Fluorescein dimethacrylate

Fluorescein Dimethacrylate

Fluorescein dimethacrylate is a fluorescent, methacrylate-functional monomer designed for incorporation into polymer systems via free-radical polymerization. It combines the optical properties of fluorescein with reactive methacrylate groups, enabling the formation of photopolymerizable materials with intrinsic fluorescence.

This dual functionality allows fluorescein dimethacrylate to be covalently integrated into polymer networks, maintaining fluorescence within the material rather than relying on physical blending. It is commonly used in applications where visualization, tracking, or optical response is required within polymer matrices.

Functional Role

Fluorescein dimethacrylate functions as a fluorescent crosslinking monomer that integrates optical functionality directly into polymer networks. The methacrylate groups participate in polymerization, while the fluorescein moiety provides a stable fluorescent signal. This allows materials to be monitored, imaged, or tracked without relying on non-covalent dyes.

Why Use a Fluorescent Reactive Monomer?

Unlike physically blended fluorescent dyes, reactive monomers such as fluorescein dimethacrylate become part of the polymer structure. This reduces dye migration and improves signal stability, particularly in systems exposed to solvents, mechanical stress, or long-term use.

Handling & Storage

• Store in a cool, dry place in a tightly sealed container.
• Protect from light to preserve fluorescence properties.
• Handle using appropriate laboratory safety practices.
• Consult the SDS for detailed handling and safety information.

What is fluorescein dimethacrylate used for?

It is used to create fluorescent polymer materials for imaging, sensing, coatings, and photopolymer systems.

How is this different from fluorescein dye?

Unlike standard fluorescein dyes, this material contains methacrylate groups that allow it to be covalently incorporated into polymers.

Can this be used in photopolymerization?

Yes. The methacrylate groups are compatible with free-radical and UV-initiated polymerization systems.

Does the fluorescence remain after curing?

Yes. Because the molecule is incorporated into the polymer network, fluorescence is retained after polymerization.

What are the excitation and emission wavelengths?

Typical values are approximately 470 nm excitation and 511 nm emission.
