L-arginine (L-Arg) and L-lysine (L-Lys) are both essential amino acids and paly significant roles in human beings and other living organisms. Therefore, it is necessary to develop the feasible methods with high selectivity and sensitivity for the detection of L-Arg and L-Lys. Herein, aminopyrene modified diacetylene monomer (PCDA-PY) was prepared and incorporated into diacetylene monomer (PCDA) to form polydiacetylene (PDA) vesicles. With the assist of Mg²⁺, PDAs system underwent colorimetric and fluorescent changes upon the addition of L-Arg or L-Lys. The introduction of Mg²⁺ and pyrene moiety makes PDAs system more sensitive toward L-Arg or L-Lys. Furthermore, an “OR AND” logic gate was constructed based on the optical changes of PDAs system with the three elements including Mg²⁺, L-Arg and L-Lys.

L-精氨酸和L-赖氨酸的基于聚二乙炔的比色和荧光探针及其在逻辑门中的应用

L-精氨酸（L-Arg）和L-赖氨酸（L-Lys）都是必不可少的氨基酸，在人类和其他生物中也起着重要的作用。因此，有必要开发一种具有高选择性和灵敏度的可行方法来检测L-Arg和L-Lys。本文中，制备了氨基modified改性的二乙炔单体（PCDA-PY），并将其掺入二乙炔单体（PCDA）中以形成聚二乙炔（PDA）囊泡。在Mg ²⁺的辅助下，PDA系统在添加L-Arg或L-Lys后经历了比色和荧光变化。Mg ²⁺和pyr部分的引入使PDA系统对L-Arg或L-Lys更加敏感。此外，基于PDA系统的光学变化，利用包括镁在内的三个元素，构建了“或与”逻辑门。²⁺，L-Arg和L-Lys。
