BF_(3)·Et_(2)O促进的双烯酮-酚重排合成具有聚集诱导发光(AIE)效应的磷杂七元环化合物

BF_(3)·Et_(2)O Promoted Dienone-Phenol Type Rearrangement to Synthesize Phosphepine with Aggregation Induced Luminescence(AIE)Effect

磷杂环庚三烯类化合物作为一类新兴的发光分子吸引了人们研究的兴趣.因其合成路线非常有限,对其结构与发光性能相关性的探索还远远落后于相应的磷杂五、六元环类化合物.双烯酮化合物在酸或碱的促进下发生重排反应被广泛用于酚类化合物的制备.利用螺环双烯酮磷杂六元环化合物在BF_(3)·Et_(2)O作用下发生双烯酮-酚重排反应合成了一系列具有聚集诱导发光(AIE)效应的磷杂七元环化合物.

Very recently,phosphepines has emerged as a new luminogen.Further explorations of this new motif in optical materials have been hampered by the lack of general and practical methods for their synthesis and derivation.The rearrangement of dienones promoted by acid or base is widely used in the preparation of phenols.A series of phosphepines with aggregation induced luminescence(AIE)effect were synthesized by the dienone-phenol rearrangement reaction of spirodienone six-membered phosphacycles in the presence of BF_(3)·Et_(2)O.
