Langmuir-Blodgett films of 9-phenyl anthracene molecules incorporated into different matrices.
This communication reports the surface pressure (pi) versus area per molecule (A) isotherm characteristics of the mixed films of 9-phenyl anthracene (PA) in stearic acid (SA) and polymethyl methacrylate (PMMA) matrices, at the air-water interface. The mixed Langmuir films at the air-water interface have been observed to be easily transferred onto solid substrates to form uniform Langmuir-Blodge...
متن کاملRole of various LB parameters on the optical characteristics of mixed Langmuir–Blodgett films
This communication reports the spectroscopic characterizations of mixed Langmuir–Blodgett (LB) films of non-amphiphilic N,N-bis (2,5-di-tert-butylphenyl)3,4,9-perylenedicarboximide (DBPI) molecules, mixed with polymethyl methacrylate (PMMA) and stearic acid (SA). Jaggregates of DBPI molecules in the mixed LB films have been confirmed by UV–Vis absorption spectroscopic study. Formation of organi...
متن کاملRole 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...
متن کاملAgeing 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....
متن کاملOrientation and conformation of octadecyl rhodamine B in hybrid Langmuir–Blodgett monolayers containing clay minerals
To control the molecular organization of octadecyl rhodamine B (RhB18), hybrid Langmuir–Blodgett monolayers containing clay minerals were prepared. The orientation and conformation of the RhB18 molecule were analyzed by polarized attenuated total reflection Fourier transform infrared (ATR–FTIR) spectroscopy and fluorescence spectroscopy. Monomers and dimers of RhB18 were observed by UV-Vis abso...
