Recent advances on visible light Thiophene-based photoinitiators of polymerization

Visible light photopolymerization has given a revival of interest to due its recent use in 3D printing. With aim at developing visible photoinitiating systems, structures disconnected from the traditional photoinitiators are more and widely examined. Besides, several parameters such as excited state lifetimes, redox properties or molar extinction coefficients newly prepared have be considered order efficiently interact with different additives introduced into photocurable resins. In this field, thiophene is extensively used Organic Electronics low oxidation potential, facile chemical modification possibility design chromophores absorbing all over range. Considering numerous derivatives that been years, was thus candidate choice for polymerization. Over thiophene-based greatly evolved Type I II notably developed. review, an overview advances concerning provided. To evidence these structures, comparisons reference systems
