The real-time second harmonic generation was employed to investigate the [2+2] photodimerization of styrylquinoline (SQ) derivatives in Langmuir-Blodgett (LB) monolayers deposited from aqueous subphases with different acidity. It was discovered that the photodimerization rate constant significantly decreased upon the addition of acid. The additional atomic force microscopy measurements revealed that surface morphologies were correlated to the photodimerization kinetics. These experimental results provide direct evidence for the topo-chemical mechanisms of [2+2] photodimerization in LB films. The current study demonstrates that the intermolecular interactions and aggregation structures play important roles in the photochemical properties at surfaces.
