The development of visible-light 3D printing technology by using water-soluble initiating systems has attracted widespread attention due to their potential applications in the manufacture of hydrogels. Besides, at present, the preparation of water-soluble photoinitiators suitable for visible light irradiation (such as LEDs) still remains a challenge. Therefore, this work is devoted to developing water-soluble photoinitiators (PI)/photoinitiating systems (PIS) upon irradiation with a LED @ 405 nm. In detail, a new water-slightly-soluble chalcone derivative dye [(E)-3-(4-(dimethylamino) phenyl)-1-(4-(2-(2-(2-methoxyethoxy) ethoxy) ethoxy) phenyl) prop-2-en-1-one] was synthesized here and used as a PI with a water-soluble coinitiator, i.e., triethanolamine (TEA) which was also used as an electron donor. When combined together, a charge transfer complex (CTC) formed immediately which exhibited excellent initiating ability for the free radical photopolymerization of poly(ethyleneglycol)diacrylate (PEG-DA). In light of the powerful CTC effect, the [dye-TEA] CTC could not only exhibit enhanced water solubility and mechanical properties but could also be effectively applied for 3D printing. This CTC system is environmentally friendly and cost-saving which demonstrates a great potential to prepare hydrogels via photopolymerization.

Despite the many recent advances in exploiting stoichiometric charge-transfer complexes in visible light promoted single-electron redox reactions, catalytic approaches to charge-transfer complex formation remain limited. This report describes the radical perfluoroalkylation of electron-rich (hetero)arenes and iodoperfluoroalkylation of alkenes and alkynes promoted by a substituted hydroquinone catalyst. Mechanistic and computational studies indicate that the reaction is initiated by the formation of a visible light absorbing halogen bonding complex between the hydroquinone catalyst and the perfluoroalkyl iodide radical precursor.

A pronounced cooperative effect leading to a sharp growth of charge-transfer complexes (CTCs) in the electronic ground state is observed.
