PROBLEM TO BE SOLVED: To provide a new organic compound with which problems caused by the intermolecular interaction of derivatives is solved in polycyclic aromatic hydrocarbon derivatives such as anthracene, naphthalene, pyrene, rubrene and perylene, which are capable of carrying out hole transportation, light emission and/or electron transportation in an organic light emitting device.SOLUTION: An organic light emitting device comprises a first electrode, one or more organic layers and a second electrode, laminated successively, and at least one layer of the organic layers has a polycyclic aromatic hydrocarbon as a core and comprises at least one of derivatives in which a substituted or unsubstituted 2-30C cycloalkane, or a substituted or unsubstituted 5-50C polycycloalkane is directly combined with the core or with a substituent of the core by condensation. In addition, a new organic compound usable in the organic light emitting device is disclosed.

PROBLEM TO BE SOLVED: To provide a fullerene derivative allowing an organic photoelectric conversion element having a sufficiently high open-end voltage to be fabricated. SOLUTION: This fullerene derivative has both a structure represented by formula (1) and one or more structures selected from the group comprising structures represented by formula (2-1) and structures represented by formula (2-2). In formula (1), the ring A is a fullerene skeleton ≥60C; the ring B is a 3-6C carbocycle or a 3-6C heterocycle; R is a monovalent organic group; k is an integer of 1 to 8; and when multiple R's are present, the R's may be the same or different from one another.

PROBLEM TO BE SOLVED: To provide a substance for the preparation of a medicament of non-insulin dependent diabetes mellitus, hypertension and/or metabolic syndrome.SOLUTION: The substance includes the chemical structures of bicyclo[3.2.1]octane or the chemical structures of kaurene for the use in a dietary supplementation or as a constituent in a medicament for the treatment of non-insulin dependent diabetes mellitus, hypertension and/or the metabolic syndrome. The unique chemical structures of bicyclo[3.2.1]octane alone or in a kaurene structure provides the substances, such as e.g. steviol, isosteviol and stevioside with the capability of enhancing or potentiating the secretion of insulin in a plasma glucose dependent manner.
