Abstract
Provided are a phenanthroimidazole derivative, and a preparation method therefor, and an application thereof. The phenanthroimidazole derivative has a structural formula as shown in Formula (I), R being an electron donor group, wherein by taking a phenanthroimidazole group containing a trifluoromethyl phenyl group as an electron acceptor, and in virtue of the properties of the specific electron donor group R, the phenanthroimidazole derivative containing a light-absorbing photosensitive group of a series D-π-A structure is synthesized, and can be used as a photoinitiator, which is used in the technical field of UV light-curing systems or 3D printing. The phenanthroimidazole derivative has a certain conjugated chain length, can increase its photon absorption cross section, can serve as a photoinitiator of a UV light-curing system, for initiating a polymerization reaction at a wavelength of 365 nm, and has high polymerization efficiency; a double bond conversion rate of the phenanthroimidazole derivative in 50 s is up to 88.34%.
