The invention provides a compound with a structure represented by a formula (I) and a preparation method and application thereof. The compound with the structure represented by the formula (I) is a dendritic bipolar main body material taking triazine as a central core, the structure is different from a D-pi-A type structure of a traditional dendritic bipolar main body; the central core triazine isused as an electron acceptor (A), peripheral branches are used as electron donors (D), and a D-A type dendritic bipolar main body formed by direct connection of the donors and the acceptors maintainsa high triplet state energy level (2.8-3.3 eV), so that the application of the bipolar main body to a blue light OLED device is facilitated; it is found through experiments that the maximum current efficiency of a blue phosphorus photoluminescence device prepared with the compound as a main body material can reach 46.7 cd/A, the maximum power efficiency can reach 50.11 m/W, the maximum brightnesscan reach 32000 cd/m, and the turn-on voltage is 2.4 V.

The synthesis of chiral, nonracemic butadienylcarbinols by employing intermediate (trimethylsilyl)methylallenic alcohols is described. Allenic alcohols are obtained by treatment of aldehydes with (4-bromobut-2-ynyl) trimethylsilane in the presence of a ca
