NOVEL NONCENTROSYMMETRIC STRONTIUM-ORGANIC FRAMEWORK WITH HIGH THERMAL STABILITY

摘要

PURPOSE: A novel non-centrosymmetric strontium-organic backbone structure compound with excellent thermal stability is provided to be applied in various fields by showing excellent thermal stability. CONSTITUTION: A novel non-centrosymmetric strontium-organic backbone structure compound has thermal stability at 25-550 deg. Celsius and one-dimensional nano-tube type channel structure. The channel is formed by connecting SrO8, SrO9, NO3 and benzenetricarboxylic acid group through oxygen atoms. The channel shares one side by the SrO8 polyhedron and SrO9 polyhedron and forms helix chain. The helix chain has a tubular structure which is formed by connecting SrO9, carboxylic acid organic linker and NO3 group through the oxygen atoms. The strontium-organic backbone structure compound includes structure units represented by chemical formula 1. The chemical formula 1 is as follows: (Sr2(C6H3(CO2)3(NO3))-DMF). The compound is crystallized at the non-centrosymmetric hexagonal space group, P-62 c (No. 190).
