Formation of Metal-free J-aggregates in Merocyanine/Spiropyran Mixed Langmuir-Blodgett Film

Ageing effect of mixed Langmuir-Blodgett film of 9-Phenyl Anthracene in PMMA and SA matrices

This paper reports the time dependent changes of molecular arrangement in the mixed LB films of nonamphiphilic 9-phenyl anthracene (PA) in stearic acid (SA) and polymethyl methacrylate (PMMA) in the light of absorption and fluorescence spectroscopic study. Molecular movements have been observed in the recently lifted LB films and about 200 hours is required to get the films in stable condition....

Role of microenvironment in the mixed Langmuir-Blodgett films.

This paper reports the pi-A isotherms and spectroscopic characteristics of mixed Langmuir and Langmuir-Blodgett (LB) films of nonamphiphilic carbazole (CA) molecules mixed with polymethyl methacrylate (PMMA) and stearic acid (SA). pi-A isotherm studies of mixed monolayer as well as the remarkable change in collapse pressure of the mixed monolayer isotherms definitely show that CA is incorporate...

Langmuir-Blodgett nanorod assembly.

Techniques for directing the assembly of metal or semiconductor quantum dots into novel superstructures have been extensively pursued over the past decades.1-3 Recent interest has been drawn toward 1-dimensional nanoscale building blocks such as nanotubes, nanowires, and nanorods.4-14 If these one-dimensional nanoscale building blocks can be ordered and rationally assembled into appropriate 2-d...

Ferroelectric nanomesa formation from polymer Langmuir-Blodgett films

Organization of spin- and redox-labile metal centers into Langmuir and Langmuir-Blodgett films.

New sal₂(trien) ligands that contain alkoxy substituents of various length in meta position of the phenolate entities were coordinated to electronically and magnetically active iron(III) and cobalt(III) centers. The electrochemical and spectroscopic properties of these amphiphilic complexes are virtually unaffected upon alteration of the alkoxy substituents, thus providing a system in which the...
