摘要：

Organic phosphorescence materials demonstrate potential optoelectronic applications due to their remarkably ultralong organic phosphorescence(UOP) lifetime and abundant optical characteristics prior to the fluorescence materials.For a better insight into the intrinsic relationship among regioisomeric molecules,crystalline interactions,and phosphorescence properties,three crystalline dicarbazol-9-yl pyrazine-based regioisomers with para-,meta-and ortho-convergent substitutions(p-DCzP,m-DCzP,and o-DCzP) were designed and presented gradually increased UOP lifetimes prolonging from 63.14,127.93 to350.46 ms,respectively,due to the regioisomerism effect(RIE) which would be an effective strategy for better understanding of structure-property of UOP materials.
