PLA) materials have been utilized as biological oxygen sensors. Dyes with red-shifted
absorption and emission are important for multiplexing and in vivo imaging, thus hydroxyl-
functionalized dinaphthoylmethane initiators and dye-PLA conjugates BF2dnm (X) PLA (X=
H, Br, I) with extended conjugation were synthesized. The luminescent materials show red-
shifted absorbance (∼ 435 nm) and fluorescence tunability by molecular weight …
