15 ACS / Proprietary and Confidential / Do Not Distribute
反馈: …这个方法查的很准确。现在有个小问题,我本来有两篇相关的专利,但是查出来的结果中没有,我又按题名搜索,发现专利是有被收录的。那么我这种漏检情况的问题可能出在什么地方呢?… 1、日本专利JP 中记载(CaAl2Si10N16:Eu2+) ILLUMINATION UNIT EQUIPPED WITH AT LEAST ONE LED AS LIGHT SOURCE 2、日本专利JP A中记载(Ca1.5M3Si9N16:Eu2+) Illumination device with at least one LED as the light source ACS / Proprietary and Confidential / Do Not Distribute

16 ACS / Proprietary and Confidential / Do Not Distribute
查找JP 专利,SciFinder的确没有标引 ( CaAl2Si10N16:Eu2+ ),但是标引了其母体物质 CaAl2Si10N16, 并标引Substance role为Uses ACS / Proprietary and Confidential / Do Not Distribute

17 此物质为权利要求中的表格化合物,SciFinder没有全部收录或者标引
ACS / Proprietary and Confidential / Do Not Distribute

18 ACS / Proprietary and Confidential / Do Not Distribute
解决方案: 思路一:通过物质检索母体物质(CaAl2Si10N16),由此获得文献,再通过Refine by Research Topic,限定其描述了Eu,从而获得所需专利结果。 思路二:通过物质检索母体物质(CaAl2Si10N16), 保存为结果集1,然后物质检索Eu,获得的结果集与结果集1取交集,获得所需专利结果。 ACS / Proprietary and Confidential / Do Not Distribute

多氧簇金属:七钼酸铵 H4 N . 1/6 Mo7 O24 ACS / Proprietary and Confidential / Do Not Distribute

21 如何查找MOF化合物,以Cu-BTC为例
ACS / Proprietary and Confidential / Do Not Distribute

22 方法1:若已知物质的CAS号码,物质名称,使用Substance Identifier
ACS / Proprietary and Confidential / Do Not Distribute

23 方法2:已知MOF化合物单元分子式,可以使用分子式检索
ACS / Proprietary and Confidential / Do Not Distribute

24 方法3:已知配合物配体,可以先结构检索配体,然后获得相关配合物
注:此种方法可能结果噪音较多 ACS / Proprietary and Confidential / Do Not Distribute

25 在结果集中通过Analyze by Elements,选择Cu
ACS / Proprietary and Confidential / Do Not Distribute

26 结果会有噪音,可以通过结构等进一步进行筛选
ACS / Proprietary and Confidential / Do Not Distribute

27 方法4:已知MOF化合物单元结构式,可以绘制完整结构进行检索
ACS / Proprietary and Confidential / Do Not Distribute
