TG-DTA Measurements of Inclusion Compounds Synthesized Using Organic 1-D Porous Materials and Organic Radicals

Abstract

The current topics of inclusion compounds (ICs) synthesized using organic 1-D porous materials and organic radicals, as well as on the TG-DTA measurements of ICs are reviewed. In these ICs, organic 1-D porous materials, such as tris(o-phenylenedioxy)cyclotriphophazene (TPP) and 2,4,6-tris-4-(chlorophenoxy)-1,3,5-triazine (CLPOT), are used as templates to align stable organic radicals in a 1-D manner based on host-guest interactions. Several TG-DTA measurements of [(organic 1-D porous materials)/(organic radicals)] ICs, such as [(TPP)₂/(DTBN)_1.25] and [(CLPOT)₂/TEMPO] ICs, have been explained in detail (DTBN = di-t-butyl nitroxide radical, and TEMPO = 2,2,6,6-tetramethyl-1-piperidinyl-1-oxyl radical). From the results of TG measurements, the inclusion of organic radicals in TPP or CLPOT nanochannels and the amount of guest radicals are confirmed. These results are available to design and construct a new “organic” magnet.
