Abstract: Organo-metallic complexes for opto-electronic and sensory devices and their use in such devices are provided. The organo-metallic complex (triplet emitter) consists of a metal center and chelate ligands. At least one of chelate ligands comprises an aromatic or fused aromatic ring(s). Each ligand is covalently substituted with at least one, preferably two charge transport groups (ctg). The metal center can be coordinated by a spectator ligand. Presence of two ctgs at each ligand is advantageous for applications in organic light emitting diodes (OLEDs). Charge transport units facilitate hole and/or electron transport to the molecular center and allow for efficient exciton formation directly on the complex. Presence of ctgs on each ligand provides a good shielding with respect to interactions with the environment. Emission quenching is strongly reduced and materials with high emission quantum yields are obtained.

Abstract: A toy doll is provided having a torso defined by a front surface and a back surface. The doll may additionally include legs extending from a lower portion of the torso, an image sensor located on the back surface of the torso, and an image display located on the front surface of the torso. The doll may additionally include a control panel integrated into the pelvic region of the torso, operatively interconnected with the image sensor and the image display, so that that the image sensor and the image display are controllable by using the control panel. The doll may further include fabric clothing covering the image display, permitting a user to create the appearance of personalized graphic clothing for the doll.

Abstract: A skill challenging puzzle game shaped like an space station comprises of three spherical members rotatably mounted on a circular disc-shaped main body. Each spherical member is rotatably mounted on a horizontal axis located at the periphery of the main body and consists of eight equal size sectors. The disc-shaped main body consists of an inverted upper saucer and a lower saucer mounted together and rotatable horizontally relative to each other about a central axis such that the upper portion of the spherical members may be scrambled from or matched with selected lower portion of the spherical members. The matched spherical members may be additionally rotatable relative to their horizontal axes to obtain various challenging combinations of colours or patterns provided on the spherical members.
