Facile construction of fully sp2-carbon conjugated two-dimensional covalent organic frameworks containing benzobisthiazole units

Nature Communications, 2022
Synthesis of fully π-conjugated covalent organic frameworks (COFs) remains still challenging. Here, the authors propose a versatile synthesis method based on Knoevenagel polycondensation for the synthesis of vinylene-linked benzobisthiazole-based 2D COFs.

Fabrication of functional and biodegradable scaffolds using nucleated poly(4-hydroxybutyrate) via 3D printing for bone tissue engineering

Polymer Testing, 2023
Poly (4-hydroxybutyrate) (P4HB) was a new generation of biosourced and biodegradable semi-crystalline polymer. However, due to the low crystallization temperature and slow crystallization rate of P4HB, there were problems such as insufficient cooling and

Science and Technology of Conducting Polymers [PDF]

Europhysics News, 1991
The applicability of the concept of “doping” is the unifying theme which distinguishes a certain class of organic polymers — “conducting polymers” — from all others. Doping results in dramatic electronic and magnetic changes with a concomitant increase in conductivity to, or approaching, the metallic regime.
