3-Hydroxypropyl-functionalized Selenium-Substituted Nile Blue (NBSe-OH) is a structurally defined functional small molecule. The principal structural feature is a seleno-Nile Blue scaffold bearing a 3-hydroxypropyl group. Selenium substitution provides an elemental-composition comparison within related chromophore systems, while the hydroxyl site enables attachment to carriers or polymers. Absorption, dispersion, and relevant reaction behavior can be compared under matched media and optical measurement conditions to guide attachment strategies. The dye scaffold shown carries a single positive charge. The listed molecular formula excludes any unspecified counterion.
Applications:
- Selenium-substituted photosensitive materials;
- Sulfur/selenium structural comparisons;
- Carrier–dye conjugation.
