Recent advances on visible light Thiophene-based photoinitiators of polymerization

Recent developments in visible light induced polymerization towards its application to nanopores

“…[53][54][55] The combination of visible light induced, free radical polymerization with 3D printing is a rapidly growing research area. 41,56,57 For example, Laleve `e and colleagues 58 used ketone derivatives for a free radical polymerization under 405 nm light and demonstrated 3D printing. Breloy et al 46 used methacrylated quinizarin derivatives to achieve complex 3D biosourced structures under 405 nm light irradiation for 3D-photoprinting technology.…”

Design rules for optimization of photophysical and kinetic properties of azoarene photoswitches

“…Azobenzene is the prototypical photoswitch; its photophysical and energy-storing properties are well-known, and it can be readily synthesized. [1][2][3][4][5][6][7] Azoarenes have been used for applications in materials science [8][9][10][11][12] and photopharmacology. [13][14][15] Azoarene photoswitches are a general class of azobenzene derivatives that offer considerable structural diversity and undergo light-promoted E → Z isomerization when irradiated with ultraviolet to infrared light.…”

Conjugated Polymer Nanoparticles as Visible Light Panchromatic Photoinitiators for 3D Printing of Acrylic Hydrogels

“…The activation of PIS with visible rather than UV photoirradiation is desirable for bioapplications given the harmful effect of the latter toward live cells. 9,10 However, type II PIS are generally not biocompatible because these systems incorporate toxic co-initiators (amines, onium salts, etc.). 11 Moreover, these co-initiators (and their byproducts reaction) are low-molecular-weight molecules that can easily leach out of the resulting polymers and may affect living cells in certain biological applications such as tissue engineering, cell encapsulation, etc.…”
