摘　　要：环缩醛化合物作为一类具有光敏性的化合物,虽然在上世纪60年代有较多的研究,但由于其吸收波长较窄、引发效率较低等限制,后期研究比较少.但最近5年内,由于对胡椒环等环缩醛化合物的重新认识,尤其是将其作为光聚合引发助剂来提高引发效率或减少引发体系的毒性,获得了光聚合生物材料领域的特别关注.本文对环缩醛类化合物的光聚合行为进行了系统阐述,对当前环缩醛类化合物用作光引发剂及助引发剂的进展也进行了详细介绍.Cyclic acetals, a kind of photo-sensitive compounds, were widely investigated during the 1960s. However, the drawbacks of cyclic acetals, such as the narrow range of absorption wavelength and the low initiation efficiency, had limited the development in the late 20th century. Nevertheless, in the recent five years, cyclic acetals such as 1,3-benzodioxole have drawn renewed attention in photopolymerization, especially in the field of photopolymerized biomaterials, since cyclic acetals could be used as coinitiator so as to increase the initiation efficiency or decrease the toxicity of photoinitiating systenx In this paper, the photopolymerization behavior of cyclic acetals has been systematically described, and the research progress of cyclic acetals as photoinitiator or co-initiator has also been discussed in detail.
