二维聚合物纳米片最近获得了很多关注,特别是自上而下的纳米片,如石墨烯和金属硫属化物,源自体层母材料。虽然直接从分子组分制造的基于分子的自下而上的纳米片可以表现出比自上而下的纳米片更大的结构多样性,但迄今为止报道的自下而上的纳米片缺乏有用的功能。在这里,我们展示了自下而上的纳米片的设计和合成,其具有光活性的双(二吡啉合)锌(II)络合物基序。三元二吡咯配体和锌离子之间的液/液界面合成产生多层纳米片,而空气/液界面反应产生单层或少层纳米片,其中一侧的域尺寸>10 μm。双(二吡咯啉合)锌(II)金属络合物纳米片易于使用Langmuir-Schäfer工艺在各种基底上存款。沉积在透明SnO 2电极上的纳米片用作光电转换系统中的光阳极,因此是第一个光功能性自下而上纳米片。 从分子组分编织的功能性2D自下而上纳米片的创建仍然是一个巨大的挑战。在这里,一个自下而上的纳米片具有光功能的双(dipyrinato)锌(II)络合物基序的合成使用界面合成,使光电转换系统。
Two-dimensional polymeric nanosheets have recently gained much attention, particularly top-down nanosheets such as graphene and metal chalcogenides originating from bulk-layered mother materials. Although molecule-based bottom-up nanosheets manufactured directly from molecular components can exhibit greater structural diversity than top-down nanosheets, the bottom-up nanosheets reported thus far lack useful functionalities. Here we show the design and synthesis of a bottom-up nanosheet featuring a photoactive bis(dipyrrinato)zinc(II) complex motif. A liquid/liquid interfacial synthesis between a three-way dipyrrin ligand and zinc(II) ions results in a multi-layer nanosheet, whereas an air/liquid interfacial reaction produces a single-layer or few-layer nanosheet with domain sizes of >10 μm on one side. The bis(dipyrrinato)zinc(II) metal complex nanosheet is easy to deposit on various substrates using the Langmuir–Schäfer process. The nanosheet deposited on a transparent SnO2 electrode functions as a photoanode in a photoelectric conversion system, and is thus the first photofunctional bottom-up nanosheet. The creation of functional 2D bottom-up nanosheets woven from molecular components remains a large challenge. Here, a bottom-up nanosheet featuring a photofunctional bis(dipyrrinato)zinc(II) complex motif is synthesized using interfacial syntheses, enabling a photoelectric conversion system.
