Three dimeric molecules based on trioxothioxanthene and benzotriazole moieties were synthesized by alkylation and esterification reactions. The chemical structures of the compounds were confirmed by (HNMR)-H-1, IR spectroscopies and mass spectrometry. Dilute solutions of trioxothioxanthene and benzotriazole-based compounds in THF absorb electromagnetic radiation in the region of 230-320nm. 1,10-Bis-(9,10,10-trioxothioxanthen-3-yl-carboxy)decane can be transformed into the glassy state with the glass transition temperature of 35 degrees C. It is capable of transporting negative charges. Electron drift mobility in the layers of trioxothioxanthene-based twin compound molecularly dispersed in PC-Z approaches 10(-6)cm(2)/Vs at an electric field of 1x10(6)V/cm.
