Abstract:
The present invention relates to a novel triscarbazole compound having substituent on N-phenyl, which can be represented by Formula (I). wherein R 1 is selected from the group consisting of hydrogen, halogen or alkyl or alkoxy group having 1 to 20 carbon atoms wherein at least one hydrogen atom is optionally replaced by halogen; R A , R B , R C , R D and R E are any of substituents other than hydrogen wherein at least two of R 1 and R A may further form a fused ring; and i, j, k, l and m are same or different at each occurrence and represent an integer from 0 to 4, with the proviso that when R 1 is hydrogen, i is not 0. By introduction of the substituent on N-phenyl, the device efficiency, stability and lifetime can be increased while maintaining the solubility. These compounds can be used in various organic devices such as organic light emitting diodes, photovoltaic cells or organic semiconductor devices.

Abstract:
The invention involves encapsulation of phosphorescent molecules in polymeric matrices to prevent phosphorescence quenching. Specifically, polymers containing a significant portion of halogens have been found to be good matrices for encapsulation of phosphorescent molecules to provide strong phosphorescence at ambient conditions. Those encapsulated phosphorescent molecules can find a wide variety of applications for detection of many species, including biological and chemical molecules as well as micro-organisms.
