The MnPc/FGT system exhibits a robust exchange bias of 1000 Oe at 10 K, with a record-high exchange bias-to-coercivity ratio of 0.37, attributed to the antiferromagnetic nature of MnPc. Surprisingly, the diamagnetic ZnPc induces a finite exchange bias of 200 Oe, highlighting the contribution of the emerging spinterface effect. In contrast, the metal-free H₂Pc yields no exchange bias, underscoring the essential role of designed molecules for magnetic interaction.

However, the performance of such OFETs strongly depends on the structure and morphology (more specifically, molecular arrangement and wettability) of the active layer, especially near the active-layer/gate-dielectric interface, and thus, their improvement is of prime importance. Focusing on these aspects, a systematic investigation was carried out for low-thickness active layers of such a material by molecular engineering and dielectric surface energy (DSE) tuning. Although DSE modification creates a minor impact on the Volmer–Weber (V–W)-type growth mode of DNTT thin layers, it produces a subtle difference in the morphology of the islands, namely, more columnar (i.e., better out-of-plane crystalline coherency) islands on the lower DSE substrate. Additionally, a strong 3D herringbone packing of DNTT molecules and a weak dielectric interfacial interaction lead to a dewetted island-like structure, restricting in-plane connectivity and hole mobility within layers of low thickness. On the other hand, DSE modification (from high to low) leads to a transition in the growth mode (from V–W to nearly Stranski–Krastanov type), a major change (improvement) in the morphology (wettability) of molecular-engineered S-DNTT-C10 thin layers, and a 3-fold improvement in the hole mobility, which is the maximum observed mobility for this molecule in such a low-thickness regime. Essentially, cofacial packing of S-DNTT-C10 molecules and the relatively strong interfacial interaction lead to wetted and better π-overlapped 2D layers, which improve the hole mobility and demonstrate that a synergistic approach of molecular engineering and DSE tuning is essential to improve the performance of DNTT-based OFETs, especially in the low-thickness regime.</p>","PeriodicalId":3,"journal":{"name":"ACS Applied Electronic Materials","volume":"7 19","pages":"9167–9176"},"PeriodicalIF":4.7,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145277568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
