Photoluminescent supramolecular systems such as hydrogels and metal‐organic frameworks (MOFs) can be useful for applications in many areas. In aqueous media, lanthanides exhibit luminescence by sensitization through covalently linked chromophores (antenna effect), making them valuable for sensing and imaging applications. Fluorescent sensing by sensitized lanthanide emission in gels and MOFs provides a simple and rapid detection of analytes with high sensitivity and selectivity. This review presents the gradual evolution and the intriguing conceptualization of sensitized luminescence of lanthanides spanning the sensing of biomolecules, drugs, small organic molecules and enzymes employing hydrogels or MOFs as the sensing platform.

“…Metal–organic frameworks (MOFs) possess properties of high degree flexibility, including adjustable electrical [ 35 ], optical [ 35 ], and mechanical properties [ 36 , 37 ]. It has attracted much attention in the fields of electronic devices [ 38 , 39 ], such as memristors, field-effect transistors, supercapacitors [ 40 ], and various sensor architectures [ 41 – 43 ]. In recent years, MOFs have been applied in PSCs due to the properties of regular micro-pore structures and low-temperature process [ 44 – 48 ].…”

A dopant-free hole transport layer with high mobility and a low-temperature process is desired for optoelectronic devices. Here, we study a metal–organic framework material with high hole mobility and strong hole extraction capability as an ideal hole transport layer for perovskite solar cells. By utilizing lifting-up method, the thickness controllable floating film of Ni3(2,3,6,7,10,11-hexaiminotriphenylene)2 at the gas–liquid interface is transferred onto ITO-coated glass substrate. The Ni3(2,3,6,7,10,11-hexaiminotriphenylene)2 film demonstrates high compactness and uniformity. The root-mean-square roughness of the film is 5.5 nm. The ultraviolet photoelectron spectroscopy and the steady-state photoluminescence spectra exhibit the Ni3(HITP)2 film can effectively transfer holes from perovskite film to anode. The perovskite solar cells based on Ni3(HITP)2 as a dopant-free hole transport layer achieve a champion power conversion efficiency of 10.3%. This work broadens the application of metal–organic frameworks in the field of perovskite solar cells. Graphical Abstract

“…Compared with developed technologies [1] to detect gas molecules such as metal-oxide semiconductor sensor [2][3][4][5], infrared sensor [6,7], photoionization detector [8], electrochemical gas sensor [9,10] and gas chromatograph [11], Raman scattering technology has greater potential and a unique advantage. On the one hand, Raman scattering spectrum shows fingerprint characteristics of gas molecules, which can provide unique identification to detect gas in theory [12,13].…”

In order to address problems of safety and identification in gas detection, an optical detection method based on surface enhanced Raman scattering (SERS) was studied to detect ethanol vapor. A SERS device of silver nanoparticles modified polyvinylpyrrolidone (PVP) was realized by freeze-drying method. This SERS device was placed in a micro transparent cavity in order to inject ethanol vapor of 4% and obtain Raman signals by confocal Raman spectrometer. We compared different types of SERS devices and found that the modification of polyvinylpyrrolidone improves adsorption of ethanol molecules on surfaces of silver nanoparticle, and finally we provide the mechanism by theory and experiment. Finite Difference Time Domain(FDTD) simulation shows that single layer close-packed Ag nanoparticles have strong local electric field in a wide spectral range. In this study, we provide a case for safety and fingerprint recognition of ethanol vapor at room temperature and atmospheric pressure.
