The two polymorphs can be identified by their characteristic low-wavenumber Raman modes and distinctive photoluminescence spectra that reflect different intermolecular coupling (J- and H-aggregates). One polymorph corresponds to the common single-crystal structure of PDIF-CN2, while for the other ...
In this work, staggered top-gate n-type organic thin film transistors (OTFTs) with evaporated PDIF-CN2 semiconducting layers, spin-coated Cytop™ dielectric barriers and channel lengths ranging from 100 to 2 μm were fabricated on polyethylene-naphtalate (PEN) substrates. Hexamethyldisilazane (...
(PDIF-CN2) molecules, a recently-introduced and very promising n-type semiconductor, have been evaporated on glass and silicon dioxide substrates to test the biocompatibility of this compound and its capability to stay electrically-active even in liquid environments.ResultsWe found that PDIF-CN2 ...
Biocompatibility tests, based on in-vitro cell cultivation, remark the need to functionalize the PDIF-CN2 hydrophobic surface by extra-coating layers (i.e. poly-L-lysine) to favor the growth of confluent cellular populations.Conclusions: Our experimental data demonstrate that PDIF-CN2 compound is ...
