achieved on the CA-MIP prepared with zinc acetate. In addition, off-line SPE with the optimal MIPs monolith led to high purity of CA (98.0% ± 0.5%) from extraction of Cichorium intybus L. roots with the recovery of 77.5% ± 2.5% (n = 6). As a conclusion, the strategy of introducing metal ions as metal pivot to prepare MIPs was a powerful method for the MIPs synthesis to the template molecules with intramolecular hydrogen bonds. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 15 January 2018.
All research outputs
#22,764,772
of 25,382,440 outputs
Outputs from Analytical & Bioanalytical Chemistry
#7,543
of 9,619 outputs
Outputs of similar age
#388,692
of 449,001 outputs
Outputs of similar age from Analytical & Bioanalytical Chemistry
#122
of 169 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 9,619 research outputs from this source. They receive a mean Attention Score of 3.1. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 449,001 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 169 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
