Reduced graphene oxide (rGO) and its derivatives functionalized with 2-thiophene acetic acid (rGO-f-TAA) and grafted with poly (3-dodecylthiophene) (rGO-g-P3DDT) and poly (3-thiophene ethanol) (rGO-g-PTEt) were prepared to design the donor-acceptor supramolecular structures based on the regioregular poly (3-hexylthiophene) (P3HT). The P3HT nanofibers, which were pre-grown in a separate system and possessed the π-stacked P3HT backbones in the length of fibrils, were perpendicular to the rGO surface in the solution and, consequently, they inclined onto the substrate during solvent evaporation. Through this inclination, the orientation of P3HT chains changed from face-on to edge-on. In rGO-f-TAA systems, for either short (80 nm) or long (420 nm) P3HT nanofibers, the P3HT nanofibers were attached from their sides onto the rGO. The appearance of (020) and (002) spots in selected area electron diffraction (SAED) patterns proved a fixed edge-on orientation even after solvent evaporation. Functionalization of rGO surface with 2-thiophene acetic acid altered the tethering tendency of P3HT chains from the thiophenic rings to the hexyl side chains. Via grafting the rGO with P3DDT and PTEt, the tethered P3HT nanofibers were perpendicularly fixed onto its surface with a face-on orientation having (002) and (100) spots even after solvent evaporation, resulting in the conductivity range of 9.9–10.9 S/cm. The pre-developed large single crystals were also employed to construct the donor-acceptor supramolecules with edge-on oriented P3HTs. Further tethering of P3HT fibrils onto the rGO based micron sheets reflected a red-shifting and more intensified A_0–2, A_0–1, and A_0–0 peaks in the ultraviolet–visible spectra. A quenching in the photoluminescence spectra was observed in longer preparation time (18 h) based on the charge transferring from donor (P3HT) to acceptor (rGO derivatives).

还原的氧化石墨烯（rGO）及其衍生物用2-噻吩乙酸（rGO- f -TAA）功能化并接枝有聚（3-十二烷基噻吩）（rGO- g -P3DDT）和聚（3-噻吩乙醇）（rGO-制备了β-PTEt，以基于区域规则的聚（3-己基噻吩）（P3HT）设计供体-受体超分子结构。P3HT纳米纤维在一个单独的系统中预先生长，并在原纤维的长度上具有π堆积的P3HT主链，它们垂直于溶液中的rGO表面，因此，在溶剂蒸发过程中它们会倾斜到基底上。通过这种倾斜，P3HT链的方向从面朝边变为了边沿。在rGO- f-TAA系统，对于短（80 nm）或长（420 nm）P3HT纳米纤维，P3HT纳米纤维从侧面附着到rGO上。即使在溶剂蒸发后，在选定区域电子衍射（SAED）图案中出现的（020）和（002）点也被证明具有固定的边沿取向。用2-噻吩乙酸对rGO表面进行功能化改变了P3HT链的束缚趋势，从噻吩环到己基侧链。通过将rGO与P3DDT和PTEt接枝，即使在溶剂蒸发后，系留的P3HT纳米纤维也以面对面的方向垂直固定在其表面上，该表面具有（002）和（100）个斑点，从而电导率范围为9.9-10.9 S /厘米。预开发的大型单晶也被用于构建具有边缘定向P3HTs的供体-受体超分子。紫外可见光谱中的_0–2，A _0–1和A _0–0峰。基于电荷从供体（P3HT）转移至受体（rGO衍生物）的过程，在更长的制备时间（18 h）中观察到了光致发光光谱的猝灭。
