提出了“有机同秩列”、“有机同秩物”、“有机同秩异构体”等概念体系,并以单取代烷烃同秩物Xi-(CH2)j-H(Xi=F、Cl、Br、I、NO2、CN、NC、OH、NH2、SH、COOH、CHO)为例,对其气相标准摩尔生成焓(△rH■m)、电离能(IP)的结构-性能关系进行了研究,分别对j=2～8的七组同秩物的生成焓及j=2～4的三组同秩物的电离能建立了数学模型:△rH■m(j)=a+b△rH■m(1)+cPEI(R)和IP(j)=a+bIP(1)+bPEI(R),得到了有意义的结果.研究表明,从有机同秩物的角度可以建立一种新的分子结构-性能相关方法,它与有机同系物方法相互独立又互为补充.本文提出的概念体系不仅增加了新的有机化学理论和概念,还为有机物结构-性能变化规律的研究开辟了新视角.
The concept systems of “Organic Rankings”, “Organic Rankings” and “Organic Isomorphisms” are proposed. (N = F, Cl, Br, I, NO2, CN, OH, NH2, SH, COOH and CHO) were used as an example to study their gas phase molar enthalpy (△ rH ■ m), ionization energy (IP) The mathematical model was established for the enthalpy of formation of seven groups of homoplasms with j = 2 ~ 8 and the ionization energies of three groups of homophorsts with j = 2 ~ 4, respectively: △ rH ■ m (j) = A + b △ rH ■ m (1) + cPEI (R) and IP (j) = a + bIP (1) + bPEI (R), and obtained meaningful results.Research shows that from the perspective of organic homology A new molecular structure-property correlation method can be established that is independent and complementary to the organic homologue method.The concept system proposed in this paper not only adds new theories and concepts of organic chemistry, but also studies the structure-property variation of organic compounds Research has opened up a new perspective.
