The morphology manipulation of the active layers is important for improving the performance of organic photovoltaics(OPVs).The choice of processing solvent has great impact on the crystallization and phase separation during film formation,since solvent properties,including solvent effect on molecular crystallization,boiling point,and interaction parameters,can directly change the evolution pathways associated with thermodynamics and ***,revealing the underlying solvent-regulated morphology mechanism is potential to provide guiding strategies for device *** this study,chloroform,chlorobenzene,and toluene are used to process PM6:Y6 blends by slot-die printing to fabricate OPV *** chloroform printed film forms a fibrillar network morphology with enhanced crystallization,facilitating exciton dissociation,charge transport and extraction,resulting in an optimal power conversion efficiency of 16.22%.However,the addition of the additive chloronaphthalene in chloroform solution leads to over-crystallization of Y6,and thus,increasing domain size that exceeds the exciton diffusion length,resulting in lower device *** addition,both the chlorobenzene and toluene suppress the crystallization of Y6,which drastically decreased short-circuit current and fill *** results demonstrate the important role of processing solvent in dictating film morphology,which critically connects with the resultant printed OPV performance.

功能薄膜在光电器件、燃料电池、储能电池、气体分离、微电子及生物医学等领域表现出极大的应用潜力,成为学术界和工业界的研究重点.理解薄膜内部形貌形成机理,调控结晶行为和相分离结构,是提高薄膜器件性能的重要途径.散射技术,包括同步辐射X射线广角/小角散射(GIWAXS/GISAXS)、小角中子散射(SANS)、共振软X射线散射(RSoXS),作为表征薄膜内部微纳结构的有效手段,不仅可以研究薄膜材料的结晶行为,包括结晶强度、分子堆积方式和取向性质,还可以研究薄膜内的相分离行为和界面取向与粗糙度等结构细节.同时,原位散射技术可以实时检测薄膜形貌的形成过程,对理解非平衡态形貌形成机制具有重要意义.本文不仅总结了GIWAXS、GISAXS、SANS、RSoXS和原位散射技术的基本工作原理,还通过经典案例详尽地介绍了各形貌表征技术的功能和数据解析过程,为科研工作者快速选择合适的形貌表征技术提供指导作用.

In this study, a targeting micellar drug delivery system was developed for intravesical instilled chemotherapy of bladder cancer. The amphiphilic diblock copolymer poly（？-caprolactone）-block-poly（ethylene glycol）（PCL-b-PEO） with functional amino group（NH2） at the end of PEO block was synthesized. Then the copolymer was conjugated with folic acid（FA） and fluorescein isothiocyannate（FITC） via the PEO-NH2 terminus, and then assembled into micelles with the target moiety and fluorescence labeling. In addition, drug loaded micelles were also fabricated with anticancer drug doxorubicin（DOX） encapsulated in the hydrophobic core. The micelles were characterized in terms of size, drug loaded efficiency and critical micellization concentration（CMC） by means of DLS, UV and fluorescence spectra. In vitro cellular uptake and cytotoxicity studies showed that FA modified PCL-b-PEO-FA micelles have a greater targeting efficiency to human bladder cancer cell（T-24 cell） compared to PCL-b-PEO-NH2 micelles due to the conjugation of FA on the surface, while no targeting effect to normal tissue originated human embryonic kidney 293（HEK-293） cells was observed, enabling the micelles a promising drug carrier for intravesical instilled chemotherapy of bladder cancer.
