摘要：

(TSM-TTP)(I-3)(5/3) (TSM-TTP: 2,5-bis[4,5-bis(methylseleno)-1,3-dithiol-2-ylidene]-1,3,4,6-trtrathiapentalene) is a one-dimensional organic conductor which undergoes a metal-insulator transition at T(MI)approximate to 20 K. High pressure resistivity, ESR, and static magnetic susceptibility measurements have been carried out to clarify the origin of the metal-insulator transition. The metal-insulator transition temperature is not completely suppressed even under a pressure of 11.8 kbar. The ESR line shape shows no anomaly and the magnetic susceptibility shows a slight increase below 70 K, and remains paramagnetic down to 1.75 K; no evidence of spin-Peierls or antiferromagnetic transition is obtained.
