摘　　要：孔道结构氧-钒基磷酸盐具有丰富而复杂的结构化学特点及特殊的吸附、离子交换、择形催化,以及非线性光学、电磁学等性能,由此成为微孔材料领域研究的热点之一。本文综合评述了孔道结构氧-钒基磷酸盐体系的合成方法、模板与结构导向机理、晶体结构与晶体化学、结构热稳定性等的研究现状,重点讨论了有机模板引导合成的O rgn+-V-P-O相及其模板驱除方法,并提出了存在的问题及今后的研究方向。Extensive studies have been devoted to the synthesis and characterization of V-P-O system because of not only their rich and complex structural chemistry, but also their relevance to adsorptive, catalytic ,optical and magnetic properties. The recent development in the preparation, characterization, and crystal chemistry and thermal stability of oxo-vanadium phosphates with open framework is covered in this review. The emphatical illumination is focused on the Org^n＋ -V-P-O phases and the removal of organic templates occluded in their channels. The future research directions and the potential approaches to the enhancement of the structures stability of Org^n＋ -V-P-O system are proposed.
