We developed a compact measurement system for surface plasmon fluorescence spectroscopy (SPFS) and a sensor surface for the detection of 2,4,6-trinitrotoluene (TNT). We employed a laser diode as a light source in the optical system for exciting fluorescence. Then, a fan-shaped beam was irradiated from the laser diode to a Au thin film using a beam expander. Fluorescence emission was captured using...
Chlorophyll derivatives that possessed a phenylsulfanyl group at the C3 1 - or C3 2 -position were synthesized and their optical properties were investigated. Methyl 3 1 -phenylsulfanyl-mesopyropheophorbide-a was prepared by substitutions of the corresponding C3 1 -hydroxy-chlorin, methyl bacteriopheophorbide-d, with thiophenol in the presence of zinc iodide or of the...
