1. An aminated and/or sulfonated and/or otherwise substituted low molecular weight aromatic compound corresponding in structure to Formula (1)-(3):

OG Complex Work Unit Chemistry
wherein each R1-R4 in Formula (1), each of R1-R6 in Formula (2) and each of R1-R8 in Formula (3)
is independently selected from hydrogen; hydroxy; carboxy; linear or branched, optionally substituted, C1-6 alkyl, optionally comprising at least one heteroatom selected from N, O and S; linear or branched, optionally substituted, C1-6 alkenyl; linear or branched, optionally substituted, C1-6 alcohol; linear or branched, optionally substituted, C1-6 aminoalkyl; linear or branched, optionally substituted, C1-6 carboxyalkyl; linear or branched, optionally substituted, C1-6 alkoxy; linear or branched, optionally substituted, C1-6 aldehyde; carboxylic acids; ester; halogen; optionally substituted amine; amino; amide; nitro; oxo; carbonyl; phosphoryl; phosphonyl; cyanided and sulfonyl (—SO3H), and/or
wherein any two of adjacent substituents R1 and R2 and/or R3 and R4 of Formula (1) or any two of adjacent substituents of R1 and R2 and/or R3 to R6 of formula (2) or any two of adjacent substituents of R1-R4 and/or R5-R8 of formula (3) form at least one optionally substituted cyclic ring system,
provided that at least one of R1-R4 in Formula (1), at least one of R1-R6 in Formula (2) and/or at least one of R1-R8 in Formula (3) is selected from optionally substituted amine.
