[Problem] to selectively position the two hydroxyl groups are introduced to clean the sensor 4 [g, p] dibenzo, isomeric products is extremely small, can be made selectively and easily manufacture, and dibenz [g, p] new clean derivative manufactured by the manufacturing method of a sensor. (1) Dibenzo [g, p] [solution] clean sensor brominated, step 4 synthesis of bromide, bromine atoms (2) bromide 4 silylated, silylation process for synthesizing, and, (3) silylation of hydroxy-silyl group by oxidation reaction, synthesis of 2, 7, 10, 15 having a hydroxyl group at step dibenzo [g, p] [g, p] decen tetra- hydroxy dibenzo clean cleaning method for the production of derivatives of the sensor. Also, an oxygen functional group bonded to the dimerization of the fluorenone, 3, 6, 11, 14 and a hydroxyl derivative of [g, p] method for producing clean tetra- hydroxy dibenzo new sensor.

Regioselective direct tetra-bromination of dibenzo[g,p]chrysene (DBC) is described, involving the synthesis of multi-hydroxyl DBC derivatives. Addition of 16 equiv Br2 to a suspension of DBC in CH2Cl2 enables to singly construct a 2,7,10,15-tetrabromo-DBC. A lithium-bromine exchange event leads the corresponding silyl molecule, and the following oxidation formed a tetra-hydroxyl derivative. Its isomeric tetra-hydroxyl DBC as well as more congested octa-hydroxyl DBC were also singly constructed. These straightforward and simple synthetic routes would provide a general entry for new DBC materials.
