Self-assembled photo-responsive black phosphorus-azobenzene composite Langmuir films with chemical gas sensor and photoelectric conversion applications

Controllable-assembled functional monolayers by the Langmuir–Blodgett technique for optoelectronic applications

“…In photovoltaics, large-area, homogeneous and regular films are beneficial for building device systems for efficient light absorption and conversion, and the Langmuir technique can customize the optimal films. 205,206,216,217 As shown in Fig. 11F, Liu et al prepared ultrathin nickel-iron layered double hydroxide/dye LB semiconductor films on ITO substrates as photoanodes.…”

“…For example, Li et al modified the BPNS with polyethyleneimine (PEI) as a surface protective layer to enhance its stability. 217 They transferred multilayer BPNS-PEI/N-AZO LB composite films with modified BPNS combined with two azo-benzene containing compounds on ITO by the LB technique. Owing to the presence of j-type aggregates, the BPNS-PEI/N-AZO LB composite film electrodes exhibited excellent photoisomerization stability, sensitive acid–alkali gas responsiveness, and higher photoelectric conversion efficiency.…”

Enhanced thermal transportation across an electrostatic self-assembly of black phosphorene and boron nitride nanosheets in flexible composite films

“…21 The reported thermal conductivities of monolayer BP along the zigzag crystallographic direction, armchair direction, and through-plane are about 101, 36, and 5.5 W m −1 K −1 , respectively, as assessed by the time-resolved magneto-optical Kerr effect. 22 At present, BP is mainly used in photoelectric functional devices, 23,24 photosensitive thin films, 25 and other research fields, while research on BP-containing fillers as thermal management materials has rarely been conducted. Therefore, it is interesting and meaningful to investigate the potential of BP as a filler to enhance the thermal transport performance of thermal management materials.…”
