Abstract: The present disclosure provides a composition containing an iridium complex represented by general formula (1) below and a halogen atom. The content of the halogen atom is less than 5 ppm. In general formula (1), R8 to R20 are each a hydrogen atom or a substituent. R14 is an electron-withdrawing substituent having a Hammett constant ?m of 0.3 or more, and R1 to R7 are each a hydrogen atom or a methyl group.

Abstract: An organic metal complex represented by formula (1) and having a ligand represented by formula (2). MLmL?nL?l??(1) In formula (1), M represents a transition metal, and Lm, L?n, and L?l represent ligands different from each other. In formula (2), R11 to R14 are each independently selected from the group consisting of a hydrogen atom and a substituent. X is selected from the group consisting of CRR?, SiRR?, S, SO, and SO2. Y1 to Y6 are each independently selected from the group consisting of a carbon atom and a nitrogen atom. When Y3 to Y6 are carbon atoms, each of the carbon atoms may be bound to a carbon atom adjacent to the carbon atom to form a ring structure.

Abstract: In a glass-ribbon conveyance assisting device which is applied to a glass-ribbon conveyance device configured to convey a glass ribbon on a plurality of rotating glass-conveyance rolls, the glass-ribbon conveyance assisting device includes a rotary drive section, a plurality of rolls configured to be rotated by the rotary drive section, an annular belt configured to rotate while running with flexion under a state where the rolls have been inserted into the belt, and a wheel configured to press the glass ribbon which is conveyed on the belt. The glass ribbon is conveyed on the belt by a drive of the belt under a state where width-directional both end portions of the glass ribbon are sandwiched between the belt and the wheel.
