怎么有分子式查到结构式
有请高人解决C40H26N4O4的结构式,含有五个苯环,四个双键.最好能知道该物质的基本化学性质
我这没有CA查询,

除了极简单的有机物,一般不能从分子式查到结构式,因为同分异构体实在太多了,性质也就不能确定.
这个物质英文名称是
4,4′‐〔(4,4′‐Biphenylylene)bisoxybis(4,1‐phenylene)〕bis〔phthalazine‐1(2H)‐one〕
或:
4,4′‐〔Biphenyl‐4,4′‐diylbis〔oxy(4,1‐phenylene)〕〕bis〔phthalazine‐1(2H)‐one〕
或:
4,4′‐(1,1′‐Biphenyl‐4,4′‐diyl)bis(oxy‐1,4‐phenylene)bis〔phthalazine‐1(2H)‐one〕
你可以再查一下.
我用Scifinder Scholar检索了一下,命中33个化合物,但是所有含5个苯环的,都不只有4个双键。含有5个苯环的此结构式化合物有4种。如果不考虑杂环上的双键的话,的确仅只有一种化合物(882992-79-2)符合你的要求。即(如图): 5(4H)-Oxazolone, 2,2'-[1,4-phenylenebis(methylidynenitrilo-4,1-phenylene)]bis[4-(phenylmethylene) 只有简要性质: Boiling Point:793.9 Density:1.24g/cm3 Flash Point:254.2 只有一篇专利对其有报道: Shakely, Thomas L.; Krutak, James John. Thermoplastic compositions containing UV absorbers for packaging UV sensitive materials.U.S. Pat. Appl. Publ. (2006),29 pp 介绍的摘要如下: Thermoplastic composition and articles containing UV absorbers that protect the articles contents from harmful UV radiation are disclosed as well as methods for making the thermoplastic articles and methods for using the articles to contain and protect materials sensitive to UV radiation. The UV absorbers contain oxazolone and/or azine functional groups that absorb UV radiation and prevent its transmission into the article. Many of the compounds are novel compositions of matter. The generally clear thermoplastic articles of this disclosure are particularly useful for containing a variety of UV sensitive consumer products that would otherwise have to be packaged in opaque containers. The compns. comprise a clear or translucent thermoplastic and an amt. of at least one UV absorber having oxazolone and/or azine functionality sufficient to reduce the transmission of UV radiation. Thus, benzaldehyde 198.6, acetic anhydride 382, hippuric acid 335.4, and sodium acetate 153 g were mixed and heated at 95 in xylene for 3 h to give 375 g 2-phenyl-5-(phenylmethylene)-4(5H)-oxazolone after the workup, which was mixed with PET to give a title compn. 专利地址如下: http://appft1.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PG01&p=1&u=/netahtml/PTO/srchnum.html&r=1&f=G&l=50&s1='20060084732'.PGNR.&OS=DN/20060084732&RS=DN/20060084732
