Urinary 1-hydroxypyrene (1-OHP), one of the metabolite of polycyclic aromatic hydrocarbons (PAHs), has been extensively applied as a biomarker of animals and human exposure to PAHs. Herein, we synthesized a novel conjugated polymer poly-8-methoxy-7-methyl-5-(10-anthracen-9-yl)quinolone (PMMAYQ) using Suzuki coupling reaction, and then fabricated a homogeneous PMMAYQ/grahene multilayer film via layer-by-layer self-assembly technique and applied for electrochem. sensing of 1-OHP. Under the optimal conditions, {PMMAYQ-Graphene}16 modified glass carbon electrode exhibited excellent response for detection of 1-OHP. A linear range from 0.5 to 120 nM was obtained with a low detection limit of 0.07 nM (S/N = 3) and a sensitivity of 0.5539μA/μM. The electrochem. sensor exhibited excellent stability, accepted repeatability, and good selectivity. The developed method was employed for determination of 1-OHP in human urine samples and recoveries in the range of 95.6%-107.1% were achieved. The experimental process involved the reaction of 9,10-Dibromoanthracene(cas: 523-27-3COA of Formula: C14H8Br2)
9,10-Dibromoanthracene(cas: 523-27-3) can be sublimated and oxidized to generate anthraquinone. Soluble in hot benzene and hot toluene, slightly soluble in alcohol, ether and cold benzene, insoluble in water.COA of Formula: C14H8Br2
