冠醚化二苯甲酮的合成及其光物理行为

Synthesis and hotophysical Behaviour of Crowned Benzophenones

本文报道采用在多聚磷酸中酰化的方法,合成了冠醚化二苯甲酮1～8。它们与叔胺类共用可能被用作光引发剂。为此,用紫外光谱详细研究了这些化合物及其络合后的光物理行为。还提及化合物3和4作为紫外吸收剂的可能性。

A series of crowned benzophenones(1～2 and 5～8)which may be applied as co-photoinitiators together with tertiary amines,have been synthesized by acylation in PPA.A detailed investigation on the photophysical behaviour of these compuun(?)s and their com-plexation by means of UV spectra has been carried out.The potential of 3 and 4 as UVabsorbers is also mentioned.
