Preparation method of 2-bromo-5-iodo-benzyl alcohol

The invention relates to the technical field of organic synthesis, and discloses a preparation method of 2-bromine-5-iodine-benzyl alcohol, which comprises the following steps: S1, o-benzylamine, a phase transfer catalyst, ammonium bicarbonate and an iodination reagent are subjected to iodination reaction to generate 2-methyl-4-iodoaniline; S2, the 2-methyl-4-iodoaniline is subjected to a diazotization reaction and a bromination reaction, and 2-bromine-4-iodobenzene is generated; S3, the 2-bromine-4-iodobenzene reacts with an initiator and N-bromosuccinimide, so as to generate 2-bromine-4-iodobromomethyl benzene; and S4, the 2-bromine-4-iodine bromomethyl benzene reacts with alkali, so as to generate the 2-bromine-5-iodine-benzyl alcohol. The preparation method disclosed by the invention is simple in process operation, few in three wastes and beneficial to industrial production; and no isomer is generated in the iodinated product, reduction of lithium aluminum hydride is not needed, and the problem of high operation risk caused by a large amount of hydrogen generated during reduction of lithium aluminum hydride can be effectively avoided.

Largely blue-shifted emission through minor structural modifications: Molecular design, synthesis, aggregation-induced emission and deep-blue OLED application

By simply introducing additional groups with different size and conjugation degree to the 2,2′-positions of BTPE, four BTPE derivatives are prepared which give blue or deep-blue EL emissions when used as emitters in non-doped OLEDs, as the result of the tuned dihedral angles of the biphenyl cores (up to ～89°), providing a new approach to design AIE luminogens with blue and deep-blue emissions.

Synthesis, mesomorphic behaviour and optical anisotropy of some novel materials for nematic mixtures of high birefringence

Structural moieties including core units (such as phenyl, naphthyl and thiophenyl), linking groups (such as ethynyl), terminal substituents (such as cyano, isothiocyanato and fluoro), and lateral fluoro substituents have been incorporated into novel mater
