The synthesis of Ag(CNAr)2BF4, Ag(CNAr)2NO3, AuCl(CNAr), CuCl(CNAr), [CuCl(CNAr)2]2, Fe(CO)4CNAr, trans-[PdI2(CNAr)2], and trans-[PtI2(CNAr)2] complexes containing the fluorous isocyanide ligand CNAr [Ar = 4-F(CF2)8(CH2)4OC6H4] and the examination of the mesomorphic properties of these novel fluorous organometallics are reported. The fluorous isocyanide ligand is mesomorphic, as opposed to its hydrocarbon
Ag(CNAr)2BF4、Ag(CNAr)2NO3、AuCl(CNAr)、CuCl(CNAr)、[CuCl(CNAr)2]2、Fe(CO)4CNAr、反式-[PdI2(CNAr)2]的合成,和含有氟异氰化物配体 CNAr [Ar = 4-F(CF2)8(CH2)4OC6H4] 的反式-[PtI2(CNAr)2] 配合物,以及对这些新型氟有机金属化合物的介晶性质的检查。与其碳氢化合物类似物相反,氟异氰化物配体是介晶的。一般来说,与其碳氢化合物类似物相比,疏氟效应增强了所研究的有机金属/异氰化物配合物中的微观偏析。含氟中间相在更宽的温度范围内稳定并表现出更高的转变温度。 (© Wiley-VCH Verlag GmbH & Co.
