| 英文摘要 | porphyrin platinum (it) complexes with efficient red phosphorescent emission have attracted extensive interest due to their potential application in the organic light emitting diodes (oleds). however, the strong pi-pi intermolecular interactions derived from their rigid planar coordination geometry result in the occurrence of self-quenching and affect their performance. in this work, a series of porphyrin platinum(ii) complexes with different peripheral substituents (pttemp, pttbmp, ptompp and ptdmpp) were designed, synthesized and characterized, for the purpose of effectively restraining the intermolecular pi-pi interaction. single crystal x-ray structure analysis indicated that they had ideal square-planar geometry around pt atom, and bulky t-butyl substituent could inhibit effectively pi-pi interactions. the peripheral substituents hardly affected absorption and emission properties of the complexes, and the luminescent peaks at 646-656 nm were assigned to (lc)-l-3 phosphorescent emission. pttbmp showed the highest emission quantum yield (0. 58) and external quantum efficiency(eqe, 6. 3%) due to strong steric effect of t-butyl. the luminous efficiency of ptdmpp with three methoxyl substitutents was better than ptompp with two methoxyl, the corresponding emission quantum yield were 0. 36 and 0. 29, and were 2. 4% and 1. 7%, respectively. the results indicated that the encapsulating effect of the peripheral substituents could improve luminescent efficiency of porphyrin platinum(ii) complexes. |
