Description
Technical field
The invention belongs to the synthesis technical field of polycyclic aromatic hydrocarbon compounds, be specifically related to a kind of six vast position six benzos
(hexa-cata-hexabenzocoronene, c-HBC) compound and the synthetic method of derivative thereof.
Background technology
The aromatic core of c-HBC and derivative thereof is distortion, and the distortion carbon atom of its planar central carbon atom near-end is because of sky
Between crowded and deviate 20 ° of plane, structurally in concave-concave conformation, compound that can be special with some, such as C60,
Form the complementary complex compound of geometry.C-HBC also has the construction unit of linear acene (linearacenes) simultaneously, and
This linear acene is well-known electronic material.In addition, the disk-like structure of c-HBC makes it a kind of
Potential column liquid crystal core, has good electron-transporting and good luminescence generated by light effect, and scene effect is brilliant
Body pipe, organic semiconducting materials, photovoltaic cell and photodiode have potential extensive application.
The synthesis of c-HBC in nineteen sixty-five reported first of Clar seminar (Tetrahedron 1965,21,
467-470).They are first prepared for the framework as target molecule for a kind of tetraalkoxide compound, then by this compound with
Copper powder mixes, and reacts and i.e. can get c-HBC, obtain product through column chromatography for separation, yield only about 2% at 400 DEG C.
The c-HBC of report and the best acquisition methods of derivative thereof have two kinds at present, and one is Nuckolls seminar
Development with pentacene quinone as raw material, through double Barton-Kelloggolefination reaction, or with virtue boric acid
Carry out the Suzuki coupling reaction of quadruple, obtain c-HBC and symmetrical the spreading out of minute surface thereof by Sholl cyclization further
