TCI D4617 is 2,8-Dimethylanthra[2,3-b:6,7-b']dithiophene, an organic semiconductor compound built from an anthracene core fused with two thiophene rings and carrying two methyl groups at the 2 and 8 positions. The material belongs to the anthradithiophene (ADT) family, which is widely used as the active layer in organic field-effect transistors (OFETs). In materials research laboratories, this compound serves as a p-type charge-carrier material that is deposited as a thin film and then electrically characterized to understand the relationship between molecular structure, crystalline arrangement, and charge mobility in organic electronic devices.

The main characteristic that makes this material a preferred choice is its extended, rigid conjugated aromatic framework, which promotes ordered molecular arrangement and good intermolecular orbital overlap. The methyl groups at both ends of the molecule help direct crystal packing while also maintaining the stability of the compound against oxidation compared with unsubstituted acene derivatives. No less important, this product is purified by sublimation, a purification method commonly required for electronic materials because trace impurities can act as charge traps and degrade device performance.

In Indonesian laboratories, this compound is typically used by university and institutional research groups working on organic electronics and materials science. It is handled in small quantities within thin-film deposition and device fabrication workflows, then evaluated using electrical characterization to correlate film morphology with transistor behaviour. Because the material is supplied in sublimation-purified form, it is generally reserved for experiments where film quality and reproducible device results are the primary concern.

  • Organic field-effect transistor (OFET) fabrication: the anthradithiophene framework acts as the p-type active layer, allowing researchers to build and evaluate working thin-film transistor structures.
  • Charge mobility studies: the compound is deposited as a thin film and electrically characterized so that charge-carrier mobility can be measured and related to processing conditions.
  • Structure-property relationship research: the defined methyl substitution pattern at the 2 and 8 positions lets researchers examine how substituents influence molecular packing and device behaviour.
  • Thin-film crystallinity and morphology investigation: the rigid conjugated core encourages ordered molecular arrangement, making it a useful model system for studying film growth and crystalline order.
  • Organic semiconductor material screening: because the product is purified by sublimation, it is suited to comparative experiments where impurity-related charge trapping must be minimized.

Storage store according to the manufacturer's instructions stated on the product label and safety data sheet
  • Chemical name: 2,8-Dimethylanthra[2,3-b:6,7-b']dithiophene
  • Purification: purified by sublimation

Store the container tightly closed in a cool, dry, and well-ventilated place, away from light, heat, and sources of ignition, and follow any specific storage conditions stated by the manufacturer on the label and safety data sheet. Keep the material in its original supplier container, or in a clean, dry, tightly sealed glass or amber vial when subdividing, and protect it from moisture and air where possible to preserve film quality. Handle the powder inside a fume hood or well-ventilated area to avoid dust generation and inhalation, and use standard personal protective equipment including a laboratory coat, safety glasses, and chemical-resistant gloves. Weigh and transfer small quantities using clean spatulas and dedicated glassware to prevent cross-contamination, which is particularly important for electronic-grade materials. Label all secondary containers clearly, keep the safety data sheet accessible in the work area, and dispose of residues and contaminated consumables through the laboratory's chemical waste procedures.
