Description

TCI D4299 is trans,trans-1,4-Distyrylbenzene, a conjugated hydrocarbon built around a central benzene ring bearing two styryl groups at the para positions, both in the trans configuration. The compound serves as a non-heterocyclic building block and, at the same time, as a model oligomer for poly(phenylene vinylene), one of the important families of luminescent polymers in organic electronics. Because its structure is rigid, planar, and fully conjugated, laboratories widely use this material as a test substance for studying light absorption, luminescence, and charge transport behaviour.

The property that makes this compound a preferred choice is its continuous conjugation across three aromatic rings linked by trans vinylene bonds, which produces strong luminescence in the blue region together with emission quantum yields that are attractive for optoelectronic materials research. The well-defined trans,trans configuration ensures a flat and uniform molecular geometry, so spectroscopic measurement results can be compared between laboratories without interference from isomer mixtures. The planar framework also promotes ordered packing in the solid state, allowing researchers to study how aggregation affects both the colour and the intensity of emission. Beyond this, the vinylene double bonds provide reactive sites for further chemical elaboration.

In Indonesian laboratories, this material is typically handled in university and institutional research groups working on organic electronics, photophysics, and synthetic materials chemistry. It is generally used at small scale for preparing solutions for absorption and fluorescence measurements, for depositing thin films, and as a starting material in the synthesis of larger conjugated structures. Its role as a reference-grade model oligomer makes it well suited to teaching laboratories and to research programmes that need reproducible photophysical benchmarks.

Laboratory Applications

Absorption and fluorescence spectroscopy: the continuous conjugation across three aromatic rings gives strong, well-defined optical transitions, making this compound a dependable test substance for calibrating and validating spectroscopic measurements.
Photoluminescence studies in the blue region: strong blue emission and attractive emission quantum yields allow researchers to investigate emission mechanisms without requiring additional sensitisers or complex sample preparation.
Model oligomer studies for poly(phenylene vinylene): as a defined short-chain analogue of an important luminescent polymer family, it lets laboratories study polymer photophysics using a single, structurally unambiguous molecule.
Charge-transport and organic electronics research: the rigid, planar, fully conjugated framework supports investigations of charge transport behaviour relevant to luminescent polymer devices and organic semiconductor materials.
Aggregation and solid-state packing studies: the flat molecular skeleton encourages ordered packing in the solid state, enabling systematic study of how aggregation shifts emission colour and intensity.

Handling and Storage

Store the material in its tightly closed original container in a cool, dry, and well-ventilated place, protected from light, since conjugated compounds containing vinylene double bonds are best kept away from prolonged light exposure. Amber glass or the supplied container is suitable for storage, and the container should be reclosed promptly after each use to limit moisture uptake. Handle the solid in a fume hood or a well-ventilated area, avoid generating dust, and wear standard laboratory personal protective equipment including a lab coat, safety glasses, and chemical-resistant gloves. Consult the manufacturer's Safety Data Sheet before use and dispose of residues according to institutional chemical waste procedures.
