HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

2,5-Di(thiophen-2-yl)thieno[3,2-b]thiophene is a planar, electron-rich fused heterocycle featuring extended π-conjugation across three thiophene units. This architecture enhances charge carrier mobility and facilitates solution-processable film formation. The molecule exhibits high thermal stability and robust performance in organic semiconductors, particularly in thin-film transistors and photovoltaic devices.

Application

2,5-Di(thiophen-2-yl)thieno[3,2-b]thiophene serves as a robust π-conjugated building block for organic semiconductors, enabling efficient charge transport in solution-processed devices. Its fused tricyclic structure exhibits high thermal stability, excellent planarity, and favorable film-forming properties. The molecule functions effectively in donor-acceptor copolymers and facilitates controlled molecular packing, making it valuable for organic field-effect transistors and photovoltaic applications.
