Generally, polyimides with an aromatic ring, such as 6FDA-TeMPD, have a high refractive index because of their high polarizability [14].
Phenylalanine is catalytically deaminated to cinnamic acid and then cinnamic acid is converted to various polyphenols, which share a definitive structural component: a phenol or an aromatic ring with at least one hydroxyl group.
2a), there are four possible fracture points during oil shale pyrolysis: 1) C-C bond at position [gamma] in the carbon chain branched to the aromatic ring, 2) C-C bond at position [alpha] in the carbon chain branched to the pyrrole ring, 3) C-C bond at position [beta] near the carboxylic acid species, and 4) C-N bond in the pyrrolic ring.
Of many structural type organic compounds, aromatic ring systems remain stable up to the temperature of pyrolysis (700C) whereas, aliphatic compounds with C-H and C-C bonds break into free radical molecular fragments quite readily which are further subjected to recombination (Golomb et al.
