Active interface architectures, exhibiting structural sensitivity to the
presence of chemical species or light, are of interest for sensor and functional
nanostructure applications. LCMRC researchers have demonstrated that it is
possible to use liquid crystals to read out the state of a photoactive monolayer
with great sensitivity to the incident wavelength. The wavelength dependent
photo-induced shape transition of interfacial molecules from linear (trans) to
bent (cis) produces distinct orientational changes in a contacting liquid
crystal layer that can in turn be read out optically. |
