Paragraph 0026-0074, (2021/07/10)
The invention provides a spirofluorene organic laser material based on trifluoromethyl benzene functionalization. The material is characterized in that the compound takes two trifluoromethyl phenyl groups as end-capping groups and is bridged through n spirofluorene groups, and in the general formula I, R1 and R2 independently represent a straight chain, a ring-shaped chain, a branched alkyl chain and an alkoxy chain containing hydrogen or 1-12 carbon atoms, and n is 1, 2 or 3. By changing the spirofluorene groups in the middle and substituent groups on the spirofluorene groups, a molecular pi conjugated system, a topological structure, an electronic structure and solubility are regulated and controlled, and the photoelectric characteristics of the material are regulated. The structure is simple, the light and heat stability is good, the synthesis process is simple, the yield is very high, and industrialization is facilitated. The preparation of the organic microcrystal material does not need any surfactant, and the organic microcrystal material is regular in morphology and low in ASE threshold value, and can be applied to the organic electronic field of organic laser gain media and the like.

We have demonstrated B2pin2 as superior deoxidizing agent for the reductive deoxygenation of quinol derivatives under basic conditions. A wide range of highly functionalized phenols were obtained in good yields including a complex drug molecule, which revealed the high functional group tolerance of this protocol.
