An organic luminescent material includes a host luminescent material and a guest luminescent material. The host luminescent material includes a compound represented by formula (1), where n is 0&#x2dc;8; Rand Rrespectively represent H, CF, CN, CHor CH; Ris CHor one of substituents shown as follows: 

Organic luminescent material and organic electroluminescent apparatus

This invention relates to tetraphenylmethane-based oxadiazole molecules that act as electron transporting materials to be used in electroluminescent devices. The oxadiazole compounds are of the following formula. Each variable is defined in the specification. 

Oxadiazole tetramers

This invention relates to a method of preparing a compound of formula (I):The method includes reacting one or more compounds of formula (II):in the presence of a base and a halogenating agent. In formulas (I) and (II) above, each A, independently, is aryl or heteroaryl; each n, independently, is 0&#x2013;3; and each R, independently, is C&#x2013;Calkyl, C&#x2013;Ccycloalkyl, C&#x2013;Cheterocycloalkyl, aryl, heteroaryl, halo, cyano, nitro, OR, NRR, SiRRR, COOR, OC(O)R, C(O)NRR, N(R)&#x2014;C(O)R, or SOR; wherein each of R, R, and R, independently, is H, C&#x2013;Calkyl, C&#x2013;Ccycloalkyl, C&#x2013;Cheterocycloalkyl, aryl, or heteroaryl; thereby producing the compound of formula (I) in a one-pot reaction. This invention also relates to the compounds prepared by the method described above.

Tetraazaporphyrin compounds

This invention features a compound having the formula:X is O or NR; and each of Y and Z, independently, isin which each of R, R, R, and R, independently, is alkyl, cyclyl, heterocyclyl, aralkyl, aryl, or heteroaryl; Aris aralkyl, aryl, or heteroaryl; and Aris cyclyl, heterocyclyl, aralkyl, aryl, or heteroaryl; or Arand Artaken together is heterocyclyl, aralkyl, or heteroaryl. This compound can be used as a red light emitting material in an electro-luminescence device.
