This work explores the layer-by-layer (LbL) fabrication of [Cu₂(bdc)₂(bpy)]_n thin films by using pyridine and acetic acid as capping agents onto mesoporous titania surface. While in the presence of acetic acid highly-ordered crystals with nanoplate morphology are formed, modulation with pyridine gives rise to formation of leaf-like crystals. In addition, processing sequence also matters when modulator is added. According to our results, modulators should be added to metal solution rather than linker/pillar during LbL assembly. These films were subsequently shown to generate photocurrent in a sandwich-type Grätzel solar cell device in response to simulated 1 sun illumination. The results also demonstrated that the device consisted of well-aligned nanoplates exhibits higher power conversion efficiency than the similar cell with disordered leaf-like crystals after iodine loading.

这项工作探索[Cu ₂（bdc）₂（bpy）] _n的逐层（LbL）制造通过使用吡啶和乙酸作为封端剂在中孔二氧化钛表面上形成薄膜。尽管在乙酸的存在下形成具有纳米板形态的高度有序的晶体，但是用吡啶进行调制会导致形成叶状晶体。另外，当添加调制器时，处理顺序也很重要。根据我们的结果，在LbL组装过程中，应将调节剂添加到金属溶液中，而不是连接剂/支柱。这些膜随后显示出在三明治型Grätzel太阳能电池装置中响应模拟的1个太阳光照而产生光电流。结果还证明，由排列良好的纳米板组成的装置与碘加载后具有无序叶状晶体的类似电池相比，具有更高的功率转换效率。
