Description

technical field

[0001] The invention belongs to the field of organic chemistry, and in particular relates to a 9-phenylacridine macromolecular photosensitizer, a preparation method thereof, and an application of the photosensitizer in the field of photocuring. Background technique

[0002] Acridine compounds are macrocyclic conjugated systems with a rigid planar structure and strong fluorescence properties. They are good fluorescent reagents and can be used as photoinitiators in photopolymerization systems, and can also be used as sensitizers to initiate photoinitiation. agent for photopolymerization. 9-Phenylacridine is a derivative of acridine, which belongs to the biphenyl structure. Under ultraviolet light, X-rays or light, it can initiate photocurable materials (photocurable coatings, photocurable coatings, Ink and photoresist, etc.) are cross-linked and cured, and are stable in nature, and have good photosensitive properties in photo-curable materials composed of unsa...
