Abstract: A compound having a structure of the formula Ir(LA)(LB), in which LA is a bidentate, tridentate, tetradentate, pentadentate, or hexadentate ligand and LB is a monodentate, bidentate, tridentate, or tetradentate ligand, or not present, and where the total denticity of LA plus LB is 6, and LA includes at least one structure of Formula I: is disclosed as a useful phosphorescent emitter compound.

Abstract: A modular board game apparatus has a segmental playing surface comprising pairs of segments which are variously configured to provides a surface whose shape and playing area may be changed according to the requirements of a particular game. The segments facilitate versions of games normally only played between two players (such as chess and draughts) to be played by two, three or four people (Configurations II, III and IV). The board shapes described are each proportional in area to the number of players, are symmetrical, and may be variously patterned (6,7). A preferred embodiment comprising eight quadrilateral segments (3) that may be arranged in differing orientations, assembled and secured about a central point by means of a restraining ring (2) is illustrated. Segment sets comprising variously shaped segments of differing thickness can be assembled to simulate undulating terrain.
