Coating defects often arise during application in the flash stage, which constitutes the ∼10 min interval immediately following film application when the solvent evaporates. Understanding the transient rheology and kinematics of a coating system is

The spectroscopic properties and photochemical behavior of methyl phenanthrene-9-carboxylate and of a primary, secondary, and tertiary phenanthrene-9-carboxamides have been investigated in the absence and presence of strong Lewis acids. The ground-st

The fluorescence self-quenching and photodimerization of three phenanthrene derivatives have been investigated. Methyl phenanthrene-9-carboxylate undergoes self-quenching with a rate constant of 1.2×10 9 M -1 s -1 in dichloromethane to form a weakly
