Organic blue fluorescent material and preparation method and application thereof

The invention relates to an organic blue fluorescent material and a preparation method and application thereof. The material adopts a delta bond as a bridge chain to connect two anthracene molecule luminescence units and regulate the conjugation state of organic molecules; meanwhile, a steric hindrance group is introduced onto the delta bond to inhibit a pi-pi accumulation effect among the organicmolecules, and correspondingly the organic blue fluorescent material is prepared and has high thermal stability and high luminous quantum efficiency. The specific preparation method and application mainly include the steps of adopting 9-benzanthracene-10 borate and 4,4'-dibromo diphenyl bis-substituted methane for conducting a Suzuki coupling reaction to prepare the organic blue fluorescent material. The material is adopted as a luminous layer and achieves a non-doped deep blue OLED device with high performance.

Methane-perylene diimide-based small molecule acceptors for high efficiency non-fullerene organic solar cells

We report perylene diimide (PDI) small molecules based on diphenylmethane, triphenylmethane, and tetraphenylmethane cores, named PM-PDI2, PM-PDI3 and PM-PDI4, respectively. The OSC performances of PM-PDI3 and PM-PDI4 are comparable. The PM-PDI3 based device with PDBT-T1 as the donor achieved a highest power conversion efficiency (PCE) of 7.58% along with a high open-circuit voltage (VOC) of 0.98 V, a short-circuit current density (JSC) of 11.02 mA cm-2 and a high fill factor (FF) of 69.9%, a 1.32 times boost in PCE with respect to the PM-PDI2 based control device (3.26%). The high photovoltaic performance of the PM-PDI3 based device can be attributed to its relatively high-lying LUMO level, complementary absorption spectra with the polymer donor material PDBT-T1, relatively favorable morphology and improved exciton dissociation and charge collection efficiency. A PCE of 7.58% is among the highest efficiency of phenyl-methane as core based non-fullerene organic solar cells. Overall, this work provides a new approach to enhance the performance of non-fullerene acceptors.
