The purpose of this work is to determine the effect of substituents in the benzene ring on the efficiency of the adsorption of aromatic compounds on activated carbons. The paper considers the isothermal adsorption of nine monoaromatic compounds of the phenolic and aniline series from an aqueous ...
We prepared four types of trifluoromethyl-substituted polystyrenes. By substituting hydrogens at the ortho or meta positions of the benzene ring of polystyrene, we demonstrated that poly(2-(trifluoromethyl)styrene), poly(3-(trifluoromethyl)styrene), and poly(3,5-bis(trifluoromethyl)styrene) had ...

Novel boron 2-(2鈥 -pyridyl)imidazole (BOPIM) complexes T1 , T2 and T3 with different substituents (including bromo, tert -butyl and methoxyl) on the benzene ring of BOPIM dyes have been designed and synthesized, and their optical properties in both solution and the solid state were ...
of the weak interaction between a phenyl group in a stationary liquid and a benzene molecule in a sample alters most greatly when, among various substituents examined (e.g., Me, Et, Cl, and OMe), a methyl group—a "simple" nonpolar group—is introduced into a benzene ring in the ...

2) Are any substituents on a benzene ring ever going to be +I (well at least out of the more common groups that all have N, O or a halogen which mean the substituent is more electornegative then C). Are alkyl groups +I? Yup, they are. They're right in the middle of the list...
The absorption maxima, the quantum yields of cyclization and cycloreversion, and the fluorescence quantum yields of the open-ring isomers increased whereas the emission peaks decreased evidently when the methoxy group was attached at any of the three positions on the terminal benzene ring. Compared ...
