According to the present invention, a noncovalent bond-modified carbon structure has advantages of: enabling the control of properties by controlling intervals between carbon structures according to the size and structure of a compound represented by Chemical Formula 1, which is inserted and adsorbed between the carbon structures; and enabling uniform dispersion in a polymer matrix without a change in intrinsic properties. In addition, a carbon structure/polymer composite comprising the modified carbon structure and a polymer matrix is simply manufactured and readily layered due to excellent orientation when forming a cured coating film, and thus can be useful for manufacturing a steel sheet having remarkable heat radiation, surface polarity, electrical properties and the like.

Size-Driven Inversion of Selectivity in Esterification Reactions: Secondary Beat Primary Alcohols

alcohols carrying large aromatic side chains with anhydrides differing in size and electronic structure have been measured. While primary alcohols react faster than secondary ones in transformations with monosubstituted benzoic anhydridederivatives, relative reactivities are inverted in reactions with sterically biased 1-naphthyl anhydrides. Further analysis of reaction rates shows that increasing substrate
