摘要： An amidinium-functionalized compound, characterized in that the compound has a structure according to General Formula I or General Formula II
wherein
• R5 and R9 are any substituent different from hydrogen;
• R1 to R4 are independently selected from the group consisting of an alkyl group, an alkenyl group, an alkynyl group, an aralkyl group, an alkaryl group, an aryl group and a heteroaryl group, or any of R1 and R3, R1 and R4, R1 and R2, R3 and R4, R2 and R3, or R2 and R4 represent the necessary atoms to form a five- to eight- membered non-aromatic ring;
• R6 to R8 are independently selected from the group consisting of hydrogen, an alkyl group, an alkenyl group, an alkynyl group, an aralkyl group, an alkaryl group, an aryl or heteroaryl group, a halogen group, an ether group, a nitro group, an amine group, or any of R5 and R6, R6 and R7, R7 and R8, or R8 and R9 represent the necessary atoms to form a five-to eight-membered ring;
• X- is an anion;
and wherein
• at least one of R1 to R9 comprises a polymerizable group or comprises the necessary atoms to link the amidinium group to a polymer.
