Compounds derived from carbazoles and phenyl benzidines have been used as organic dyes. In fact, due to their chemical structure and their conjugated bonds, they have aroused interest in being studied for their ability to transport electrons, which makes them good candidates to be used in solar cells, which have been called Dye Sensitized Solar Cells and Hole Transport Material. With the knowledge of the thermal properties obtained experimentally through thermal analysis, it is possible to establish the structureenergy relationship of carbazoles and phenylamines, as well as the thermal stability. Based on this, two carbazoles and two phenyl benzidines are feasible compounds with semiconductor capacity to be used in solar cells. The thermal results of the analyzed compounds show that the phenyl benzidine derivatives have a higher molar heat capacity, which is related to the resonance capacity of the electron density of the conjugated double bonds to generate electron density tubes in the in-phase structures solid (Figure 1). To understand the intramolecular movements of N,N’-Bis(3-methylphenyl)-N,N’-diphenyl benzidine and 1,3,5-Tris(diphenylamino)benzene, Raman spectra are presented.
