Green to Blue BODIPY Dyes for Fluorescent Applications in the Solution and the Solid State

Abstract

The present study demonstrates the physical properties of BODIPY dye with efficient absorption and fluorescence phenomena in the green region of wavelength between  (500-565) nm, the BODIPY dye adsorption over  the solid state on polydimethyl siloxane PDMS, was studied.  For this dye maximum absorption  was at 500 nm and a BODIPY dye signal in the polydimethyl siloxane compound PDMS indicates the presence of adsorbed dye in the higher concentration of BODIPY dye. The fluorescence of this dye in chloroform was measured, this  dye exhibited a maximum  fluorescence at  λ_em  at 512 nm at different concentrations. The maximum absorption of BODIPY dye with green BODIPY dye, was located at 517 nm, while the maximum absorption of 5,5-difluoro-1,3,7,9-tertamethyl-10-(3,4,5-tris(dodecyloxy)phenyl)-5H-4λ⁴,5λ⁴-dipyrrolo[1,2-c:2’,1’-f][1,3,2]diazaborinine eh236f1 compound was located at 511 nm.  On the other hand, the maximum absorption of BODIPY dye with blue BODIPY dye, was located at 517 nm.
