Monolayer Studies Of Novel Synthetic Compounds And Biological Systems , Jingyuan Wang

Retrospective Theses and Dissertations

A general review on preparation and methods of characterization of monolayers was given in Chapter 1. Different projects were undertaken in the research of this dissertation. Neutron and X-ray reflection studies of fullerene C[subscript]60 and its derivative monolayers were performed in Chapter 1. Neutron and X-ray reflection measurements and surface pressure isotherms of spread films of C[subscript]60-dodecylamine adduct C[subscript]60-(NH[subscript]2(CH[subscript]2)[subscript]11CH[subscript]3][subscript]x and C[subscript]60-propylamine adduct C[subscript]60-(NH[subscript]2C[subscript]3H[subscript]7][subscript]x indicate that these C[subscript]60 ...

Photophysics Of A Novel Optical Probe-7-Azatryptophan And Its Application In The Study Of Protein-Protein Interactions , Yu Chen

Retrospective Theses and Dissertations

Time-resolved and steady-state fluorescence study of the biological optical probe, 7-azatryptophan, its chromophoric moiety 7-azaindole are performed in order to explain the observation that the fluorescence spectrum of 7-azaindole (7-azatryptophan) apparently consists of one band in water ([lambda][subscript]sp\max em = 386nm) whereas in alcohols the spectrum is bimodal (eg. for methanol, [lambda][subscript]sp\max em = 374, 505nm). Careful measurements of the fluorescence decay as a function of emission wavelength indicate a small amplitude of an ~70 ps decaying component at the bluer wavelength and a rising component of the same duration at the redder wavelengths. The small ...
