说明

General description

二甘醇酐(DGA)来自二甘醇酸，以其聚酯和聚酰胺类合成能力著称。二甘醇酐具有低分子量和羟基、胺基带来的高反应性，适于作为聚合物生产的中间体。它可促进交联网络的形成，增强聚合物的机械特性。

Application

二甘醇酐可用于：

作为原料合成生物基聚酯和聚酯酰胺，赋予优异的热稳定性和良好的有机溶剂溶解性。
功能化修饰聚对苯二甲酸乙二酯(PET)纳米纤维，用于稀土元素回收。在水溶液稀土元素离子回收中，二甘醇酐表现快速的结合动力学和高选择性，可增强金属吸附。
作为前体制作可降解聚酯网络涂层，用于防止医疗器械表面发生生物污染。

Fabrication of porous covalent organic frameworks as selective and advanced adsorbents for the on-line preconcentration of trace elements against the complex sample matrix.

Jing-Min Liu et al.

Journal of hazardous materials, 344, 220-229 (2017-10-19)

Herein, for the first time, the typical porous Covalent Organic Frameworks (COFs) CTpBD with superior chemical stability and large surface area were applied as sorbents for solid phase extraction of trace ions via flow injection followed by inductively coupled plasma

Heterotelechelic polymer prodrug nanoparticles: Adaptability to different drug combinations and influence of the dual functionalization on the cytotoxicity.

Daniele Vinciguerra et al.

Journal of controlled release : official journal of the Controlled Release Society, 295, 223-236 (2019-01-07)

Well-defined, heterotelechelic polymer prodrugs for combination therapy were synthesized by using a combination of the "drug-initiated" nitroxide-mediated polymerization from a gemcitabine-alkoxyamine initiator and the nitroxide exchange reaction using TEMPO-bearing drugs to end-cap the drug-polymer chain-end by a second drug. This

Electrochemiluminescence sensor based on upconversion nanoparticles and oligoaniline-crosslinked gold nanoparticles imprinting recognition sites for the determination of dopamine.

Ying Gu et al.

Biosensors & bioelectronics, 128, 129-136 (2019-01-19)

For the determination of dopamine (DA) in serum samples, a quenching-type electrochemiluminescence sensor (MIECLS) was constructed in this study. Upconversion nanoparticles (UCNPs) enhanced by covalent organic frameworks (COFs)-based hybrid and oligoaniline-crosslinked gold nanoparticles (AuNPs) imprinting recognition sites were introduced in
