Rajagopal SK, Philip AM, Nagarajan K, Hariharan M. Progressive acylation of pyrene engineers solid state packing and colour via C-HH-C, C-HO and p-p interactions. Chem Commun (Camb). 2014;.
Quantum theory of atoms-in-molecules and Hirshfeld surface analyses indicated an increase in the extent of (i) C-HH-C; (ii) C-HO, (iii) p-p interactions and a decrease in the extent of (i) s-p interaction, (ii) an interplanar angle between the vicinal pyrene units in a series of acetylpyrene derivatives offering blue-green-orange emissive crystals.
