Structural Investigation of Spiropyran Containing Langmuir-Blodgett Films using Scanning Probe Microscope Technique

Abstract
Scanning Maxwell stress Microscopy (SMM) which is a type of scanning probe microscopy designed to image microscopic electrical properties, have been applied to study the local surface potential distribution in photochromic spiropy ran dye Langmuir-Blodgett (LB) films. Using linear dependence between effective dipole moment and surface potential, structural change has been studied during photoisomerization.
