The study of the linear defects and their associations observed in the hexagonal phase of the hexapentoxytriphenylene demonstrates the existence of + π disclinations with molecular columns along evolutes of a circle and confirms the L 6 symmetry of the studied phase. The anchoring energy of the discotic on the glass is estimated (≃ 10 -2 ergs/cm2).L'étude des défauts rectilignes et de leurs associations observés dans la phase hexagonale de l'hexapentoxytriphénylène a permis de montrer l'existence des lignes dièdre S = 1/2 en développantes de cercle et de confirmer la symétrie L 6 de la phase discotique. L'énergie d'ancrage du discotique sur le verre non traité est évaluée (≃ 10 -2 ergs/cm2)
