General description
α,α-Dibromotoluene undergoes polymerization with excess Mg to give poly(phenylmethylene)s. It reacts with NaSO2Me at 110°C to yield a mixture of the monosulfone and α,α-disulfone. It undergoes copolycondensation with α,α′-dibromo-p-xylylene in the presence of excess Mg via nucleophilic substitution of in situ generated Grignard reagents.

Common bacterial pathogens have become resistant to traditional antibiotics, representing an indispensable public health crisis. Photodynamic therapy (PDT), especially when common visible light sources are used as photodynamic power, is a promising bactericidal method. Based on the special photodynamic properties
