在偶极（μ（g）=10.4 D）D-π-A mercury染料的噻吩供体（D）和噻唑受体（A）杂环上连接大体积取代基提供了固态下常见的反平行超分子二聚体基序的大于1 π的膨胀，使得能够在两个剩余π-面中的每一个上与两个其他相邻分子非常紧密的π-接触（3.36 π）。这种不寻常的填充基序导致空穴传输的三维渗透路径，并提供迁移率高达0.64 cm（2）V（-1）s（-1）的薄膜晶体管。
Attachment of bulky substituents at both thiophene donor (D) and thiazole acceptor (A) heterocycles of a dipolar (μ(g)=10.4 D) D-π-A merocyanine dye affords a more than 1 Å expansion of the common antiparallel supramolecular dimer motif in the solid state, enabling very close π-contacts (3.36 Å) to two other neighbor molecules on each of the two remaining π-faces. This unusual packing motif leads to three-dimensional percolation pathways for hole transport and affords thin-film transistors with mobility up to 0.64 cm(2) V(-1) s(-1).
